Appearance

Star Pupil buds are notably dense and heavily coated in resin, often displaying deep purple, violet, and blackcurrant hues marbled throughout. Contrasting orange-to-copper pistils stand out against the dark calyxes, while a dense layer of trichomes imparts a silvery sheen. Some phenotypes exhibit a distinctive "zebra striping" pattern on the bracts and sugar leaves, a trait enhanced by cooler temperatures and balanced nutrition. The flowers typically present tight calyx stacking and a sticky texture, contributing to their gem-like appearance.

Aroma & Flavor

The aroma of Star Pupil is a rich tapestry of grape skin, wild berries, and a peppery, incense-like spice, often accompanied by notes of black tea, dried rose, and citrus rind. Upon consumption, flavors commonly lead with blackberry jam and concord grape, complemented by black pepper, clove, and sandalwood. Phenotypes may also offer hints of lemon peel or orange oil, particularly on the exhale. The flavor profile is complex, balancing fruity sweetness with a sophisticated, spicy finish.
