So I've at times had allergic reactions to beer and I couldn't find a thread here that addressed the topic (I did end up finding some after more extensive searching)...
Symptoms: Runny nose, coughing, lung congestion (like asthma)
So today I drank a St. Peters Winter Ale, Faxe Strong Beer (bear with me, I'm aging my brews so I'm trying not to consume them before they reach their prime). Anyways, I'm totally fine and then...I drink an Imperial Coffee Stout and can't even finish it my airway is full of mucus and I'm blowing my nose constantly.
Then I thought back, I've had the same reaction to Guinness and Fort Garry Dark.
So, I'm not allergic to yeast or gluten. Most beers and all breads are fine.
I'm not reacting to histamines from the fermentation process because I eat a lot of high histamine food with no reaction. What else is there?
The only connection I can see here is dark beer...what the heck could be in stouts and dark beer that would cause this reaction???
I figured who better to ask then home brewers to know/suggest/contemplate what ingredient might be setting it off.
