Do they usually have cans or only during certain releases?

They do have cans on non-release beers.

Can available Tuesday to Saturday (releases). Depending on the release they can run out somewhat early (say between 2 and 3) or sometimes stuff last until the next day. Hard to say. Follow on IG for more real time updates and check the website for the release schedule (Double IPAs go faster with Swish going in the 3 hour time frame with long lines for sure).
