We got drunk on that stuff as students because we didn't know any better and had no money. That is not what I would say, at least not in public, but it summarises how many British acquaintances refer to German wine - in particular the dreaded Liebfraumilch. German wine is associated with sweet, and sweet with bad. The British wine trade tend to love Riesling, dry or sweet, and some also appreciate German Pinot Noir. This is usually where the knowledge ends though. There are even "wine experts" who say Germany should not move away from the sweeter style of Riesling - whereas the reality is that the German wine industry has become so diverse it has long gone beyond that. German dry wines are now so varied as would confuse even the most sober foreign beholder.
Last week the German Wine Agencies, a new distributor of German wines in the British market, invited members of the trade to be confused (and to leave everything else but sober, one would hope) by German wines.
