Since I'm just starting out with equipment from my all- in-one box starter kit...I am hesitate to purchasing a number of different sizes of carboys. My problem is storaging the carboys. I just downsized to a very comfortable small home. I've been looking at options that might help me maintain a reasonable amount of carboys . Noticed one option was to use Glass Beads to top up. Has anyone used this method or have a better idea. So far I have 1-6 gallon plastic carboy, 2- glass 5 gallon carboys , and 1-3 gallon carboy. Thanks.
