Signs your growler is gross
Since the onset of the novel coronavirus, the brewer will not only rinse a customer's growler, but they also sanitize it. “Growlers are usually dark glass,” says Lavery.
Do growlers need to be sanitized?
No matter what type of growler you have, you need to keep it clean. Many taprooms will clean the growler before filling it, but don't leave that to chance. Make sure you take a clean growler with you to get a fill-up.
Can I wash a growler in the dishwasher?
Leave the cap off until you bring it in to make sure it is as dry as possible. Putting the cap on traps any moisture and turns the growler into a petri dish. Also, running it through the dishwasher isn't really very helpful, because the mouth is so small.
