As posted in other threads, I just started AG brewing with a full Ss Brewtech system. SS mash tun, HLT, kettle, and two unitanks. I thoroughly cleaned everything with TSP, rinsed, then ran Sani Clean through all the components. I have brewed three beers. The first I tried to burst carb. It had a metallic aftertaste, and odor in the foam. I backed that off to nearly no carbonation, but metallic aftertaste was still there. I still drank the flat beer though! After all, it was my first brew, and I was still proud that I made al-key-hal.
For water, I am just using tap run through two filters as I've been told that the Southern California (EMWD) water is "pretty good" for brewing. The two filter system has a copper pipe between the two filters, but that is the only non SS in my system.
I've heard that improperly stored grains can cause a metallic taste, but I've bought my grains from two different suppliers with the same results.
My second brew was an Irish Red Ale recipe from this forum. It had very good taste, but the metallic aftertaste was there.
Third brew was a honey blonde ale. This one is partially naturally carbonated. GREAT taste. My wife loves it, but it has the metallic odor from the head. Though it doesn't have the aftertaste. That's great, but I don't think I've had any commercially produced beer that had the odor in the head of the beer, and definitely no aftertaste.
I keep wondering if the water is the problem. Thinking about going with RO water and building it back up for the beer style.
I also wonder about the steel CO2 tank I'm using to slow carb. I've read in many places that the CO2 cannot transfer a metal taste into the beer, but that is still in the back of my mind.
Any suggestions on what I should look at? And yes...I am a perfectionist.
Thanks,
Fly
