I have enjoyed Mariage Freres teas for over 15 years and this is one of my favorites. As other reviewers noted, it is delicious and aromatic. Only wish it came in the 6 oz loose leaf refill as one can only use so many of the tea tins.
I certainly cannot improve upon Mariage Frère's apt description and can only add that it's almondy/mildly spicy flavor is as exciting as watching the "plein lune".
Pleine Lune is one of my favorite autumn teas. It has a very light spice flavor and the almond gives it a creamy, smooth sweetness. It's not unlike chai tea, but much more subtle and great straight up.
This is my first tea from France and I assure you it is worth every cent. Opening the box and the canister is an experience in of itself. The smell of the tea is delightful, and it never loses that aroma, even after you make a cup. I am not a straight black tea drinker but this one tea I could drink with nothing added to it. It still tastes great even if you add cream/milk and honey/sugar. I highly recommend this tea for people who like very sweet, flavorful, and aromatic teas.
