Beaujolais
Don't be put off by Beaujolais Nouveau, this region is SO much more than that. Using the Gamay grape, these lighter, lower tannin wines are the gateway wine for white wine drinkers into the wonderful world of reds. Beaujolais Villages are fresh and fruity, but then you have wines such as Fleurie, Morgon and Moulin-a-Vent that are capable of ageing and are really serious wines, albeit, lighter ones. Please give Beaujolais a shot, particularly during the summer months, you won't regret it.
Guy Breton, Chateau des Tours and Du Grappin are some of the producers that I particularly like.
