This seems like a late reply. I’m new here, so sorry about that. But I brew almost exclusively with TexMalt as my bulk grains. Sadly I don‘t believe you’re able to get directly through their website, but if you’re a Texan you may be able to find a homebrew supply shop that will sell you by the pound or in bulk if they carry.
With all that said, I enjoy them very much. Very good quality and I like to use and support local. I try to keep their Wildfire Pale and San Jacinto on hand.
