Hi everyone. Wooo, it's been a long time since I've been on this site. I used to do all-grain BIAB a few years back and had many thousands of dollars wrapped up in the setup. I loved it but, life happened and I ran out of time. Couldn't see myself ever having enough time to pull a full brew day anymore so I gave all my equipment to a buddy. Of course, the desire to homebrew never left.
A few weeks ago my boss tells me Pico is having a PicoC sale for $199/each. I'd heard about Pico before but kind of wrote it off. But, at that price, I couldn't really say no. So I dove in.
So far I've only done one batch and it's actually fermenting right now so I can't attest to the finished product. That actually starts out one of my biggest concerns about the thing: I don't understand how the airlock/fermentation is supposed to work and I can't find any good literature that explains it. I have hundreds of all-grain brews under my belt so I know how it's supposed to work but the little umbrella valves make me nervous. I think next brew I might just rig a standard airlock into it so I can watch it ferment.
Overall the appliance was very, very easy to use. I brew the "half-squeezed" IPA picopak and it was painless. Smelled great, temps looked good watching it on the log, and it was cool seeing it go through a stepped mash. Lots of hops and they smelled fresh-ish; grain seemed good too. Of course everything was sealed but not vacuum sealed so that means it had a chance to oxidize. We'll see when I finally get to taste it. I'm definitely ordering the "unpak'd" kit so I can take all my old recipes and modify.
I opened up the grain pak when it had cooled down so I could check the crush and the utilization. To my dismay, there was a section along of the walls that was dry. This is to be expected, of course, when you only have one inlet for water and no way to stir the mash. I also noticed that there were multiple crushes. Maybe each grain was a different crush or it was all standard 2-row crushed different ways; I don't know for sure but it obviously affected the flow and absorption. The dry grain had a good crush, same as what I would crush to when I was brewing BIAB, but the other grain/crush was way too fine and compacted and probably did not get a good sparge. Luckily it was towards the back and not along the bottom or I think it might have gotten stuck.
Pre- and post clean was super easy, but without being able to look inside I can't tell how effective it was. I used a distilled water and star-san solution for both rinses. I'm super paranoid about sanitization with brewing and as any old hat will tell you, DON'T FEAR THE FOAM, so when I buttoned up the fermenter and resevoir there was starsan foam and it caused no issues. I did read a review somewhere from a user that did a pre- and post-rinse after every brew, and did a deep clean and still got some debris out of it so I'll probably do a deepclean a bit more frequently than the every 3 uses they recommend. We wait too long for good beer and it's not worth waiting for spoiled beer!
Back to the fermenter, I just can't bring myself to ferment at the high temperatures they suggest for "fast fermentation." It goes against everything I know and I sure don't want a banana flavored IPA because I brewed at 77F. No thank you, I'll wait. Thankfully I still have my temperature controlled fermenter (aka deep freezer, natch) and I'll let it sit for 14 days and cold crash. But again, I really don't like not being able to see the activity and I'm just sitting here wondering if I have a stalled fermentation. Argh!
I think it's a good system, and I look forward to many more uses. Not having to bust out all the equipment and fire up the propane burner and clean clean clean is nice, as well as not having to monitor the mash. Oh, another thing I don't like is not having a counterflow chiller anymore. Taking a hot fermenter and just letting it sit until it cooled down takes away another step of something I used to have control over. I guess I just need to relax and trust the system. Maybe when i can finally take a sip of that first beer.
tl;dr- I like it.
