Alpine Guava is a mostly sativa cultivar bred by Sin City Seeds, a respected Nevada-based breeding collective known for precision selections and fruit-forward profiles. The strain’s name telegraphs its dual identity: a bright tropical guava character layered over crisp alpine pine and cool-mint top notes. Across consumer reports, Alpine Guava is described as energetic yet composed, making it a daylight-leaning option for creative or outdoor activities. It is positioned in the modern sativa-dominant category, with growers and reviewers consistently placing its effects in the uplifted, clear-headed spectrum.
Sin City Seeds has cultivated a reputation for carefully vetted parents and multiple filial selections, and Alpine Guava fits that approach. While some boutique cultivars can swing wildly in expression, Alpine Guava tends to present a fairly consistent guava-citrus and pine aromatic profile across phenotypes. The breeder’s involvement also signals a high standard of vigor and resin production, which many growers prioritize when choosing sativa-leaning lines. The combination of sativa architecture and dense resin makes it notable for both flower and live extract formats.
In modern markets, consumers gravitate toward strains that balance flavor with functional energy, and Alpine Guava sits squarely in that niche. Its sativa heritage helps deliver a fast onset and a long, tapering arc that many describe as productive rather than racy. The cultivar’s fruit-pine complexity appeals to terpene enthusiasts who seek both tropical sweetness and coniferous sharpness. As a result, Alpine Guava often earns a place in rotation for daytime sessions where clarity and sensory brightness are prioritized.
History and Breeding Context
Sin City Seeds emerged in the early 2010s with a focus on resilient hybrids and terpene-driven selections, operating out of the Las Vegas area. The group’s catalog has historically leaned into robust parent lines, and their projects often emphasize flavor without compromising yield. Alpine Guava reflects this ethos by blending an exotic fruit profile with the structure and vigor needed for commercial-scale cultivation. This balance is notable because many sativa-dominant strains can be temperamental or slow to finish.
The exact release window for Alpine Guava has not been formally stamped in trade publications, but grower chatter and menu archives suggest a late-2010s to early-2020s emergence. That timing tracks with a broader industry shift toward tropical fruit aromatics, as consumers sought alternatives to the dessert cookie and fuel-dominant waves. In that period, breeders increasingly showcased ocimene, terpinolene, limonene, and pinene-rich expressions to differentiate from ubiquitous Kush and Cookies genetics. Alpine Guava fits neatly into that trend, offering a clean, outdoorsy twist on guava sweetness.
As a mostly sativa cultivar, Alpine Guava functions as a counterbalance to heavier evening strains that dominated shelves during the mid-2010s. Sin City Seeds’ reputation likely helped the cultivar gain early traction with quality-focused growers. Over successive runs, feedback coalesced around its consistent terpene delivery and manageable flowering time for a sativa-leaning plant. That reliability is a big reason Alpine Guava remains a consideration for small-batch craft growers and scaled producers alike.
Genetic Lineage and Naming
Sin City Seeds bred Alpine Guava, but the breeder has not publicly released a definitive parentage list in widely accessible sources. This is not unusual; proprietary genetics remain a competitive advantage, and many breeders keep exact pairings in-house. Based on the name and sensory output, Alpine Guava almost certainly incorporates a guava-forward parent alongside a resinous selection expressing conifer and mint. Those alpine notes typically suggest contributions from pinene- or terpinolene-rich lines.
The term Guava in cannabis lineage often refers to two distinct traditions in modern breeding. One line references a tropical fruit-forward profile anchored by ocimene and limonene, sometimes seen in Papaya- or Mango-associated families. Another line references Guava-specific phenotypes within dessert or Gelato-related families that happened to present guava-like esters. Alpine Guava’s bright, crisp finish leans more toward the terpene-driven tropical-meets-pine camp rather than a dense, creamy dessert lineage.
The Alpine part of the name matters because it cues a resin quality and aroma reminiscent of mountain conifers, menthol, and fresh-cut wood. In many cultivars, these impressions correlate with alpha-pinene, beta-pinene, terpinolene, and sometimes borneol or guaiol. Such terpenes often deliver a perceived alertness and airways openness, traits commonly associated with functional sativas. Pair that with guava esters and citrus peel tones, and you arrive at a strikingly layered bouquet.
Growers should note that Alpine Guava is not the same as Strawberry Guava or Guava Gelato, which are separate projects from other breeders. The shared guava descriptor refers to overlapping flavor space rather than identical genetic heritage. When procuring seeds or cuts, confirm that Alpine Guava is explicitly labeled from Sin City Seeds to avoid mix-ups. Consistency begins with verified genetics and clear provenance.
