A measuring stopper for tea, a filter envelope, one to one and a half litres of pure water, and a night in the refrigerator: that is the entire preparation of Tokyo Mojito. No hot water, no teapot. Cold infusion, for a minimum of one hour, draws out the fragrance without the tannins, and yields a clear, thirst-quenching iced tea.

Mariage Frères has composed this green tea from its French Summer Tea collection around yuzu from Japan, that citrus between lemon and mandarin, enriched with hints of mint and lime, in the spirit of an alcohol-free cocktail. The declared ingredients are yuzu tea from Japan and aroma; the blend may contain traces of nuts.

The bottle is in shiny black blown glass, 175 mm high, decorated with a design in which the sun takes the shape of a citrus slice. It contains 160 g of tea and its 10 g measuring stopper, with a pack of filter envelopes, enough to prepare up to 24 litres of iced tea. Preparation takes three steps: a measure of tea in a filter envelope, the flaps closed, the envelope in water in the refrigerator.

The liquor is clear, lively and minty. The yuzu leads, zesty and fresh, the lime extends it, the mint brings the freshness of a mojito, and the green tea stays light, without bitterness, thanks to the cold. Served well chilled, with a slice of lime and a few fresh mint leaves, it carries an entire summer lunch.

Allow 10 g for 1 to 1.5 litres of water, and at least one hour in the refrigerator; the iced tea keeps for two days in a cool place. The bottle, tightly closed, preserves the fragrance of the dry leaf all summer. La Boutique du Thé has been an official Mariage Frères stockist since 1999.
