It seems like once a year, I advocate for a shared taproom. Kind of like a food hall but with beer. Now comes news from Chicago about a 3-Way agreement that is new to their city.
One brewery, with two co-tenants. They each get 10 taps and can stay as big or as small as they need to, to make their economics work. I can think of a newly free space in DTLA that would be perfect for a situation like this (minus the self-pour, still not sold on that).
Call it an incubator or co-working space or contract but the point being that this can (if the breweries involved communicate well) be a great way to lower the entry cost and maximize the marketing. In big cities where rent is high it can really work. And if the barrier to leave is at a reasonable spot, it allows for new blood to be added on a rotating basis.