Appearance and Structure
Alpine Guava tends to express a sativa-dominant morphology with elongated, tapering colas and a high calyx-to-leaf ratio. Nodes typically space moderately, offering good airflow that helps mitigate botrytis risk in dense canopies. In ideal conditions, growers report a stretch of approximately 1.7 to 2.3 times the vegetative height in the first three weeks of flowering. This predictable stretch makes it amenable to topping and screen-of-green setups.
The coloration leans lime to forest green with intermittent lilac or plum hues if nights dip below 64 degrees Fahrenheit, especially late in bloom. Pistils shift from pale tangerine to a deeper copper as the plant ripens. Trichome coverage is dense and sticky, with bulbous gland heads that turn from clear to cloudy and then selectively amber. Under magnification, resin heads often appear medium to large, a positive sign for solventless extraction yields.
Bud density lands between classic sativa spears and modern hybrid firmness, yielding conical flowers that trim cleanly. Fans are medium-sized with narrow leaflets, and the plant accepts defoliation without significant stress if done judiciously. Visual bag appeal is strong, as the crystal sheen stands out against vibrant greens and the occasional anthocyanin wash. Once dried properly, cured buds showcase a sparkling frost and an inviting, tropical-forest nose.
Aroma and Bouquet
The nose opens with ripe guava nectar and zesty citrus peel, quickly followed by alpine pine and crushed herb. Many users note a cooling impression akin to spearmint, suggesting a minor mentholated terpene component sitting behind limonene and pinene. On the break, the bouquet adds sweet florals and a faint peppery snap that registers as caryophyllene. The overall effect is bright, clean, and mouth-watering.
When ground, Alpine Guava releases a stronger pine-resin current with hints of passionfruit and green mango. The guava facet reads closer to pink guava than white guava, leaning sweeter and more aromatic. A fresh-cut wood tone appears in the mid-layer, likely the combined signature of pinene, terpinolene, and humulene. The combination feels both tropical and high-elevation at once, living up to its name.
After storage in a properly cured jar, the headspace skews citrus-forward with crisp herbal lift. Terpene preservation is critical; total terpene content around 2 percent or higher tends to intensify the fruit core. With time, the pine element deepens while the guava retains its candied flair, creating an evolving aromatic arc. This persistence makes Alpine Guava especially appealing for vaporization, where nuanced layers are easier to perceive.
Flavor and Palate
On the inhale, Alpine Guava presents sweet guava, lime zest, and a snap of pine needle. The mouthfeel is silky with a light menthol coolness that cleans the palate. As the vapor or smoke expands, secondary notes of passionfruit, lemongrass, and white pepper emerge. The sweet-tart balance makes for an engaging first impression.
Exhale introduces more resinous conifer and a faint herbal bitterness akin to grapefruit pith. A peppery sparkle brightens the back end, pointing to beta-caryophyllene activity. Vaporization at 370 to 395 degrees Fahrenheit preserves the high notes of guava and citrus while muting harshness. Going hotter in combustion brings out wood and spice and reduces the fruit clarity.
Across sessions, the flavor remains surprisingly stable if the cure is maintained at 58 to 62 percent relative humidity. In blind flight tastings, tasters often identify Alpine Guava by its pink-guava-meets-pine signature within the first few pulls. The finish is clean, with minimal lingering acridness when grown and flushed correctly. Pairing with sparkling water or citrus-forward tea further accentuates the guava glaze.
Cannabinoid Profile and Potency
As a modern, mostly sativa cultivar, Alpine Guava typically falls into the mid-high potency bracket common to contemporary hybrids. Reported lab results in markets where it has appeared place THC in a broad range of 18 to 26 percent by dry weight, with top-shelf phenotypes occasionally exceeding 28 percent under optimized conditions. CBD is usually minimal, often below 0.5 percent, leaving THC to drive the bulk of psychoactivity. Total cannabinoids commonly land between 20 and 32 percent in well-grown samples.
Minor cannabinoids appear in trace to low-percentage levels that can still influence the overall effect. CBG is frequently detected in the 0.1 to 1.0 percent range, which some users perceive as contributing to a more rounded clarity. THCV occasionally pings at trace levels below 0.3 percent, though expression varies widely by phenotype and cultivation. These minor fractions, while small, may subtly shape onset and subjective alertness.
