Company email (March 2019) re: Coors Banquet
"MillerCoors does not use any animal by-products in our brewing process, nor are there any animal sources used in our packaging. Isinglass is not used in our brewing. There are five basic ingredients in all MillerCoors products. These include pure water, malted barley, corn syrup, hops, and yeast. Corn syrup is one of the basic ingredients used in most MillerCoors products as US consumers prefer its taste. Again, we do not use animal derived ingredients in our beer...

"The corn we use to make several of our beers may contain GMO due its prevalence in the U.S. corn supply chain, however, we regularly test our finished products and have never found detectable amounts of GMO in our beers."

Note from Thomas (December 2013): re: Redd's Apple Ale
"I searched the internet with no luck on if they were vegan friendly, luckly I located their customer service number 1-800-645-5376. The rep was down to earth, very nice and informative. The plus being they are vegan friendly!!!! Yayyy. I grabbed a 6 pack of each(yes I am impulsive that way) and let me tell you the flavors were like a candle-lit, romantic date in my mouth. Lol... I hope that you guys can do a follow up with the company to verify before I fall any deeper in lust."

Note: Miller does some kind of ad campaign promoting hunting, which may not be your cup of tea (though statistically drunk hunters seem to be best at shooting other hunters than animals, so...)
