We're all tired of buying growlers because we forgot ours at home. Enter the Crowler—a 32-ounce tallerboy of tap-to-can goodness that is quickly taking the craft-beer world by storm. Developed by the Oskar Blues Brewery in Colorado, the on-demand cans are quick, cheap and a great way to savor something rare in its most brewery-fresh state. With the Crowler well-suited for beaches and bike trails where glass is a pain, a growing number of Portland bars and breweries are putting them on offer.

Here are some spots that carry the new can-do.
