I have been DIY juices for a couple weeks now. I like to use the hot water bath to help decrease steeping time. I had the idea to put bottles of fresh mixed juice on the defroster vent of my truck. I commute about an hour each day. In the morning I line up my bottles on the dash and put the defroster on hot and low and let that warm up my juice. Each stop light I give them a shake. By the time I get to work the color has darkened dramatically!! If I wanted to, I could easily steep a dozen bottles at once with this method. Might look weird shaking bottles at stop lights, but it's easy and works well!
