[I had in mind something modeled on Ninkasi's Total Domination, which without a doubt is the best beer brewed in Oregon and possibly the country. On this I am sure there will be no debate. And by the way has Ninkasi, in a short time, become the best Oregon brewery? I think it might. Kudos to Jamie Floyd.]
Anyway Steinbarts on Saturday was absolutely crammed with people buying supplies. Unfortunately I was after Centennial, Cascade and Chinook hops to make a classic 'Three C' IPA but the Chinooks were gone. Thoughts of substituting Willamette, Newport and Zeus were also dashed, so I decided to pitch a curveball: up the hops (to compensate for the lost alpha acids) and use Mt. Ranier instead. I'll let you know how it turns out. But the point is that this economic naturalist started to wonder whether, as incomes get strained, people start to make their won rather than buy it in the bottle. Does it make sense to do this in tight economic times?
Let's do some back-0f-the-envelope calculations. To get all the ingredients for my beer, plus a few sacks for the grain and hops but basically nothing else (including bottles and caps) I spent about $65. Blame the hops which are not only scarce but expensive. I had some leftover ingredients and I have all the other equipment from before so we will consider it a sunk cost and ignore it. So let's say $60 for the ingredients. From this I make a five gallon batch and I will probably yield about 4.5 gallons after ditching the sediment - maybe less because I dry-hopped - and then some spillage due to inevitable personal blundering, so let's say 4 gallons at the end or about 7 six-packs or 23 22oz bottles.
A six pack of good beer is about $7-$8 in my local supermarket. So the retail cost of this beer is about $50. If I manage something sublime perhaps I can compare to Total Domination which costs about $3.30 for a 22oz bottle, so my beer would retail for about $75.
On a broad scale then, the cost of the ingredients are about equivalent to the retail price of the finished product. Include the opportunity cost of my time, the certainty that my beer will fall far short of Ninkasi's and the extremely high probability that I will have managed to acquire an unwelcome bacteria that gives my beer an off flavor, and it seems clear that brewing your own is NOT a way to save money.
The crowd at Steinbarts could still be an indication of a bad economy: many people with unwanted time on their hands might turn to brewing which is a nice hobby and also has the appealing aspect of providing a large amount of alcohol at the end.
This calculation is, by the way, why I have largely stopped brewing: for about as much money as brewing my own I can get super-fantastic beer in many varieties and I don't have to wait for it.
