I wouldn't be able to celebrate the Great American Tavern without some 'tech talk' now and again, so I've put together the first of several how-to guides for our beloved barkeeps and proprietors.

Covers commercial taprooms, residential kegerators, and mobile draft beer systems. Download for $12 at the link below.
