Hmmm, I didn't express myself well, did I? Lagering was a means
to being able to consume beer in the warm summer months, not
produce it in that season. It required brewing a full year's
worth of beer in the cold winter and finding some cache that
stayed cold during the summer, like caves in the hills.

San Francisco never gets down to the necessary lagering temps
due to the strong moderating effect of the ocean. Before
widespread mechanical refrigeration (a product from the 1880s,
well after Steam beer was created for the benefit of the
'49ers), there was no way to make a lager beer in SF, regardless
of season. Any attempt to do so would produce a more estery
beer that fermented explosively.
