CraftBeerAtHome.com's founders Michael and Andy share a few things. They both love beer, particularly IPAs, and they both love to share their knowledge about beer with other enthusiasts. They decided to start an on-going, online class where they could chat with like-minded folks and introduce people to the process of home-brewing. They put together tutorials detailing how to brew different kinds of beers, how to cook with beer, and more general beer topics, such as favorite types.
