Off hand I know Bertheau has only made a red…and Raveneau has only made a white. Name some producers that have NEVER deviated from only doing a red or white wine? I’m only thinking Burgundy here btw.
Buzz, I assume you are talking commerical releases over a certain number of cases? My guess is a lot of producers have “made” wine of both colors, but it may not be enough wine, nor worth, releasing to the public.
Also, if you’re considering Chablis to be part of Burgundy, then I’d imagine there are a number of producers who have only released white wines. There just isn’t that much red grown there.
