Summer in Paris, the light on the cobblestones, a stroll along the Seine: Mariage Frères, born in Paris on 1 June 1854, has turned this city into an iced tea. Paris Summer is a green tea from the French Summer Tea collection, made for cold infusion, in a black glass bottle where blue, white and red ribbons and an Eiffel Tower ripple.

The green tea is flavoured with yuzu, with its Japanese citrus brightness, mint, with its caressing freshness, and a green bergamot with vibrant notes, enriched with rose petals. The ingredients are tea, yuzu, rose, mint and a flavouring; the blend may contain traces of nuts.

Cold infusion draws the flavours from the leaves without their tannins. The iced liquor is lively and fresh: the yuzu opens, the mint refreshes, the green bergamot gives tension, and the rose softens the finish. No sugar is needed, the roundness of green tea is enough.

It is served in a jug, at the table, all afternoon on a hot day, with a summer meal, a salad, grilled fish, or a citrus pastry. Prepared the evening before, it is ready on waking, and keeps two or three days in a cool place.

Preparation takes three steps: one measuring cap of tea, about 10 g, into a filter envelope; the flaps closed; at least one hour in the refrigerator in 1 to 1.5 litres of pure water. The bottle of shiny black blown glass, with its measuring cap, contains 160 g of tea, enough to prepare up to 24 litres, and it is delivered with a packet of filter envelopes.
