I think I will be able to do the changes next weekend.
If no one objects until Friday, I'll assume that everyone is fine with the changes as proposed in this thread.
I'll furthermore assume that I can modify the descriptions of categories as I see fit (I explained in a previous mail on this topic on how those could be made to convey more exactly which parts of wine they cover).
I just saw that there still are overlaping categories in at least one case, but that can be fixed in another step.
