I have 224 ratings from those two regions: 80 are beers, 144 are ciders, ice ciders and meads
So I second the suggestion about trying ciders, and meads.
Given that I don’t know if they are open to the public and allow tastings, La Cave du Dragon Rouge
(Bretagne) produces very unique ones, long aged in wood, and quite dry.
(Nord-Pas-de-Calais, on your way to Belgium) produces the best French ones.
has some interesting beer (Grand Cru and an IPA).
If you can stand thick beers, I suggest you to get 3 bottles of Samhain XI.I
, one to drink now, one in a couple of years, and the third one after many years.
From there, all other beers in those regions were forgettable.
