Just wait till you visit Texas. The parochialism is WAY over the top.
Shiner Bock sucks balls.
Houston-Nat's Texas Top Ten Beers
1. 512 Cascabel Cream Stout (Austin)
2. Rahr and Sons Bourbon Barrel Aged Winter Warmer (limited release) (Fort Worth)
3. Rahr and Sons Winter Warmer (Fort Worth)
4. Lakewood Lager (Garland)
5. 512 Pecan Porter (Austin)
6. Southern Star Buried Hatchet Stout (Conroe)
7. Live Oak Hefeweizen (Austin)
8. Peticolas Velvet Hammer (Dallas)
9. Rahr and Sons Ugly Pug Black Lager (Fort Worth) [EDIT: had the wrong beer here]
10. Lakewood Temptress Imperial Stout (Garland)
Only very limited releases are really worth having from St. Arnold's (Houston); I haven't yet sampled Jester King, Ranger Creek, or the brand-new Pedernales Brewery. Deep Ellum Brewery (Dallas) is run by hop-heads, so while I'm not especially fond, if you're a big hops fan their IPA is killer.
Of these, #4 is one of the tastiest lagers I've ever encountered, #2 ranks alongside Old Rasputin or Left Coast Voodoo Stout in my estimation, and #1 - 512 Cascabel Cream - is easily one of my five favorite beers.
