Lycium ruthenicum
Small dried berries that bleed a deep violet-blue into water and shift towards pink with a squeeze of lemon.
Botanical story · current research
Black goji is a thorny shrub adapted to dry, high-altitude landscapes of Central Asia and western China. Its small dark berries contain abundant anthocyanin pigments, which move through blue, violet and pink tones as the acidity of the water changes. The flavour is mild and lightly fruity, allowing colour and the delicate whole berry to remain the focus.
Lycium ruthenicum
Central Asia & western China
Lycium ruthenicum grows in demanding saline and desert-edge environments, where the berries have traditionally been gathered as a valued regional food. Today they are often prepared in clear glassware so the release of colour becomes part of the serving ritual. A few berries in water create a quieter, less floral counterpart to butterfly pea’s colour-changing theatre.
Berry · whole dried fruit
The berries are usually dried whole, protecting the pigments until water reaches the skin. They may be gently infused, added to a cold carafe or used as an edible garnish after steeping; crushing releases colour faster but also changes clarity and texture. This profile follows the whole berry rather than treating every serving method as a separate product.

How to prepare
Use 15–20 berries per 250 ml of water at about 80 °C — hotter water dulls the colour.
Let them stand 5 minutes; the blue develops gradually as the berries rehydrate.
Add lemon at the table to turn the infusion violet-pink, or leave it as it is.
