Deo Farms RS Line at Vermont Dispensaries: RS11 and Zoap Explained

Two of the most sought-after premium strains on Vermont dispensary menus in 2025 and 2026 trace to the same Oakland, California breeding operation. RS11 (Rainbow Sherbert #11) and Zoap both come from Deo Farms' RS line — a breeding program built on Rainbow Sherbet, Deo's cross of their own Pink Guava strain with Sunset Sherbet. They share the same genetic foundation and occupy the same premium tier on Vermont menus. But they are not the same strain, and choosing the wrong one for your situation is a predictable mistake. This guide is for Vermont consumers who want to understand what they are buying, how to tell the two apart by smell, and where to find them.

TL;DR

• Deo Farms — Oakland, CA breeding operation (DEO = Deep East Oakland). Run by Rob. Developed the RS line from Pink Guava × Sunset Sherbet.
• RS11 — indica-leaning, tropical-fruit + gas aroma (guava, mango, diesel), Limonene / Caryophyllene terpene lead varies by batch. Leafly HighLight January 2025. Co-selected with Wizard Trees. Confirmed at Upstate Elevator Supply Co., Burlington (Living Soil 3.5g).
• Zoap — balanced hybrid, soapy-floral-citrus aroma, consistent Limonene dominant → Caryophyllene → Linalool profile. Afternoon to early-evening use. Confirmed at Theory Wellness, Brattleboro.
• Fastest smell test: tropical fruit + diesel = RS11. Citrus + soap/floral = Zoap.
• Vermont law: all dispensary cannabis is Vermont-grown, so any RS-line strain on a shelf comes from a licensed Vermont cultivator working with Deo Farms genetics.

Who is Deo Farms?

Deo Farms is a breeding operation based in Oakland, California. DEO stands for Deep East Oakland, the neighborhood where the program originated. The operation is run by a breeder known as Rob, who developed an internal genetics program focused on pheno-hunting from specific parent crosses rather than broad commercial seed production. The RS line — Rainbow Sherbert line — is the most widely recognized product of that program.

Deo Farms is not a household name in the same way that Seed Junky Genetics (Wedding Cake, Kush Mints) or Sherbinski (Sunset Sherbet, Gelato) are — they are a smaller, craft-tier operation whose genetics became widely circulated because the specific phenotypes they selected were genuinely exceptional. RS11's spread to dispensary shelves across many states — recognized when Leafly named it the HighLight Strain of January 2025 — is the result of licensed cultivators adopting RS-line genetics, not a marketing operation.

A key clarification: Deo Farms' "Rainbow Sherbert" (the RS line) is a proprietary internal creation, distinct from "Rainbow Sherbet" seeds sold commercially by other breeders, which are typically a Zkittlez × Sunset Sherbet cross. They share a name but are genetically unrelated beyond both involving Sunset Sherbet somewhere in their tree. If you see "Rainbow Sherbet" on a seed bank's website or an unverified cannabis aggregator, that is not what RS11 and Zoap use as their parent material.

The RS line: how the genetics work

The line starts with Rainbow Sherbet — Deo Farms' cross of their proprietary Pink Guava strain with Sunset Sherbet. From open pollinations of that cross, Deo grew out large seed populations and selected standout phenotypes, numbering them sequentially: RS#11, RS#21, RS#54, and others. The strain we call RS11 is phenotype #11. Zoap is RS21 — but it is not a first-round selection like RS11. Deo went a generation deeper: he selected a Rainbow Sherbet female (reported as #16), crossed it back to a hardy Rainbow Sherbet male, grew out roughly a hundred of those seeds, and phenotype #21 became Zoap. That makes Zoap a Rainbow-Sherbet-on-both-sides selection, while RS11 is a direct pheno pick from the original cross.

Pink Guava is a Deo Farms proprietary selection, bred from OZ Kush — itself a cross of Zkittlez (the "Z") and OG (the Eddy Lepp OG cut). That OG heritage is the source of the diesel-gas backbone that appears in RS11 even as the tropical-fruit-and-guava top note dominates. Pink Guava is not sold commercially; it is an internal Deo Farms breeding tool, and it supplies the fruit-and-gas half of Rainbow Sherbet.

Sunset Sherbet is a Sherbinski strain bred in the Bay Area from Thin Mint GSC × Pink Panties. It is the dessert-sweet half of Rainbow Sherbet, and therefore sits in the ancestry of every RS-line strain. This is why both RS11 and Zoap carry the dessert-heritage sweetness of the broader Sherbet family — which also gave rise to Gelato, Runtz, and dozens of other modern hybrids — while having a distinctly different character from those strains because of Deo's Pink Guava foundation and independent selection work.

The practical upshot: RS11 and Zoap are close relatives that share the same two grandparents (Pink Guava and Sunset Sherbet, through Rainbow Sherbet), but they were selected at different depths in the line and express very differently. Zoap's double dose of Rainbow Sherbet is part of why it reads as the cleaner, more citrus-floral of the two, while RS11's single-generation pick keeps more of Pink Guava's gassy weight.

