Careful Cellaring, Part 4: The Barrel Maintenance Program for Living Beer

We couldn't have a blog series on the intricacies of beer cellaring without addressing the challenges and benefits of having barrel program like ours at The Bruery. In order to produce beer that is up to our quality standards, our wood cellarmen must take utmost care in working with our barrels and beer. To further explain how our barrels are taken care of, our team of wood cellarmen, Cesar Alfaro and Brett Richman, explain the basics and some FAQs.



Here at The Bruery it's the wood cellarmen's duty is to make sure that the beer that comes out of barrels are of best quality and, of course, taste delicious. In order to do so we take a lot of measures to make sure the barrels are in perfect condition before beer goes into them.

Careful Cellaring, Part 3: The Threat of Light

Another factor that can be damaging to you beer cellar is light. Did you know a beer's flavor can change in minutes in direct sunlight? Even unnatural, fluorescent light can harm your beer. The reason this happens is because the hops in beer are very sensitive to UV light. To explain what happens to the chemistry of beer, we turn again to Jess from our lab. 

Ever wonder why "lite" beers in clear bottles taste better with a lime slice and are skunky without one? It's because of a little nasty compound called MBT or as the organic chemist might say 3-methylbut-2-ene-1-thiol.

The odor and flavor of this compound is often reminiscent of skunks but is commonly referred to as the smell and taste of a "lightstruck" beer. The chemistry that goes on to change your delicious hops to skunkiness is well known and shown in the following graph about "The Lightstruck Reaction" (Graham, 2006):

Careful Cellaring, Part 2: The Importance of Temperature

Cellaring beer properly means paying close attention to the many elements that can make your collection age for the worse. One of the most influential factors that can cause any good beer to go bad is temperature. To best understand how temperature effects beer we've once again turned to Jess, our Quality Specialist, to explain what happens to a living beer when it spends time at less than ideal temperatures.

Why do you keep your milk or yogurt in the fridge? For some of the same reasons you would want to keep a beer in the fridge: it helps keep the beer as fresh as possible.

Too Darn Cold

Cold storage is not to be confused with frozen storage. Besides possibly making a beer-bomb in your freezer, keeping beer at sub-zero temperatures is not preferable. There actually are a few instances where freezing temperatures are used in the brewery:

Careful Cellaring, Part 1: The Quality Assurance Process for Creating Clean, Living Beer

Before a beer leaves our brewery to go to your cellar, or your bottle share, or your mouth, it has a very busy schedule as it gets approved for its release into the world. We've explained previously how working with sours comes with its own trials and tribulations, but for cellared & aged beer month at The Bruery we think it's time to delve deeper into the steps it takes to produce and release clean, cellarable, living beer.

As many a craft beer lover may know, the brewing process requires a ton of cleaning and serious attention to sanitation. This attention to detail doesn't just apply to a single brew day. To make sure a beer can be sold and consumed as it was intended to taste, every part of every brew endures our quality assurance process. It takes all levels of staff to pull this off, including our brewers, lab ladies, packaging, cellarmen, and managers. We love to make experimental ales, but with each unique experiment comes new challenges for our team to monitor.
