Interspar - Feldkirch Altenstadt

Big supermarket with a good selection of mass produced Austrian and some German beers, as well as some local beers (mostly Lagers) from the Vorarlberg region. Little Austrian craft beer but you can buy some BrewDog and Sierra Nevada here. Pretty useful supermarket.

A good Austrian (and some international) beer selection. You get the beers from local breweries as wel.

Large supermarket with a convenient location and ample parking. Decent selection of Austrian beers - only a few hard to get ones though. If you’re looking for general Austrian beers, it’s worth a stop. Fairly close to the German border around Lindau/Lake Constance.
