Holds 45 bottles. This is how to make bottling simple. Rinse the bottles out well after use and store upside down on the bottle tree where they remain clean. When you want to bottle, utilize product B520 (seen below) to inject sanitizing solution, such as Star San or SaniClean, into the bottles to sanitize. Wait 1 minute and bottle. You can also do the sanitizing ahead of time and let the bottles air dry upside down.
