Strata and Zappa are two of the most deliberately provocative hop varieties in the American catalog, both known for producing the cannabis-adjacent aromatic note that the craft beer world calls “dank,” and both used by brewers who want their IPA to push into territory that conventional tropical-citrus hops don’t reach. I’ve dry hopped with both in West Coast IPAs specifically to explore the dank end of the American hop spectrum, and the comparison reveals two genuinely different interpretations of what cannabis-forward hop character means in beer.
Strata vs. Zappa: key specifications compared
Strata (formerly OS 502): Developed by Oregon State University, released commercially 2019 by Indie Hops. Alpha acids: 11–14%. Beta acids: 5.5–6.5%. Cohumulone: 28–32% (moderate). Total oil: 1.8–2.5 mL/100g. Primary components: myrcene (45–55%), farnesene (18–24%, notably high, contributes the herbal-cannabis note), linalool. Primary flavor/aroma: cannabis, passion fruit, red berries, citrus, subtle earthiness, Strata produces one of the most explicitly cannabis-adjacent aromatic profiles in American hops, balanced by genuine tropical fruit complexity (passion fruit, berry) that keeps the hop interesting beyond just the dank note. The farnesene content drives the cannabis character; the myrcene and linalool contribute the tropical fruit complexity alongside it. Strata is polarizing commercially, some craft brewers market its cannabis character explicitly as a selling point; others find it creates association problems with drinkers who are confused or put off by the reference. Zappa: Developed from a Nevada wild hop discovered in the Cascade Mountains, released by Hollingbery & Son Hop Ranch commercially in 2020. Named after Frank Zappa. Alpha acids: 8–11% (moderate). Beta acids: 4–5.5%. Cohumulone: 30–36% (moderate). Total oil: 1.5–2.2 mL/100g. Primary components: myrcene (55–65%, very high), farnesene (12–16%). Primary flavor/aroma: cannabis, tropical fruit, citrus, slight dank earthiness, Zappa produces cannabis-adjacent character from very high myrcene combined with farnesene, producing a more resinous-myrcene-driven dank note than Strata’s farnesene-led cannabis character. Zappa is more purely dank with less tropical fruit complexity than Strata; the fruit is present but more muted relative to the resinous-dank note.
Cannabis-forward hops in brewing: Strata vs. Zappa
Use Strata when: you want cannabis-adjacent character with genuine tropical fruit complexity alongside it, Strata doesn’t just produce “dank” but produces dank-with-passion-fruit-and-berry that is more nuanced and interesting as a complete hop profile. Strata works best at dry hop rates of 0.5–0.75 oz/gallon where both the cannabis note and the tropical fruit character are legible; at very high rates (1+ oz/gallon solo), the cannabis character can become overwhelming without sufficient malt body to anchor it. Strata pairs well with Mosaic (adds blueberry-tropical depth alongside Strata’s berry-cannabis), Citra (citrus brightness balances the earthy dank note), and Idaho 7 (the tea-pine character of Idaho 7 provides an earthy grounding for Strata’s fruit-cannabis). Best styles: West Coast IPA, West Coast-NEIPA hybrid, any IPA where dank complexity is a design goal. Use Zappa when: you want maximum resinous-myrcene dank without fruit complexity moderating the character, Zappa produces the most straightforwardly dank, resinous, cannabis-forward profile of any mainstream American hop. Its wild hop lineage contributes an untamed quality that cultivated varieties bred for balanced complexity lack. Best used at low to moderate dry hop rates (0.25–0.5 oz/gallon) as part of a blend where its dank character adds dimension to a more complex hop combination. As a solo dry hop variety, Zappa’s lack of fruit complexity means the beer reads as one-dimensionally dank. Pairs well with: El Dorado (stone fruit against dank), Centennial (classic West Coast citrus-resin framework), Simcoe (amplifies resinous depth with pine). Important note: Both Strata and Zappa’s cannabis-adjacent character is from terpene chemistry (farnesene and myrcene), not from cannabinoids, neither contains THC, CBD, or any psychoactive compounds. The aroma resemblance is purely chemical and aromatic.
Common Questions
Are cannabis-forward hops legal and appropriate to brew with?
Yes, hops are botanically related to cannabis (both are in the Cannabaceae family), which is why certain terpene profiles in hops produce aromas reminiscent of cannabis. The compounds responsible (myrcene, farnesene, and related terpenes) occur naturally in hops and are fully legal, regulated brewing ingredients with no psychoactive properties. There are no legal restrictions on brewing with Strata, Zappa, or any other “dank” hop variety anywhere that homebrewing is legal. The cannabis resemblance is purely aromatic, tasting a Strata-dry-hopped IPA will not produce any effect beyond what any other hoppy IPA produces. For competition brewing: the BJCP and most homebrew competition judges evaluate dank character as a legitimate hop aroma note in West Coast IPA and related styles. Excessive dank character in a style where it’s out of place (German Pilsner, for example) would be marked as a fault, just as excessive citrus would be. In appropriate styles (West Coast IPA, Double IPA), well-integrated dank character from Strata or Columbus is a positive attribute. For marketing and serving: some brewers avoid explicitly naming the cannabis reference on their labels or tap handles to avoid confusion or association concerns; others (especially in US states where cannabis is legal) lean into the reference as a marketing angle. As a homebrewer, you can call it whatever you want in your notes.