For inhalation, most users report an onset in 2 to 5 minutes, with peak intensity around 30 to 60 minutes and a total effect window of 2 to 3 hours. Vaporization often feels cleaner and brighter, while combustion can feel punchier up front. Dose response follows the expected curve: 1 to 2 small inhalations produce light elevation, while 3 to 6 inhalations form a solid, functional high for many. Higher doses can shift the profile from focused to heady and racy, particularly for those sensitive to stimulating terpenes.
Edible preparations using Alpine Guava extract will mirror the underlying THC-forward nature. Onset typically ranges from 30 to 90 minutes, peaking by 2 hours and lasting 4 to 8 hours depending on dose and metabolism. Because of the limited CBD, first-time users should start low and step up gradually. As always, individual biochemistry and tolerance play a major role in perceived potency.
Terpene Profile and Chemistry
Grower-reported certificates of analysis for Alpine Guava commonly place total terpene content between 1.8 and 3.2 percent by weight when cultivated under optimal conditions. The dominant cluster tends to include one of terpinolene or limonene as a lead note, supported by beta-caryophyllene, ocimene, and alpha-pinene. In aggregate, this mix explains the tropical fruit top end, peppery sparkle, and brisk conifer finish. Minor terpenes such as humulene, linalool, and borneol may appear in the 0.03 to 0.2 percent range.
A representative terpene breakdown might look like: limonene 0.4 to 0.8 percent, beta-caryophyllene 0.3 to 0.7 percent, ocimene 0.2 to 0.5 percent, alpha-pinene 0.15 to 0.4 percent, and terpinolene 0.1 to 0.4 percent. When terpinolene climbs above 0.3 percent, the nose shifts more toward pine-citrus and green apple skin. When limonene dominates, the guava and citrus pop, while pinene keeps the finish brisk. Such swings are common across phenotypes and harvest windows.
From a pharmacological standpoint, beta-caryophyllene is a selective CB2 receptor agonist that has been studied for anti-inflammatory signaling in preclinical models. Limonene has shown anxiolytic-like effects in animal work and is hypothesized to modulate mood via serotonergic and dopaminergic pathways. Alpha-pinene is associated with bronchodilation and potential alertness, and may partially counteract short-term memory impairment from THC in some users. These findings should be interpreted as potential contributions rather than guarantees in any single session.
For preservation, terpenes with high volatility are most vulnerable to heat and oxygen exposure. Storage in airtight, UV-blocked glass at 60 to 68 degrees Fahrenheit helps slow oxidation. Minimizing headspace and avoiding repeated warm-cool cycles can maintain terpene content over weeks and months. Proper curing and storage can preserve 70 percent or more of the initial terpene load compared to loosely stored flower over the same period.
Experiential Effects and Use Cases
Users commonly describe Alpine Guava as uplifting, clear, and gently euphoric, with a functional energy that supports daytime tasks. The first 15 minutes emphasize mood lift, sensory brightness, and a light bodily activation. Many report increased talkativeness and a slight amplification of auditory and visual detail. This front-loaded clarity is why it often serves as a pre-activity choice for walks, creative work, or socializing.
At moderate doses, the strain tends to maintain focus and reduce mental clutter without feeling sedative. The pine-citrus signature can read as cooling and refreshing, which some interpret subjectively as increased alertness. After the first hour, the arc gently tapers into calm productivity rather than couch-lock. This profile suits errands, studio sessions, or weekend excursions.
At higher doses, the stimulation can tip into racy territory for those prone to anxiety with sativa-dominant strains. Individuals sensitive to terpinolene or limonene-driven cultivars should start with smaller inhalations and pace their intake. Reported side effects include dry mouth in roughly half to two-thirds of users and dry eyes in roughly a quarter, consistent with THC-rich inhalation. A small percentage report transient nervousness that resolves as the peak passes.
For pairing, Alpine Guava aligns well with light outdoor activity, board sports, or trail time where crisp aromatics feel congruent with the environment. Musically, clean, detailed genres such as acoustic jazz or minimal electronic can complement the strain’s sense of clarity. Culinary pairings that emphasize citrus, herb, and mineral notes feel synergistic, such as ceviche or a grapefruit and fennel salad. These pairings amplify the guava-zest top end while keeping the palate refreshed.
Potential Medical Applications
While not a substitute for medical advice, Alpine Guava’s mostly sativa profile aligns with use cases that prioritize alertness and mood support. Anecdotally, some users reach for it during periods of low motivation or mild fatigue, noting an increase in perceived energy without heavy sedation. The THC-forward cannabinoid mix may provide short-term distraction from stress, and the citrus-pine terpene set aligns with uplifting sensory cues. Individuals with anxiety sensitivity should proceed carefully, as stimulation can be a double-edged sword.
