Preaching a trifecta of integrity, solidarity, and craftsmanship, this craft brewery is a must-visit. Founded in commemoration of Abraham and John Erb, two Waterloo Mennonites of the 19th century, Abe Erb serves up an excellent of house-brewed craft beers, imaginative cocktails, and delectable food. Every batch is custom and can only be accessed via its in-house beer shop or its restaurant portion of course.
