There probably isn't an EU-level limit, but member countries can set them. In Finland you can bring as much as you want for your own use, but past some point you need to be able to actually prove that it's for your own use. Current guidelines are: 110 liters of beer, 10 liters of other alcohol drinks, 20 liters of max 22 % intermediate products, 90 liters of wines or fermented long drinks/ciders. Common reasons for bringing more than that are e.g. your own wedding.
