Le Marais is the original and heart quarter of Mariage Frères, and the house dedicates to it this blue tea with a sensual fragrance of red berries and cinnamon, as a tribute to its creativity: its lively streets, its secret gardens, its lovers and its fashionistas keeping up with the latest trends. Marais in Love belongs to the In Love collection, whose signature is rose petals.

Blue tea, or oolong, is a semi-oxidised leaf, between green and black, with a velvety texture and a naturally floral aroma. Here it welcomes red berries and cinnamon with a softness that black tea would not have. The composition combines tea, rose petals, blue flowers and flavouring; the blend may contain traces of tree nuts.

It comes in a turquoise blue box accented with gold, containing 30 traditional round cotton muslin tea sachets, net weight 75 g. One cotton muslin tea sachet, one 200 ml cup, five minutes, and Marais is served.

In the cup, the liquor brews its pretty golden, fruity and exuberant hues, the house says. Red berries open, fresh and slightly tart, then the cinnamon warms the palate without stinging, the rose slips in behind, and the blue tea rounds it all off with a silky texture. It is an afternoon tea, low in caffeine, best drunk plain. It pairs well with a red berry tart, macarons, cinnamon biscuits, or an afternoon snack with friends. Served iced, it keeps its sweetness and gains freshness.

Allow one cotton muslin tea sachet per 200 ml of water at 95°C and five minutes of steeping; the blue tea leaf needs this time to open. The box should be kept closed, away from light and strong odours. For a teapot, allow one cotton muslin tea sachet per cup.
