Why Worth? Because it's brewpub is 20 minutes from my door. It bills itself as the smallest commercial brewery in the nation. Peter Ausenhus, who learned his trade working at Summit Brewing, brews 10 gallon batches. Lots and lots of batches of obscure beer varieties. Why am I posting this now? Because Iowa has overturned an old law which restricted Iowa brewed beers to be 5% alcohol or less. The rules have changed.
