Terpenes that test highest: limonene, caryophyllene, humulene (from 26 tests)
Most of these tests come from one producer, so they may say more about that grower than the strain.
This is a small number of tests, so treat the range as rough.
Flower tested under this name in legal US markets, 2020–2025. The range covers the middle 90% of tests. Growers and labs vary, so a given jar can fall outside it. Data: Jikomes & Zoorob (CC0), Cannabis Wise Guys (CC BY 4.0), Cannlytics (CC BY 4.0).
About Grape Jelly
Grape Jelly is a hybrid cross combining Island Sweet Skunk and NYC Diesel. Known for grape, lavender, sweet aromatics.
In grower catalogs and dispensary menus, Grape Jelly (also circulated as Grape Jam) is documented as a hybrid cross combining Island Sweet Skunk and NYC Diesel. State lab records track Grape Jelly across 3 legal markets between 2020 and 2025, with a large share of tested flower batches originating from a single regional cultivator. Photoperiod cuts typically finish flowering in 8–10 weeks (~56–70 days) under indoor or greenhouse lighting.
Aroma and flavor
Jars of Grape Jelly are most often described as showing candied dark grape, calming lavender, sweet, sugary notes and creamy vanilla bean. Across state lab terpene panels, bright, citrus-forward limonene, peppery beta-caryophyllene and woody, hop-like humulene most frequently test at the top of the profile, though cure quality and phenotype selection shape how loudly each note comes through.
Reported effects
Consumers commonly report warm physical comfort, clear-headed task focus and an upbeat, cheerful mood, making Grape Jelly a frequent pick for late-afternoon or flexible social and evening use. The most commonly noted downsides are dry mouth and nervousness if overconsumed.
