Any German beer from Aldi/Lidl brewed in accordance with the purity laws.
I'll say! I was amazed at how good that stuff, is for the price! People pay 3 times as much, for lesser beer.
On the subject of German beer, I'm a bit of a wheat beer fan. Weihenstephaner (the Kristalweissbier is amazing; hint of pear-drops about it), Franziskaner, Erdinger, Schneiderweisse, and Paulaner are brands you might find in a supermarket, and Waitrose in London often stock Meantime beers; they do a Weisse bier, and one of my absolute favourites; Raspberry wheat beer. Much nicer than it sounds, it is actually quite sharp, not too sweet, like that Fruili muck. Waitrose also do their own-branded (German brewed) wheat beer, in light and 'Dunkel' versions. One or two other brands, including a Corsican wheat beer, Colomba, as well as the ubiquitous Hoegaarden (the Stella of the wheat beer world), and Kronenbourg White, which is ok in small amounts. Can't drink too many pints of that one, as I find it a bit sickly, after 2 or 3.
