-Amber growlers are always best.
-Immediately rinse your growler when empty. You can rinse with a teaspoon of bleach for extra care. Don't use soap.
-Let air dry, and never ever store your growler with the cap on. It may look dry, but nasty stuff will still grow.
-Ask to have your growler sanitized prior to filling. Or you can sanitize prior to showing up.
