I assume you are standard fermenting? What temp
All 3 batches so far have been at ambient temp. I'm in Los Angeles, so in my house that's...tough to say
My house is over 100 years old and has absolutely no climate control. No AC or heat. We dont really have 'weather' so as long as you're not brewing it's not a huge deal.
First batch fermented way too hot because we had an unseasonably hot spell in October. Batch tasted like crap, ended up dumping half of it. I dont like stouts all that much and it was my 1st try so I didnt cry over it.
2nd batch tasted very sour and medicinal. Pretty sure I dry hopped this one too long. Drank the whole batch. Seemed to be slightly better when I spooned the head off of it.
3rd batch fermented too cool (I guess). Used a brand new keg for this batch. Cleaned and sanitized of course.
The only things in common for all 3 batches were the Pico unit itself, and the keg lids. Since the last batch, I've run 2 deep clean cycles. The keg lids just have a...stink to them. Even after multiple washings. All 3 batches have had this same sour stink. Emailed Pico support and they blame my soaking them in PBW. Whatever.
This is why I havent left any reviews for the pico paks. Theres just waaaaaay too many variables outside the control of the brewery putting their name on it. At this point, I'm a bit surprised that the average person could produce a good beer using following only the instructions they provide.
Pretty much any beer that comes out tasting like crap is the fault of the end user, I know this and accept it. I'm just trying to figure out where in the process I'm causing the problem. I'm finally able to control my fermentation temps, so hopefully that's all it was. Back to the drawing board with fingers crossed.
