A bottle of blown glass in glossy black, a measuring cap, a sachet of filter envelopes: Hawaii Kawaii is designed for iced tea, and for nothing else. It belongs to the French Summer Tea collection by Mariage Frères, and its very kawaii graphic design, in the house’s words, makes it a summer object to place on the table.

The base is a red rooibos, a plant from South Africa that is not a tea and contains no caffeine. The house blends it with hibiscus flowers and a flavouring with notes of pineapple and red fruits; the full list of ingredients is printed on the bottle and on this sheet. The taste, says Mariage Frères, is that of a Hawaiian holiday: fruity, sweet, exotic.

Infusion is made cold, and that is what makes the cup. The rooibos gives its sweet softness and red colour, the hibiscus a tangy edge, the pineapple and red fruits the indulgence. The result is a fresh drink, without bitterness, to be drunk in a glass, with ice, without added sugar.

Preparation takes three steps: place one measuring cap, or 10 g, in a filter sachet; close the flaps; leave to infuse in 1 to 1.5 litres of pure water, in the refrigerator, for at least 1 hour. The bottle holds 160 g, enough to prepare up to 24 litres of iced tea through the summer.

The blend may contain traces of nuts. Hawaii Kawaii is available at La Boutique du Thé, official Mariage Frères stockist since 1999, in Bordeaux and Nice. Keep the bottle closed, away from light and heat, and prepare your jugs the day before.
