As a rule, chocolate is considered to be a "wine enemy", which means that one has to be particularly careful when choosing a wine to go with it or, in extreme cases, that chocolate does not go at all with certain types of wine due to taste disharmonies (see Wine with Food for more details). The fact that "wine & chocolate" are considered incompatible in this country is due to the preference for sweet milk chocolate in Germany and Austria. With bitter chocolate, on the other hand, there are many more possible combinations. There are a few basic rules for choosing the right chocolate and wine. The most important is: only high-quality chocolate and fine wines go together.
There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.Sigi Hiss
