Do you want to reuse your growlers? This at-home method has worked well for cleaning and storing growlers with no lingering odor or growth inside the bottles.
The first step is clean the growler immediately, or as soon as possible after consumption. If you can’t clean it quickly, keep it refrigerated until you can. That way you won’t get any funky growth or dried residue that is a pain to remove.
- Heat oven to 225 F
- Boil a small pot of water
- Remove cap, if Grolsch style, pull off the bottle
- Put a couple drops of dawn dish soap in the growler and rinse with hot tap water and then cold so there are no suds remaining
- Pour a small amount of Star-San solution into the bottle and swirl around enough to have solution coat the inside of the bottle, pour excess out (or into the next bottle)
- Turn off heat on pot, put the cap in the boiling water for 2-5 min and remove
- Put the bottle in the oven for 10 min, remove and shake to disperse any remaining Star-San solution
- Put back in the oven and turn off
- Remove bottle after 20 min and allow to cool
- Put saran wrap over the bottle top and put the cap on, the bottle will remain perfect until next use
Star-San solution – 7.5 ml solution to 32oz water, a spray bottle works great
