In Berlin, the classic is Wein und Glas, with a full online list of wines, to make advance prep easy.
The 'natural' star is Viniculture. Lots of good names and not too esoteric on the natural front. The online list typically doesn't reflect the bottles available in the store, but you can see the list of winemakers they carry.
I also really like Heimat Wein for a more old-fashioned owner/proprietor feel with a mix of new and old names. But the website is unhelpful, it's less centrally-located, and the owner Nico may not speak much English and is not always there. But he's still my favorite!