RS11: the indica sibling

RS11 (Rainbow Sherbert #11) is the heavier of the two RS-line siblings. It was selected from the original RS program by Deo Farms and, independently, by Wizard Trees (a Los Angeles operation). Both teams evaluated the same 120-seed pack and converged on phenotype #11 as the standout — a dual-team convergence that functions as a credibility signal, since two independent evaluators finding the same pheno exceptional without coordinating is a meaningful filter.

The aroma profile leads with tropical fruit — guava, mango, apricot, citrus — over a gas-diesel backbone inherited from Pink Guava's OZ Kush side. Reviewers frequently describe it as Rainbow Sherbet ice cream combined with diesel: the sweet-tropical top note floats recognizably above the fuel. On the COA, the terpene lead genuinely contests between Limonene and Caryophyllene depending on the batch; Leafly's aggregate data shows them running close together, with Humulene often appearing as the third named terpene (Myrcene appears in some panels instead).

RS11 is classified as indica-leaning — retailers widely cite 70/30 indica-dominant, though Leafly classifies it simply as hybrid. The effects open euphorically (mood lift, giggly happiness) and deepen progressively into body relaxation with sedation potential that becomes more pronounced at full dose. At moderate doses, it is not a couch-lock strain; at full dose or in high-THC batches, expect genuine weight. Retail batches typically test in the mid-to-high 20s percent THC. Best use window: late afternoon through evening. Read the full RS11 strain spotlight for in-depth coverage.

Zoap: the balanced sibling

Zoap (RS21) is the lighter, more citrus-forward sibling. Where RS11's terpene lead vacillates between Limonene and Caryophyllene by batch, Zoap's Limonene dominance is more consistent — and it runs a third terpene, Linalool, that is unusual for a premium hybrid at this potency. The Limonene + Linalool combination is what creates the strain's defining aroma: a soapy, floral, clean freshness that genuinely resembles expensive hand soap or floral body wash. The name Zoap is a play on "soap" — an accurate descriptor once you experience the profile.

The absence of significant Myrcene or heavy Caryophyllene lead in Zoap's typical COA is what produces its lighter effect arc relative to RS11. Effects open with rapid euphoric mood elevation, giggly social energy, and calm body ease — without the progressive couch-lock potential of RS11 at full dose. At moderate doses, Zoap is functional and social. At higher doses, some body weight develops, but the effect ceiling is lower than RS11's. Retail batches typically test in the mid-to-high 20s percent THC, with premium lots pushing past 27%. Best use window: afternoon to early evening.

Choosing between them: a practical guide

The decision is about three things: desired effect window, aroma preference, and body effect depth.

Choose RS11 if you want significant body ease alongside mood lift, an evening or wind-down strain, a tropical-fruit-and-gas aroma profile, or you are already comfortable with higher-potency indica-leaning strains. RS11 is also the pick for consumers who find Zoap's soapy-floral aroma unfamiliar or unusual — the tropical-fruit-diesel profile is more conventionally cannabis-adjacent.

Choose Zoap if you want a more functional afternoon-to-early-evening window that doesn't shut down the rest of your evening, a genuinely distinctive floral-soapy aroma, or you prefer mood elevation over body weight. Zoap is also worth prioritizing if you haven't tried the Limonene + Linalool combination before — the aroma is one of the most distinctive in the current Vermont market.

The COA is your fastest confirmation tool. On an RS11 batch, look for Limonene and Caryophyllene running close together at the top — either can lead depending on how the cultivar expressed. If Caryophyllene leads clearly, expect more body-forward effects. If Limonene leads clearly, expect a more uplifted, citrus-forward onset with body weight deepening later. On a Zoap batch, Limonene should lead clearly, with Linalool appearing in the named terpene list — that Linalool presence is the marker that explains the soapy-floral character. If your "Zoap" COA shows Myrcene dominant or no Linalool, double-check with the budtender.

Finding RS-line strains at Vermont dispensaries

RS11 is confirmed at Upstate Elevator Supply Co. (699 Pine St, Burlington, VT) in a Living Soil 3.5g format. Living-soil cultivation emphasizes microbiome health and is associated with heightened terpene expression — for a strain where the terpene profile is the primary value, this is a meaningful provenance detail. Upstate Elevator is Burlington's dedicated craft-tier dispensary and a consistent source for premium rotating genetics.

Zoap is confirmed at Theory Wellness (768 Putney Rd, Brattleboro, VT; open daily 9 AM–9 PM). Brattleboro is in southern Vermont, approximately 2.5 hours from Burlington; for Burlington-area consumers, the northern dispensaries are the practical primary option.

For both strains, also check Float On Dispensary (136½ Church St, Burlington) and The High Bar in Essex Junction, both of which rotate premium genetics from Vermont farms and are likely sources as cultivator availability changes. Vermont law requires all dispensary cannabis to be grown in-state by a licensed Vermont cultivator — any RS-line genetics on a shelf come from a Vermont farm, not from California. Digital menus update frequently; check before visiting, or call ahead and describe the strain by name. For RS11, describing the tropical-fruit-plus-diesel aroma to a knowledgeable budtender who has handled it is an effective approach even when it is not currently listed.

Both strains are premium tier — available and rotating, not ubiquitous. When you find them, request the batch COA. Vermont's dispensary transparency requirements make terpene data available at the counter, and for RS-line strains specifically, the terpene panel tells you more about what you are actually getting than any general description can.
