I use to home brew. One time I made a wonderful tasting Double Diamond Ale recipe. My friend and girlfriend had dinner with us, I offered them my fresh brew and both loved it, she wasn’t even fond of beer. However, I had used a new, but very strong sanitizing agent to clean my lauter tun for this brew cycle. The next day when I asked him how he felt after drinking such a copious volume of vitamin rich ale, he said he felt amazingly good, all things considering. Then, I asked him if he had gas like I did; he told me he had an extraordinary volumes of gas, then I knew I had blown it, literally and figuratively. Never in my life have I ever felt like I was going to set the Guinness world record in gas production, in volume and duration, but I did then. Even though I thought I had it clean and rinsed, I still must have had agent residue remaining
Be careful with the cleaners.
