I have a feeling the first round of Ames Lager is going to sellout FAST.
I think you are right and I think it will be interesting to see how West O reacts to demand. I would guess initial demand (new thing + fall football season) will start really high. But probably naturally level off a bit lower eventually. It will likely be hard to keep up for a while which will also help sustain demand (when you can't get something it always helps). But they also can't over invest in equipment/inventory if things fall off from the initial peak.
Based on West O's output shown in that article I'd guess they are in the neighborhood of a 15BBL system which is roughly 450 gallons or roughly 5000 12 oz cans. Assuming they are brewing 4 times a week total but they are still going to be putting out other beers even if Ames Lager is the priority. So say 10,000 cans a week of Ames Lager. (that's super rough math with little thought so forgive me if I'm off)
I really don't have a feel for how demand will settle out long term, but during this first fall football season I don't know if that will be enough to keep up.
They could double that capacity pretty easily but there is lead time to that as well. Lagers also take longer to finish. We aren't far from the day the beers we drink at the UNI game will need to be in the tank. I'm sure they have been brewing like crazy the past couple months to get ahead of things, but will be interesting to watch.
I don't think any of that is bad, in fact being a bit hard to get might be good. Just a warning though that it's very possible you'll see more Swarm on shelves this first fall than Ames.
West O is a solid brewery as long as Ames Lager is good and they can maintain their quality as they scale up (lots of breweries struggle with that) I really think this will jump them up into that pack of brewers in the 5000 BBL/year range in the article above.
(sorry my beer nerdiness took over there for a bit)
