Biscotti x Sherb BX1

Lineage & Genetics

Cross: Biscotti S1 x Sherb BX1

Biscotti, the seed parent, is the Cookie Fam cut widely attributed to Jigga and Mr. Sherbinski, bred from South Florida OG x Gelato #25 per SeedFinder. Leafly reports that JBeezy reversed that clone into Biscotti S1 seed and selected a high-potency, gas-forward plant from it. What Biscotti brings is chemistry and density: a heavy base of caryophyllene, limonene and myrcene reading as cookie-dough sweetness over sharp diesel, black pepper and earthy hash, carried on compact golf-ball bud formations with dark forest-green to near-violet calyxes and very high trichome retention. On the effect side Biscotti is the sedative half — heavy body pressure, weighted eyelids and couchlock that slows down the faster Sherbert onset. Sherb BX1, the pollen parent, is Seed Junky's own work: SeedFinder records it as Sunset Sherbert x (Sunset Sherbert x Animal Cookies Bx2), a backcross JBeezy built specifically to fix the original clone-only Sunset Sherbert's weak, floppy branching and modest yield. Folding in Animal Cookies stiffened the lateral stems, tightened node spacing and added biomass while keeping the anthocyanin purple expression intact. Aromatically it pushes the bright monoterpene side — limonene, linalool and caryophyllene giving creamy citrus sorbet, sweet tart berry and floral gas — and on effect it supplies the early euphoric, mood-lifting headspace. Notably, the same Sherb BX1 male had already produced Jealousy when crossed to Gelato #41, which is why Jealousy and this cross share half their ancestry and why the Permanent Marker pedigree doubles up on Sherbert. A useful way to hold it: Biscotti set the resin, density and weight; Sherb BX1 fixed the structure, color and the sweet-citrus top note; and the volatile solvent funk that later became Permanent Marker's signature marker-fume nose was reported to emerge from the combination of the two.

Terpene Profile

Aroma: No cured flower has ever been sold or reviewed under this name, so the aroma described in the research is reconstructed from the two parents and from the progeny the cross produced. In that account the jar nose unites heavy pungent pastry dough and burnt-rubber gas from the Biscotti side with candied citrus peel and creamy sweet berry from Sherb BX1. The detail worth knowing is what happens on the break: when buds are cracked or ground, an intense solvent-like chemical undertone comes forward, and Beard Bros Pharms reports that JBeezy and Doja Pak identified exactly this volatile note as the precursor to Permanent Marker's unmistakable industrial felt-tip marker fume. In other words, the marker smell that made Permanent Marker famous was already latent in the mother.

Flavor: Again parent- and progeny-derived rather than tasted and documented under this name. The inhale is reported as smooth, thick and velvety, carrying sweet vanilla cookie dough, spiced nutty pastry and sour citrus cream. The exhale flips sharply into expansive gas, pungent diesel and peppery earth, and the aftertaste coats the palate with sweet tart confection, a soapy lavender edge and heavy fuel that stays noticeable for several minutes after the smoke clears.

Effects & Experience

Onset: Very rapid, reported at roughly 2 to 5 minutes, beginning as warm pressure behind the eyes with a mild cerebral tingle. Derived from parent and progeny reports, not from documented consumption of this unreleased cross.

The described arc is a two-stage one that mirrors the pedigree. It opens with a rush of giddy euphoria and mental relaxation attributed to the limonene and linalool coming off the Sherb BX1 side, then within about 20 to 30 minutes the Biscotti and South Florida OG heritage takes over, washing down the neck and spine into a heavy, warm, gravitational full-body weight. At higher doses that resolves into significant couchlock and deep tranquilization rather than raciness. Reported drawbacks in this family are pronounced dry mouth and dry eyes, daytime lethargy, and dizziness or immobility in low-tolerance consumers given how high the cannabinoid content runs in selected phenotypes. All of this is inferred from the parents and from released progeny; no consumer ever had flower from this plant.

Duration: Long, typically reported as 2.5 to 3.5 hours in progeny selections.

Grower's Notes

History & Origin

The line starts with a male. Through 2018 and 2019 JBeezy was working heavily with his own Sherb BX1 pollen donor, which had already produced Jealousy when crossed to Gelato #41. Looking to push further into hyper-refined dessert-gas territory, he reversed the Cookie Fam Biscotti cut into Biscotti S1 seed, popped it, and crossed a selected Biscotti S1 female to the Sherb BX1 male — the work is placed in Southern California, with Leafly's account putting it around 2018–2020 and Beard Bros Pharms placing the breeding between 2019 and 2021. From that population JBeezy pulled a single standout keeper female that combined gassy dough, heavy purple pigmentation and dark candy tones. That female is the plant this page is about, and it was never released: no source shows it packaged as seed, cataloged, or distributed as a verified clone. It stayed inside Seed Junky's licensed facilities as proprietary breeding stock. He then pollinated the keeper with a Jealousy F2 male and shared the resulting seed with Doja Exclusive — Doja Pak, Ryan Bartholomew — who hunted it collaboratively. The cut that came out of that hunt was named Permanent Marker for its pungent synthetic marker-fume nose; it dropped in 2022 as limited clone releases reportedly fetching up to $1,000 a cutting and was crowned Leafly Strain of the Year for 2023. Leafly's Strain of the Year roundup describes Adios MF and Gunnpowwder as sister phenotypes from the same (Biscotti x Sherb BX1) x Jealousy F2 seeds, with Gunnpowwder selected by Berner for the Cookies brand Minntz, although Leafly's genealogy article loosely lists both names as aliases of Permanent Marker. Other phenotypes genuinely selected out of the same seed batch were branded separately, including Purple Octane, kept by Seed Junky for its darker grape-candy gas and heavy purple expression, and Diesel Dough, which reached regulated medical and adult-use markets. Separately, Seed Junky kept reaching for the same maternal block in its catalog work, pairing it with Face Mints, Pineapple Fruz, Banana Cream Cake, Zkittlez and Bubblegum Sherb. That is the reason an unreleased plant is worth documenting at all: it is the shared ancestor sitting one generation upstream of a whole cluster of releases that are usually discussed as if they were unrelated.
