I love cold coffee and have been shopping for a cold brew system when I came across Bizzy where all I needed to do is place two fantastically smelling pouches in a pitcher of water over night and in the morning remove the pouches adding three more cups of water. I thought there is no way especially how other sites have these elaborate systems, but the coffee tasted great. I actually use less creamer so I can taste the coffee more with no bitterness. I am sold and will be a Bizzy member at least until I retire. I just hope more flavors are to come. My whole team at work now knows about Bizzy and the ease to making this coffee--It has me less cranky in the morning. I know you said to leave out in room temp overnight but it has tasted the same in room temp or the refrigerator.
