Homebrewing is hardly a stressful endeavor. The busy moments that demand immediate attention are divided by plenty of relaxing interludes. That’s why brew day is a great time for friends to drop by and share a beer while the next batch is underway. Lending the occasional hand is natural; sometimes I’ll draft someone to help haul the spent grain to the compost bin or I’ll watch over a boil while my friend steps into his house for a moment. But actually partnering with another brewer can be quite beneficial. Part of the appeal is that brewing a 10 or 15 gallon (38 or 57 l) batch is about as easy as 5 gallons (19 l), as long as your equipment has the capacity. Sure, you could do that on your own, but then you’d end up with less variety in your kegerator as you work your way through the larger volume of beer. On the other hand, splitting everything with a friend—the cost, the labor, and the beer—can be a win-win situation. Aside from sharing the load, you can get a creative boost from the joint effort.
There’s a synergy in working together, where each person brings his or her own experiences and interests to the party. Think back to when you first started brewing: every batch was a fresh opportunity to learn the craft. After a while, though, you may have found yourself following the same short list of recipes because they’re dependable. Collaborative brewing gives you another set to draw on and spurs you to pick up new styles and techniques. Even seeing how another brewer handles familiar processes can offer enlightenment or suggest shortcuts.
Aside from pooling your collective knowledge, a brewing partnership encourages experimentation. Dividing a 10-gallon (38 l) batch of the same base beer is a great way to compare different yeast strains, fermentation temperatures, or even cask conditioning vs. bottling. If you’re willing to take on some extra work, a shared mash can be split into separate boils to support playing with different hops varieties or hopping schedules.
