A friend of mine and fellow Ag has launched a brewery in Wolfforth. Check them out at http://wickedbeaverbrewing.com/. They are available at Crush and Cattle Call in Amarillo and The Lantern Bar and Fox&Hound in Lubbock.
Fox & Hound apparently flaked out. Beer is available in Lubbock at The Lantern on tap and in bottles. Bottles can be purchased at Ollie's on 34th and at Host & Toast at 26th and Boston.
Unfortunately not. Texas laws keep production breweries from selling product directly to the buyer. I believe they are in a few stores in Amarillo and I know they have bottles at Host and Toast right by J&B coffee in Lubbock. They also have a tap at the Lantern in Lubbock.
Dublin is correct. State law prohibits purchasing directly from the brewer. But for you out-of-town visitors, they are now on tap at the Overton Hotel.
