I've just finished doing 6 months of ABVD chemotherapy treatment to slay my Hodgekin's Lymphoma. Obviously now, I look at what's in my vittles and swig a bit differently. A few chemicals I brewed with in the past are making me scratch my head. Not necessarily in a bad way, more or less a questioning one. I'd like to try and "return to the land" in some sense. Eliminate the synthetic from my diet in a nonjudgmental, hippy way
Like Campden tablets
..I know they're toxic in concentrated samples, but does the potassium metabisulfate break down enough not to affect us? Or is the composition broken down with aging? Or the Potassium Sorbate that follows?
Or even a cleaning agent like Star-san. Has phosphoric acid been shown to be nasty stuff at all?
Guess I'm trying to ask, could you list what "questionable" additives that we use in our beer, and why it seems a little sketchy to you? What I mean by questionable is basically, unnatural.
Oh and FWIW, I'm a firm believer that homebrew contributed to my overall getting better. We're talking homeobrewpathic, and metabrewphysical statures of life. It provided me with something to do around the house when I was down, and was a beautiful escape and tonic when needed most.
And I'm well aware that homebrew is almost completely additive free, it just seems that a few chemicals fall through the cracks in certain situations.
HBT-WHAT'S BAD IN OUR BEER?
