You are mistaken on all points. All EU states have a legal drinking age, and it is usually 18 or 16. Almost all countries, including Germany, also impose an excise duty (harm tax) on beverages like beer, but the amount of tax varies considerably by member state. It might be possible to order beer from some EU countries to others, but for example certain Nordic countries still maintain a state alcohol monopoly which practically makes it illegal for private consumers to buy alcohol online even from another EU country (more precisely, it makes the bureaucracy for selling alcohol so complex for the foreign retailer, that they just refuse delivery to these countries ..)
