Sin Mintz

Lineage & Genetics

Cross: Zkittlez x SinMint Cookies

SinMint Cookies is Sin City Seeds' own in-house line, a Forum Cut GSC (the Thin Mint phenotype) crossed to their Blue Power — Sin City announced the project on THCFarmer in those words. Its breeder listing gives 60 to 65 days of flowering, a 60/40 indica split, 200 to 400 grams per square meter (Leafly says 300 to 500), and a flavor described as cookie dough with mint and kush overtones; Leafly's certified-lab data puts caryophyllene first, then limonene, then humulene, with mint, menthol and nutty as top flavors. Sin City's owner has written that it was a High Times Top Ten Strain of the Year in 2014, but that claim appears only in the breeder's own retailer blog post, so it is breeder-claimed rather than independently verified. The same line is a parent of Seed Junky's Animal Mints and so feeds into the Kush Mints wave and Animal Face — which is what makes Toad Venom a partial line-cross. On the Sin Mintz side, SinMint Cookies plausibly supplies the cookie-dough and gassy kush base: the Tenerife review notes a slightly gassy, cake-like undertone and the Washington grower Subdued Excitement describes a classic cookies taste. The Zkittlez used is the 3rd Gen Family / Terp Hogz cut, Grape Ape x Grapefruit x an undisclosed third strain, renamed The Original Z in 2023 as part of a trademark settlement; it took 1st place at the 2016 Emerald Cup along with Cannabis Cup placings in San Francisco and Michigan, and Leafly's lab data puts caryophyllene first, then linalool, then humulene, with grapefruit, grape and berry as top flavors over medium-sized, spongy green colas at eight to ten weeks. Zkittlez plausibly supplies the candy, grapefruit and tropical-fruit top notes — the Tenerife reviewer called the plant really Zkittlez-dominant with the zingy sweet grapefruit typical of the Z, and Subdued Excitement describes a sweet Zkittlez finish. All of these are parent-derived expectations: none is a verified Sin Mintz trait unless it was independently observed in Sin Mintz itself, and no purple color, bud structure or terpene is inferred here from a parent name.

Terpene Profile

Aroma: Two independent first-hand sources agree on the shape of the nose, and neither of them mentions mint despite the name. The 2021 review of The Italian Artisan's Tenerife phenotype scored smell 9/10 and called it really Zkittlez-dominant — a zingy, sweet grapefruit aroma mixed with slightly gassy terps, comparable to a Blue Zushi or a similar Californian Zkittlez cross. Subdued Excitement, the Washington producer who grew and sold it, frames the same profile from the other side, leading with classic cookies and finishing sweet and Zkittlez-like. How much actual mint expresses in Sin Mintz is unverified: no strain-specific source reports it. On intensity, the only anecdote in the record comes from NuggNotes relaying Jake's story of carrying about four grams of flower from standout plants of this line out of Battleground, Washington during the COVID era — the smell reportedly escaped the overhead bin strongly enough that a flight attendant threatened to ground the plane. That is a story told by an interested party, not a measurement.

Flavor: The Tenerife phenotype scored taste 10/10 and was described as super clean and sweet, with really fruity Z terps carrying an ever-so-slight gassy, cake-like undertone. Subdued Excitement describes the same pairing in the opposite order: a classic cookies taste with a sweet Zkittlez finish. Across both sources the consistent read is sweet Zkittlez candy and grapefruit riding over a cookie, cake or light-gas base. Both accounts are single-grower descriptions of individual phenotypes from a regular-seed population, so flavor expression across a pack is undocumented, and the degree of mint — the part the name would imply — is unverified.

Effects & Experience

Onset: Undocumented. No source describes onset speed or the arc of the first few minutes for Sin Mintz, and no COA or lab potency data exists to anchor an expectation.

One published report exists. The 2021 Tenerife review scored effects 8/10 and described it as for sure not an absolute knockout tackle but very high in THC — a nice all-round relaxing high that did not cloud the mind much or bring lazy side effects. That is a single grower's account of a single phenotype and should be read as such. StrainCompass lists 20.6 to 24.1% THC and 0.6% CBD, but it names no underlying lab or COA, so those numbers are unverified. Claims elsewhere that the Sin Mintz side makes Toad Venom paralytic describe Toad Venom, not this plant, and are not carried over here.

Duration: Undocumented. No source gives a duration for Sin Mintz.

Grower's Notes

History & Origin

Sin City Seeds was founded in Las Vegas in 2010, with owner and head breeder known as Don. Its Blue Power line underpins SinMint Cookies, which Sin City announced on THCFarmer as a project crossing the Forum Cut GSC (aka Thin Mint) to their Blue Power. Sin Mintz — the Zkittlez cross of that line — has no public release date; Sin City never dated it. What can be pinned down is that it existed by late 2020, because NuggNotes reports that seeds from Animal Face crossed to a selected Sinmintz male had been produced by then, and it was grown and reviewed as finished flower in Tenerife by July 2021. Its route into the modern hype cycle runs through Toad Venom. Per NuggNotes, citing Jake (co-owner of Ronin Seeds, then associated with West Coast Connoisseurs), standout phenotypes of this line grown in Battleground, Washington convinced him the genetics were special; 805 Has Fire worked the males while Ronin Seeds and Cannapy Builders supplied females, and one male that survived being snapped in half during a move became the Sinmint F1 male. Animal Face crossed to that male was in seed by late 2020, and the seeds went out to hunters the following year. NuggNotes adds that Ronin was never built as a traditional retail seed company — its purpose was to supply selected genetics to cultivation partners. Green Dragon (North Hollywood, with the hunt also placed at its Cathedral City facility) popped about 30 Sin Mintz x Animal Face seeds and kept one plant, named Becky. The date of that hunt is genuinely in conflict: GreenState, Newsweed and NuggNotes all place it in 2021, while Leaf Magazine says 2022, and nothing in the record resolves it. The cut reached Ronin's Oklahoma grow and was renamed Toad Venom, a name that came out of the question what is a sinful animal; Green Dragon says the cut left its facility without authorization. Everything after that concerns Toad Venom rather than Sin Mintz itself: frog-head packaging at Spannabis 2024; Jake's account of deliberately releasing fake cuts, including one he says was Detroit Runtz, during an Oklahoma business dispute; the Mango After Hours episode The Truth About Toad Venom featuring Ronin Seeds and Green Dragon, dated February 13, 2026 by GreenState and listed as February 23, 2026 on Listen Notes; GreenState calling it 2026's hottest strain; competing clone drops in May 2026, with Ronin releasing 200 clones on May 10 at Goat Global and Green Dragon releasing several hundred on May 17; and High Times naming it a June 2026 Strain of the Month, describing it as Sin Mintz x Animal Face — that is, Sin Mint Cookies x Z with extra gas. Sin Mintz's own market footprint stayed small by comparison: regular seed packs of 7 or 15 from the Sin City shop and from independent banks such as Heritage Seed Bank and Terpy Seeds, one licensed Washington producer (Subdued Excitement, an I-502 producer-processor in Ferndale/Bellingham) selling it as flower, and one reviewed European phenotype grown by The Italian Artisan in Tenerife.
