Might be that brother has gluten intolerance, or even worse, coeliac disease. My wife had to give up standard beer as a result of the latter - distilled stuff is ok as the gluten is effectively destroyed during processing. GF beer is available, but check that it is certified. Most is pretty horrible though :(
And it is all made from recycled dino poo anyway...
