In keeping with the local tradition of clandestine La Bleue, Kubler is crystal clear, has no added sugar and is finished at 53% alcohol. It is very aromatic and has a deep white louche, which, in contrast to its French counterparts in Pontarlier, is brought on by a judicious use of star-anise in the formula. This absinthe is already the best-seller in Switzerland and is getting much international attention and praise.
