The following should enable you to find and order most of the major German beer
styles in the UK. Always check the current stock position, which tends to
fluctuate, and confirm the delivery charges involved.
A good starting point is
Beers of Europe, a Kings Lynn-based
company, who offer a good Internet service with reasonable shipping charges and
have a very large range of German beers in their catalogue (around 200, with
over 60 breweries represented), along with beers from many other countries.
Only Fine Beer reckon to offer about 130
German beers but their price per bottle is higher, as are their delivery
The Offie has an interesting range of German beers, totalling
over 30 when I checked
Easy Wine offers only about a dozen beers in all, but there are
two or three interesting German and Belgian ones among them.