From a mechanistic angle, beta-caryophyllene’s CB2 agonism is of interest in inflammation-related discomfort, as shown in preclinical studies. Limonene has been explored for potential mood-modulating properties, and alpha-pinene’s bronchodilatory effect could contribute to a feeling of easier breathing in non-asthmatic individuals. These findings are not direct clinical endorsements but illustrate plausible pathways for perceived benefits. In practice, effects vary widely by dose, tolerance, and personal neurochemistry.
For pain, high-THC flower has shown meaningful analgesic potential in observational studies, especially for neuropathic profiles. Alpine Guava’s minor CBG fraction may contribute a subtle smoothing effect reported by some users, though data remains preliminary. Those seeking evening analgesia might prefer a heavier chemotype, but Alpine Guava can function as a daytime option for some. Pairing with CBD can temper overstimulation and round the edge if needed.
Common adverse effects include dry mouth, transient lightheadedness in sensitive individuals, and occasional situational anxiety at higher doses. Hydration, moderate pacing, and avoiding caffeine stacking can help reduce jitteriness. As always, patients should consult a clinician familiar with cannabinoid therapy, particularly when combining with existing medications. Start low and titrate until an optimal balance of function and relief is found.
Comprehensive Cultivation Guide
Alpine Guava cultivates like a modern sativa-dominant hybrid with strong vigor and predictable stretch. Indoors, a vegetative period of 3 to 5 weeks is typical before flip, depending on plant count and training. Expect a flower time of roughly 63 to 70 days, with some phenotypes finishing closer to 56 or pushing to 77 depending on environment and desired ripeness. The first 21 days of bloom bring the most vertical growth, averaging a 1.7 to 2.3 times stretch.
Lighting targets fall in the 600 to 900 micromoles per square meter per second PPFD range in mid flower for non-CO2 rooms. With CO2 enrichment at 800 to 1200 ppm, Alpine Guava can comfortably utilize 900 to 1100 PPFD, provided temperatures are raised 2 to 4 degrees Fahrenheit to maintain appropriate VPD. Daily light integral indoors typically sits between 35 and 55 mol per square meter per day for best results. Keep photoperiod strictly at 12 hours dark to avoid reveg signals.
Temperature in veg should land around 75 to 82 degrees Fahrenheit with 60 to 70 percent relative humidity. In flower, aim for 72 to 80 degrees Fahrenheit with RH at 50 to 60 percent in early bloom and 42 to 50 percent late to reduce botrytis pressure. VPD targets of roughly 0.9 to 1.2 kPa in veg and 1.2 to 1.6 kPa in flower keep transpiration efficient. Stable overnight temperatures and gentle airflow mitigate foxtailing on high-intensity setups.
Nutrient demand is moderate to high, with a noticeable appetite for calcium and magnesium, especially under intense LED lighting. In hydro or coco, a pH of 5.8 to 6.2 works well, while in soil 6.3 to 6.8 helps maintain micronutrient availability. Target EC in late veg at 1.4 to 1.8 mS per centimeter, rising to 1.8 to 2.2 mS per centimeter in mid flower for heavy feeders. Always read the leaves; Alpine Guava typically signals nitrogen excess with dark, overly waxy fans and clawing.
Training is highly recommended to manage canopy height and light penetration. Topping once or twice in veg, followed by low-stress training, sets a broad, even frame. A single-layer screen of green at 6 to 10 inches above the canopy can add 10 to 20 percent yield by converting vertical growth into lateral bud sites. Strategic defoliation around day 21 and day 42 of flower improves airflow and directs energy to sites with strong light exposure.
In organic living soil, Alpine Guava performs admirably with a strong microbe and mycorrhizae program. Top-dressing with balanced amendments at the flip and again at week four, coupled with compost teas, sustains an even feed. In mineral regimes, ensure a balanced NPK with early flower phosphorus support and a potassium bump from weeks three through seven. Supplement silica at 50 to 100 ppm to strengthen stems and resist mechanical stress.
Watering cadence should favor thorough saturation to a modest runoff, followed by full dryback in soilless media. In soil, maintain consistent moisture without waterlogging; a 10 to 15 percent pot weight drop before rewatering is a pragmatic rule of thumb. Oscillating fans should produce gentle leaf flutter across the canopy, and clean intake filtration reduces pests. A preventative integrated pest management program including beneficial mites and periodic enzyme sprays minimizes outbreaks.
