I heard someone mention on here an aquarium pump, but I couldn't find it. So... I had an old aquarium air pump. I found a little box about the size of a stick of butter, and used double sided tape to stick it to the top of the pump. Now I have a tray that I can set 3 bottles of my mix into. I mixed up 2 bottles last week and heat steeped them for about a half hour, and then put 'em into the tray and turned on the pump. 6 days of subtle but intense vibration later, it tastes nice and mixed! I think it will get even better with more time, but I'm happy as hell. (btw this is a coffee caramel mix about 70/30)
