Roku Gin & Tonic (六ジントニック)

A gin and tonic looks almost too simple to teach, which is why people spoil it. Too much ice melts fast. Warm tonic goes flat. A heavy hand with garnish turns the glass into a fruit bowl with ambitions. Keep it cold, keep it measured, and the drink becomes clear again.

Roku means six, and the gin is built around six wa-botanicals: sakura flower, sakura leaf, sencha, gyokuro, sansho, and yuzu. That is the point of using it. The tonic should lift those botanicals, not bury them under sugar or perfume. We use one large piece of ice because it chills the glass hard and melts slowly, giving the drink time to stay itself.

The deciding detail is the yuzu peel. Pinch it over the finished glass so the oils land on the surface, then set it in lightly or leave it on the rim. Citrus oil sits where your nose meets the drink, and that first breath is half the flavor. Nothing hidden. Just cold glass, clean bitterness, and a small bright edge of the season.