Outdoor and greenhouse grows benefit from Alpine Guava’s airflow-friendly structure. In warm, arid to semi-arid climates, expect harvest in early to mid-October at temperate latitudes, with yields ranging from 600 to 900 grams per plant when planted early and trained. In cooler, wetter climates, aggressive pruning and rain protection are wise, and earlier-flowering phenotypes are preferred. Mulching and drip irrigation stabilize root-zone conditions during heat spikes.
Under competent indoor conditions, yields of 450 to 650 grams per square meter are achievable with SCROG and dialed environment. Per-watt benchmarks of 0.9 to 1.5 grams per watt are realistic under modern high-efficiency LED fixtures. Solventless hash yields vary by phenotype, but the large, bulbous heads and greasy resin suggest favorable returns in the 3 to 5 percent frozen input range for live rosin. Always phenotype hunt if possible to capture resin-rich selections that maintain flavor post-press.
As harvest approaches, watch trichome development closely. Alpine Guava generally shines when pulled at mostly cloudy with 5 to 10 percent amber for a bright uplift, or 10 to 15 percent amber for a slightly deeper body component. Flushing practices vary by system; many mineral growers run 7 to 10 days of reduced EC or water-only finish. In organics, a steady, tapering feed and a well-timed finish avoid sharp nutrient swings.
Harvest, Drying, and Curing
Alpine Guava’s terpene profile rewards a slow, controlled dry. Aim for 60 degrees Fahrenheit and 58 to 62 percent relative humidity for 10 to 14 days, depending on bud size and density. Gentle air exchange prevents stale pockets without creating direct airflow on flowers. Stems should snap rather than bend when ready to trim.
For trimming, a light touch preserves trichomes along the calyx and sugar leaf edges. If the canopy was healthy and clean, a hybrid trim works well: remove fans before drying and refine the shape after. Keep trim for extraction; Alpine Guava’s resin character often translates well into hash or hydrocarbon extracts. Collect and store trim frozen if the end goal is fresh-frozen processing.
Curing should proceed in airtight, food-grade glass jars with minimal headspace. Burp daily for the first week, then every two to three days for weeks two and three, adjusting for humidity. Use dedicated two-way humidity control packs if ambient conditions swing; target a stable 58 to 62 percent RH inside the jar. Four to eight weeks of cure typically optimizes flavor, with peak guava-pine expression developing around week six.
For long-term storage, keep jars in the dark at 60 to 68 degrees Fahrenheit and avoid repeated thermal cycling. Water activity between 0.55 and 0.65 helps preserve terpenes and prevent microbial growth. Properly stored, Alpine Guava can maintain bright aromatics and potency for several months. Label jars with harvest date, phenotype, and cure start to track best windows for consumption.
Quality Assessment and Pairings
Quality Alpine Guava expresses a vivid, tropical-pine aroma upon opening, without musty or grassy undertones. Buds should be moderately firm with a sparkling trichome glaze, and pistils should present a warm tangerine to copper tone. Break apart a nug and look for a juicy guava pop alongside clean resin notes; a dull or hay-like smell suggests rushed dry or insufficient cure. Vapor and smoke should feel cool and fragrant rather than harsh.
In beverage pairings, sparkling mineral water with a twist of lime or yuzu emphasizes the zest and keeps the palate brisk. A lightly hopped pilsner or a dry cider can harmonize with the pine-fruit interplay without overwhelming it. Nonalcoholic pairings like lemongrass tea or cold-brewed green tea with citrus peel show excellent synergy. Citrus-forward mocktails with mint garnish also echo the alpine coolness.
Culinarily, lean toward bright acidity and herbs. Grilled shrimp with chimichurri, mango salsa with Tajin, or a simple avocado and grapefruit salad complement Alpine Guava’s spectrum. For dessert, a guava-passionfruit sorbet or citrus olive oil cake with rosemary underscores the fruit and the forest. Keep fats moderate to avoid muting high-toned aromatics.
Responsible Use and Safety Notes
Alpine Guava’s mostly sativa nature can be stimulating, which is enjoyable for many but challenging for some. New users should take one or two small inhalations and wait several minutes to gauge response before continuing. Avoid stacking with caffeine if you are sensitive to jitteriness, especially on an empty stomach. Hydrate to counteract common dry mouth and dry eyes.
Do not drive or operate machinery under the influence, and adhere to local laws and age restrictions. If combining with prescription medications, consult a healthcare professional familiar with cannabinoids. Store products in child-resistant containers away from heat and light. Start low, go slow, and prioritize comfort and context for a good experience.
