Rites of Passage

I was doing some cleanup after our last batch and noticed that one of my Better Bottles had some cracks in the bottom rim. It's not the first piece of equipment I've had to retire. I had another Better Bottle which I've designated for Brett fermentation only, an autosiphon which has visible scrapes and scratches all over the inside of it which I pitched, a few beakers which were process casualties and at least a couple of stir bars which made their way down the drain. And not to mention Jeremy and I have started following Jamil's recommendation and replacing all of our soft plastic tubing every year.

All in all, equipment casualties do seem to be par for the course in order to maintain proper sanitation. Given space to "cellar"beer (at least to the best that my basement can maintain cool temperatures during these Chicago summers) we've seen infection crop up in beers after they sit for a while. I know that there's some wild yeast and bugs floating around in my back yard and basement, but changing out equipment seems to have bought us more stable beer for now.

It's not just equipment that starts to fall by the wayside as you get better. Once we hit the point where our beer started to consistently taste really good, it stopped making sense to stretch ingredients. Old hops which had sat warm or grain which had not been properly stored got pitched, as do anything which doesn't taste or smell right before a brew day. Ultimately it's a little less economical on the front side, but I'd rather spend a few extra bucks on equipment and ingredients than end up dumping a whole batch because of contamination. And I'm pretty sure we're all in this hobby to make good beer, right? 

Public Service Announcement

(Lifted from Goose's Website.)

Go buy yourself a four pack of Goose Island's Matilda. And don't drink it. Seriously - do yourself a favor and sit on it for at least year.

I live in Chicago and drink a handful of Goose's beers on a semi-regular basis. I've always thought Matilda was a good offering, but never something I'd seek out. Fresh from the brewery it's a bit too sweet and my take was always that Goose was doing a crappy job of trying to produce a Belgian Golden Strong or a Tripel.

I was dead wrong. I hereby apologize to Goose Island for unfairly discrediting them on this effort. Until I really upped the ante on my knowledge of beer styles (through the BJCP and my own brewing) I was sadly unaware of the existence of 'Belgian Specialty Ale', a category created specifically to capture Orval.

As such, I just didn't get this beer. But last summer I got a few four packs and just let it sit in my basement, waiting to offload it onto some family or friends during a special occasion or a gathering at my house. During that year of aging, something magical happened. The brett introduced during barrel aging woke up and went to work. The beer dries out and gains an entirely different dimension of complexity. T distinct barnyard funk and some of the other more distinctive esters from brett become more pronounced and round the beer out.

So maybe it was just my ignorance of this style, the less evolved and less funk-friendly state of my palate, or maybe it was just the fact that I've never had the chance to try a substantially aged sample of this beer. But I was missing out. And if you've never had Matilda after some cellaring, so are you.

Brettanomyces

I brewed a dark cherry lambic back in June and it's been aging in a carboy since. I'd only made one prior attempt at a lambic much earlier on in my brewing career, which I ended up dumping. Thankfully I've learned enough about yeast, bugs, and sanitation that I understand what I did wrong the first time around. This batch looks and smells like it's supposed to, although I haven't tasted it yet to be sure how it's coming along. I thought everything was good. I was wrong.

It seems like I either have brett lurking somewhere in my equipment or I have a natural source of wild yeast in my back yard or basement. Since then, I've had one batch I tossed because of contamination and traces of it show up elsewhere.

The first hint that something was up was a ten gallon batch of Firestone Double Barrel Ale clone which was split into two fermentors and pitched with two different yeasts. One of the batches turned out amazing, and the other was infected. The process for both was literally identical up to the point of pitching. The results couldn't have been more dissimilar. The aroma, taste, and even then color of the two beers was distinctly different.

So after a bit of research, I tossed all of my old plastic tubing, and brewed a batch of my ginger wheat which I fermented in a V-Vessel. (Separate post on that at some point.) I racked a gallon off into the sanitized, but possibly contaminated better bottle and let it sit for a couple of weeks. The test was inconclusive, and in hindsight I probably should've bottled up the results and done a "forced" conditioning at high temperatures to see if there really was anything at work.

But in any case, here are the steps I took / have taken since.

I bought a new better bottle and hardware for it.
I replaced all of my tubing and hoses used on the cold side of the process.
Instead of using a brush and mild detergent, I upgraded to PBW for cleaning the Better Bottle.
My keg cleaning regimen now involves a soak in PBW, scrubbing, a rinse and then a soak in star san instead of just a water rinse / scrub and a sanitizing cycle.
I've started buying fresh, clean bottles for anything which is going to need to age and only using recycled bottles for short term transportation.
As much as my limited space permits, I keep all of my aging beer cold.

After all that, I can't definitively say that I've beaten or contained that troublesome but wonderful bacteria lurking in my brewery somewhere, but I do brew with more confidence that I won't have to pitch any more batches soon.

Anything I missed?
