Garrison Brothers Texas Straight Bourbon Whiskey is bold, proud and authentic. It’s home-grown and handcrafted from the finest ingredients. Plump, organic yellow corn from the Texas Panhandle. Premium organic winter wheat that we grow ourselves here on the ranch and two-row barley from the Pacific Northwest and Canada. We grind our grain fresh daily and we cook our own sweet mash – one batch at a time. Then we marry the delicious distillate with fresh Hill Country rainwater that we harvest and purify ourselves.
