Chartreuse (liqueur) was not a secret but well known. At the death of the pharmacist, his heirs returned the manuscript to the monks who had been back at the Monastery since 1816. In 1838, they developed Yellow Chartreuse, a sweeter version of the Green Chartreuse, 40% alcohol liqueur (80° proof). The monks were again expelled from the monastery following a French law in 1903, and their real property, including the distillery, was confiscated by the government. The monks took their secret recipe to their refuge in Tarragona, Catalonia, and began producing their liqueurs with the same label, but with an additional label
Navan liqueur Navan liqueur Navan (nah-váhn), is a vanilla liqueur produced by the House of Grand Marnier. Navan's name stands for "Natural Vanilla". The vanilla beans are imported from Madagascar. Alexandra Marnier Lapostolle, current president of Marnier-Lapostolle North America and creator of Casa Lapostolle Wines, chose the natural vanilla flavor to create Navan, a new liqueur founded on Grand Marnier's success. Navan launched in 2004 in the USA, where it is distributed by Moet Hennessy USA. It is also available in Canada and the Caribbean. In 2008 Navan introduced a revised, less sweet formula, based on feedback from bartenders and chefs. By
