These days, you can have beer any way you want it. With frizz, or without frizz, even regular to gluten free. Trying to figure out how much gluten is in a beer is a bit complex. Since beers are made from grains, many people assume that having an allergic reaction to grains will automatically make them allergic to beer, too.
This is not always the case, though, especially with the technology and innovations we now have, enabling beer companies to cater and produce for all types of market, even producing beer for the gluten intolerant peeps.
