Legrand Filles & Fils is one of the many very interesting wine shops you can find in Paris. It is definitely worth a visit if you are looking for some interesting bottles to carry home. In addition they have a wine bar and serves lunch if you are hungry. They regularly hold tastings and have a series they call “Tuesday wine tastings”.
Recently they published the autumn program that includes for example Chateau Pontet Canet, Champagne Tarlant and several other interesting tastings. Read more about their program here: Wine tastings at Cave Legrand wine shop in Paris
