The one in town near me usually doesn't have any alcohol at all, while the other few I've been at, had a fairly reasonable alcohol section.They are pretty similar across the board in Germany, there's a difference between northern and southern Germany but that's about it, and they just have a terrible beer selection. Aldi in general doesn't carry many known brands, most of what they sell are their own brands.
Usually wine though, I think.
Not much of an alcohol drinker, but it was weird how big of a difference there was between the stores.
