A pink liquor with ruby glints in a glass carafe: Havana, in the French Summer Tea version, is an iced green tea from Mariage Frères whose colour is noticed before its taste. The tint comes from the hibiscus, which here accompanies a whole-leaf green tea, sunflower petals, pomegranate and goji berries.

The product comes in a glossy black blown glass bottle containing 160 g of tea, with its measuring stopper and a pack of filter sachets. The ingredient list mentions green tea, hibiscus and flavourings; the blend may contain traces of nuts. It appears in the catalogue under the Jardin Premier label.

Cold-brewed, the green tea keeps its vegetal freshness without bitterness. The hibiscus brings a clean acidity, like a lightly sweetened red fruit syrup; the pomegranate and goji berries add a rounder fruitiness, and the whole makes a gentle, tangy, bright drink, very refreshing. It is an iced tea for those who like fruity drinks but avoid sugar.

Use one measuring stopper, or 10 g, in a filter sachet, for 1 to 1.5 litres of pure water, refrigerated for at least one hour. The bottle makes up to 24 litres. Serve over ice, with an orange wedge or a few pomegranate seeds; it goes with a brunch, a summer salad or a fruit platter, and makes a better choice than lemonade at a children’s table.

Infused tea keeps for two days in the refrigerator in a closed bottle. The bottle, stoppered and kept away from light, keeps for the whole season, and the house intends this tea for summer as well as for the rest of the year, served chilled whenever you want colour in the glass.
