There are many things that can go awry during the brewing process. Anything that happens before your wort hits the fermenter is fixable, for the most part. Unfortunately, there’s not a lot to be done to salvage your precious beer if you encounter issues during fermentation. There are, however, a few steps you can try along with tips to avoid future tragedy.
The most important step that should be taken before any kind of fermentation begins is cleaning. Everything that touches your wort post-boil, during fermentation and post-fermentation should be sanitized. Use a cleaning solution that won’t leave a residue but will adequately remove all debris from equipment. A variety of chemicals are available at your local homebrew shop. What works best for you might not be what someone else prefers. The same goes for sanitizer. Ask your homebrew shop attendant for advice. That being said, this isn’t the Dark Ages and there are much better reasonably-priced options on the market besides bleach. The cleaning agent and sanitizing solution should always be two separate chemicals. While most cleaning agents can also act as a sanitizer, it’s best to be overly cautions.
The next thing to address is the fermentation equipment. Whether you are using plastic buckets, glass carboys or stainless steel containers, be sure that all the parts and pieces fit well to create tight seals. The stopper the airlocks go in need to be the right size and make sure that there’s only one way for gas to leave the fermenter. This will allow you to see active fermentation and it reduces the chance that something will find its way into the batch. Remember, the airlock is the line of defense against the outside world.
Sometimes liquid in the airlock can get sucked into the fermenter. And if there is anything undesirable in that liquid — a dead bug, for instance — you might infect your batch with bacteria. To avoid this, use sanitizer or 100-proof alcohol on the airlock just in case anything does reach that device.
Now that the post-boil equipment is cleaned, sanitized and properly installed, the next step to ensuring proper fermentation is the yeast itself. Proper pitch rates and ensuring there is plenty of oxygen are just a few factors to consider. When building a recipe, be sure you have a high starting gravity and account for that with a little more yeast than normal. That way your fermentation won’t stall, which could result in a product that is under-attenuated and too sweet.
Yeast doesn’t like to be abused, and the easiest way to hurt your yeast is with large temperature swings. If you are using a liquid yeast, you want it to be as close in temperature as the wort you’re pitching it into. A large temperature gap can rupture the cell walls of the yeast. Don’t let the yeast get too warm, though. If fermentation is too hot, you could end up with an entirely different set of problems.
Yeast also have two stages of fermentation. The first is aerobic where they actually consume oxygen to multiply. The second is anaerobic when the yeast begin to consume sugar and create all of those wonderful byproducts. The best time to introduce oxygen to the wort is before the yeast is pitched and after the wort is cold. Introducing oxygen after the pitch might create off-flavors.
As homebrewers, we can only guide the yeast to help us create award-winning beer. Give those little guys a fighting chance to reduce chances things will go wrong.

From a free bike share program to special brews for community causes, Eugene brewpub Falling Sky is always involved.
“We’re really receptive to any partnership with the community, especially if it’s something that we align interests with,” says co-founder Jason Carriere. “We’re very open and connected to the community. We don’t turn people away.”
Falling Sky supports many causes that are rooted in sustainability and environmentalism. It’s part of what Carriere sees as the cyclical nature of brewing, which is a business that depends on healthy natural resources and agricultural products. “We depend on the ecosystem to provide what we need to make good beer.”
Falling Sky’s commitment to the environment is visible as soon as you walk up to their Pour House & Delicatessen at West Eighth Avenue and Blair Boulevard. Seven bikes are available free of charge (with a $150 deposit on a credit card) for anyone to borrow for up to 24 hours. Falling Sky supplies locks and helmets, and the bikes have built-in lights. Local shop Arriving By Bike keeps the cycles in good repair.
“We have a lot of people who come to Eugene from out of town,” says Carriere. “This has been a good way for them to get around town without too much trouble.” Sometimes people just ride along the nearby riverside bike paths or use the bikes to check out different neighborhoods while looking for housing.
Other Falling Sky programs tend to focus on special days where portions of certain beer sales go to a particular cause. Sometimes Falling Sky also works with nonprofits or other organizations to brew a beer around a specific cause. From initial conversation to rollout, it usually takes four to five weeks to develop a promotion. However, it might take up to two months if there is a beer release involved. “We typically just get together and have a meeting, talking about what they’re interested in,” explains Carriere. “We try to pick (a beer style) that appeals to a broad base of people, so that we can really pump up the beer and the connection with the charity.”
Recent examples have included Tree Line Pale Ale, brewed in support of Friends of Trees, a Northwest nonprofit that plants and cares for urban trees. Falling Sky donated $1 for each Tree Line pint sold, as well as $5 (enough to buy a tree) from sales of a special Friends of Trees T-shirt. In a similar vein, $1 of each pint of Floodplain ESB went to support the McKenzie River Trust, which helps protect area watersheds and critical habitat lands.
After winning an award for best medium-sized transit district in the U.S., Lane Transit District (LTD) reached out to Falling Sky. They collaborated to brew Mash Transit Ale, an English-style pale ale, to publicize and celebrate LTD’s achievement. Purchasing a pint came with a bonus: a free bus ride. Falling Sky also donated $1 of each pint of Mash Transit to Lane Coalition for Healthy Active Youth.
“We consider mass transit an environmental cause, in terms of keeping cars off the roadway,” explains Carriere. “It encouraged people to ride the bus who don’t often ride the bus.”
Falling Sky community support efforts can also be as simple as a flyer and a one-day deal. By bringing in an organization’s printed flyer or graphic on a smartphone or tablet, a customer can have 25 percent of their purchase donated to the cause.
For larger promotions and support, Falling Sky leverages in-house resources for brewing a special beer, promoting the cause in its locations and across social media, and developing a custom T-shirt. “We’ll do a beer release event where they can come in, set up a table, share information and talk with people,” explains Carriere. “It gives them a platform to get their message out. And when we go out to sell the beer, we also try to bring out promotional materials for the cause too.”
Coming up, Falling Sky is brewing a kolsch to support The Oregon Brewshed® Alliance. It will be released during the week of Earth Day (April 17–23).
“We’re a really small brewery,” says Carriere. “We don’t have a community outreach director or anything like that that some of the larger places have, so we rely on the community to come to us and work with people. Typically (co-founder) Rob Cohen, lead brewer Scott and I sit down with you and figure out what we can do to help.”
