German here who was 13 in the 90s - while I'd heard of several people (and friends of mine) who drank alcohol at 13, it was a lot more common at 15 (but mind you, we're allowed to legally drink beer with 16, so I don't consider drinking beer at 15 a big deal). All mostly middle class children who went on to go to uni, maybe the occasional outlier with a less than normal home situation. They did want to see government IDs in shops, but I guess that highly depends on the shop or your exact location.
