I'm also fond of beer, but I have a solution. I buy pretty good beer for myself, and the cheapest, vilest brew for the slugs. THAT, I don't mind sharing.
And maybe, when I work off that nasty stuff in little slug swimming pools, I'll make a batch of Slug Beer:
2 cups warm water,
1 pkg. dry yeast,
1 teaspoon sugar,
1 teaspoon salt (or less)
