So, I was trying to find some information on the additives that they put in beer, and I didn't really find much. I found this page http://foodbabe.com/2013/07/17/the-shocking-ingredients-in-beer/ which claims there's some book “Chemicals Additives in Beer” by the Center of Science and Public Interest.
Anyway, they claim that these are some of things that are added into beer
Monosodium Glutamate (MSG) – alcohol is already addictive with some people, but with MSG?! Holy smokes.
Propylene Glycol (an ingredient found in anti-freeze)
Calcium Disodium EDTA (made from formaldehyde, sodium cayanide, and Ethylenediamine)
Many different types of sulfites and anti-microbial preservatives (linked to allergies and asthma)
Natural Flavors (can come from anything natural including a beavers anal gland)
High Fructose Corn Syrup
GMO Sugars – Dextrose, Corn Syrup
Caramel Coloring (Class III or IV made from ammonia and classified as a carcinogen)
FD&C Blue 1 (Made from petroleum, linked to allergies, asthma and hyperactivity)
FD&C Red 40 (Made from petroleum, linked to allergies, asthma and hyperactivity) FD&C Yellow 5 (Made from petroleum, linked to allergies, asthma and hyperactivity)
Insect-Based Dyes: carmine derived from cochineal insects to color their beer.
Animal Based Clarifiers: Findings include isinglass (dried fish bladder), gelatin (from skin, connective tissue, and bones), and casein (found in milk)
Foam Control: Used for head retention; (glyceryl monostearate and pepsin are both potentially derived from animals)
BPA (Bisphenol A is a component in many can liners and it may leach into the beer. BPA can mimic the female hormone estrogen and may affect sperm count, and other organ functions.)
Carrageenan (linked to inflammation in digestive system, IBS and considered a carcinogen in some circumstances)
Like I said, this could be true, it could not be true, but how are you supposed to know if we have no idea what they actually put in what beers? It seems awfully suspicious that they refuse to tell anyone what they put in their beers.
