Cardamom, clove, citrus and oolong tea make the chai character of Rutland Square feel structured and dry rather than merely perfumed. The recipe brings together juniper, coriander, cloves, cardamom, lemon, cinnamon, orange, black pepper, caraway seeds, star anise, oolong white tea and vetiver. That list explains the style clearly: citrus keeps the gin lifted, tea gives it a dry tannic thread, and the spice blend adds warmth without relying on sweetness to make an impact.

The nose opens on orange zest, lemon peel and sweet spice. Cardamom and cinnamon arrive early, but the oolong note is important because it prevents the gin from becoming heavy. It gives the aroma a drier, more textured side, closer to steeped tea than dessert spice. On the palate, juniper and coriander remain visible beneath the chai profile. Clove, star anise and black pepper add grip, while vetiver brings an earthy base that makes the finish longer and more grown-up.

The many spices remain remarkably composed. Chai can easily become too round or too perfumed in a spirit, yet here the citrus and tea keep the drink agile. The 41% ABV gives enough structure for tonic without making the spices sharp. Its profile suits drinkers who enjoy aromatic gins, winter serves or cocktails that can carry warmth without losing freshness. It is not just a novelty flavour; it has a clear botanical architecture.

For the Perfect Serve, Indian tonic, clear ice, orange peel and star anise make sense. Orange repeats the bright top note, star anise underlines the chai character, and the tonic adds bitterness that keeps the drink dry. One star anise is enough. With too much garnish, the balance would move away from the gin and toward mulled-spice territory, which would obscure the clarity of the gin.
