Can someone please list all achievements you can get during Alegarten please? I still have not found all of them.

I don't believe there are any Alegarten specific achievements besides the Drunk Gunter ones. Give x amount of beer items to drunk Gunter.

You can also get the items for a couple collection achievements from the Brewery: "Alegarten Books", "Prepare for Alegarten", "DRINK DRINK DRINK", "Pretzels", "Six Pack", "The Wurst", and "Velvet".

Thanks!

What do I have to do to get the Velvet achievement?

I heard that by feeding a Honey Sweetened Milk to your pet you can get another achievement. I did feed it to one of my pets but nothing happened ):

Feed your pet all of the velvet whiskey bags. The Honey-Sweetened Milk is part of an achievement as well, but it's not the only thing required and only one other item for that one is sold at the Brewery.

Do you know which items I have to feed to my pet to get that achievement? :3

Not offhand. Just go to the achievements page and search "honey" and it'll show up.

thanks again (:
