Grape Stomper Strain: Everything You Need to Know

The Grape Stomper strain is a sativa-leaning hybrid from Gage Green Genetics, built for one thing: grape-candy sweetness over sour diesel funk. You may also know it as the Sour Grapes strain, a second name it picked up after the cut was sold to a California collective. Both names have circulated ever since.

The Grape Stomper strain genetics come from Gage Green, which crossed JojoRizo’s Purple Elephant with an Elite Seeds Chemdog Sour Diesel cut. The Purple Elephant side brings the grape. The diesel side brings the funk and vigor. The result is one of the more distinctive flavor profiles out there, sweet and savory at the same time.

This Grape Stomper weed strain never fully went mainstream, which is part of why collectors hunt for it. With THC reported anywhere from the high teens to the high 20s, the Grape Stomper strain effects are known for a euphoric, mood-lifting start backed by a warm, grounded body feel.

Here’s what’s in the jar, and what’s worth knowing before you buy or grow it.

If you want the cheat sheet before the deep dive, here it is:

• Strain type: sativa-leaning hybrid
• Genetics: Purple Elephant x Chemdog Sour Diesel
• Breeder: Gage Green Genetics
• THC: commonly in the high teens to high 20s; thisthat’s batch tests at 29.542% THCA and 26.152% total THC
• CBD: trace levels, around 0.05% in thisthat’s batch
• Terpene profile: caryophyllene, limonene, myrcene, humulene, linalool
• Aroma/flavor: grape candy, citrus, sour diesel, and black pepper
• Effects: euphoric, uplifted, warm, relaxed, and versatile

The Grape Stomper terpenes include caryophyllene, limonene, myrcene, humulene, and linalool, with 2.440% total terpenes in thisthat’s batch below.

Caryophyllene: This is the star, making up about a third of the batch’s terpene profile. Caryophyllene is the same peppery, spicy compound found in black pepper and cloves. Here, it adds a black-pepper edge that cuts through the sweetness.

Limonene: Limonene brightens the top with citrus. It’s commonly linked to mood elevation, which fits the euphoric start of the Grape Stomper strain effects.

Myrcene: Myrcene adds an earthy base and is commonly associated with relaxing body effects.

Humulene: Humulene brings earthy, woody, slightly hoppy notes that deepen the savory side.

Linalool: Also found in lavender, linalool adds a soft floral note. Research suggests linalool may help promote calm.

Smaller amounts of bisabolol and guaiol round out the exhale with a warm, spicy-floral finish. The grape itself comes from the Purple Elephant side, while the sour fuel traces back to the diesel parent. That’s why the Grape Stomper strain flavor lands sweet grape and citrus first, then sour fuel and pepper, then a warm floral exhale.

Grape Stomper terpenes can shift from grower to grower. Other published profiles lean more on myrcene, limonene, and terpinolene, so check the COA for the batch you’re buying.

But on a second session, vaping it at 392°F, they found it calm, euphoric, and creative.

Over in r/NYSCannabis, a Grape Stomper strain review covered Doobie Labs’ Grape Stomper, which had 2.8% terpenes. They described the smell as “grape diesel” and loved it.

They called the Grape Stomper strain effects a solid sativa experience, starting in the head before settling into a mild body high.

One reviewer gave it 4/5, saying it lifted their mood with a mild boost of energy. Another described lime green buds with fiery red hairs and a sweet, sour, tropical nose.
