MAC Stomper

Also known as: M.A.C. Stomper

Breeder: Capulator

Lineage & Genetics

Cross: MAC 1 x Grape Stomper

MAC (Miracle Alien Cookies) is Capulator's signature creation—Alien Cookies x (Colombian x Starfighter)—famous for its citrus-cookie fuel bouquet and extreme trichome density. Grape Stomper OG is a cross of Grape Stomper (Purple Elephant x Chemdog Sour Diesel) and Underdawg OG (Headband x Sour Diesel), contributing grape-forward terpenes, sour citrus brightness, and vigorous structure.

Terpene Profile

Aroma: Opens with vanilla shortbread and powdered sugar sweetness from the MAC side, layered over tangy grape peel and orange zest. Beneath the candy top notes sits a warm, peppered, kush-like spice and deep earthy base that reviewers compare to old-school hash. Grinding releases a volatile burst of bright citrus and pine that settles into a spicy-sweet lingering nose. The Highest Critic noted the unmistakable MAC aroma with added hints of berries, lemon, and a musty earthiness.

Flavor: Initial draws are sweet-forward—vanilla-graham cracker, soft grape skin, and lemon cream coat the palate. Exhales shift to orange-lime zest and light pine before resolving into a warm, toasty, pepper-spice finish. As the session progresses, grape notes intensify into a grape-soda quality. Vaporization at lower temps (350–375 °F) accentuates limonene brightness; higher temps push the caryophyllene spice and caramelized sugar. In fresh-frozen rosin, hashmakers report a syrupy mid-palate and lingering bakery finish.

Effects & Experience

Onset: Arrives within minutes when inhaled, beginning as a mild cerebral lift with limonene-pinene brightness—mood elevated, internal monologue quiets.

Transitions from an uplifting, lightly euphoric head high into a grounded, tranquil body calm. Lower doses keep the experience functional and conversational; heavier consumption tips toward couch-lock and time dilation. The Highest Critic described it as a gentle head high that transforms into a stimulating cerebral buzz before settling into a mellow, relaxing body high.

Duration: 2–3 hours for most users, with peak effects at 20–30 minutes.

Growing Characteristics

Grow Tips: Top at the 5th or 6th node, then LST to build 8–16 main tops in 5-gallon containers. Moderate defoliation at day 21 and day 42 of flower improves airflow and reduces botrytis risk in dense colas. Drop temps to 65–68 °F in final two weeks to bring out anthocyanin purple hues and tighten buds. Supplement calcium (100–150 ppm) and magnesium (40–60 ppm) under LED, especially in coco. Target 1,000–1,200 PPFD in flower with CO2; cap at 900–1,000 PPFD without CO2 to avoid photoinhibition. Dry low and slow at 60–62 °F / 55–60% RH to preserve monoterpenes and the candy-bakery nose. Dense trichome coverage makes this an excellent hash/rosin candidate—fresh-freeze for best solventless results.

History & Origin

Capulator rose to prominence after stabilizing Miracle Alien Cookies (M.A.C.), one of the most sought-after cultivars of the modern era. MAC Stomper extends that lineage toward a more indica expression with Grape Stomper influence, targeting heavier resin production, denser structure, and a grape-citrus terpene overlay. The cultivar's rollout relied on selective distribution of regular (non-feminized) seeds rather than mass-market release, fostering scarcity and hype in craft circles. By the early 2020s its reputation was cemented among connoisseur communities, and its consistent trait transmission made it a go-to parent for third-party breeders.
