Boppard is a vintners town and the main reason for this is the Bopparder Hamm, a steeply sloping south-facing hill in the Rhine valley which produces some very fine white Riesling wines. Various estates have vineyards here. The appelation belongs to the Mittelrhein growing region, together with the vineyards around Bacharach lying about 25 kms south. The Mittelrhein used to be quite a good region for purchasing some real bargains, but that is mostly history now. The best producers have earned themselves an international reputation and that has led to higher prices, together with an ever more selective growing method. At least, the quality has also been improved along with the higher prices.
The best estates probably are Weingart and Matthias Müller, both being based in Spay, a village some 3kms away from Boppard. Weingarts makes quite dry superior quality Rieslings which the New York Times has raved about in a recent article. Go for the Kabinett or Spätlese wines, but expect to pay around 10 EUR per bottle. Some Weingart bottles come with an inventive and very classy glass prop sealing instead of the cork. Müller makes some very decent Grauburgunder (Pinot Gris, Pinot Grigio) in addition to slightly cheaper Rieslings starting from 5 EUR/bottle.
Pretty good are the Boppard based estates August & Thomas Perll as well as Königshof. If you would like to try a wine from nearby Bacharach, go for Toni Jost Standard Quality Rieslings will start at about 5 EUR, the Predicate wines around 8-10 EUR.
Nearly all the wines from this interesting region can be sampled locally at the Bopparder Weinkontor.
Whatever you do, don't miss a boat trip on the Rhine. Bear in mind that because of water levels, the cruise liners and sightseeing boats only start their season in late March/early April. Once you are aware of this you have loads of alternatives. Here is a photo of the famous Loreley cliff where many a sailor is said to have drowned. More because of the difficult navigation through the river bend here than because of the old Loreley legend...There are many cliffs just like it along the Rhine but this one has a viewpoint on top too (get there from St Goarshausen) so I suppose it will always stay as peoples' favourite dramatic cliff.
Fondest memory: I love the way you can just sit and observe the river life and barges from beer gardens everywhere.
