I picked up these [ornament storage containers](Sterilite 20 Compartment Adjustable Christmas Holiday Ornament Storage Box, Red https://www.amazon.com/dp/B01N455YDY/ref=cm_sw_r_cp_api_YLpsAbJPJRSJ6) for like ten bucks each at walmart a few days ago. They are perfect for concentrates and mixes. The slots are modular, so I've got mixes grouped by type and date, same for concentrates.
