For my third installment of Adventures in Cold Brewing I offer a quick note on repetition. For this experiment I started with my usual Mason jar cold brewing routine. After my standard 12 hours I filtered the coffee, reset the mason jar with fresh coffee grinds, and poured the coffee back in instead of fresh water. I repeated this process every 12 hours for 3 days.
To prepare a cup I boiled some water and diluted the concentrate about 4:1. This was probably the best coffee I’ve made yet. I’m not sure it was worth the time and trouble, but it was very good. Once I figure out how to improve my filtering process so it’s not so time consuming I think I’ll try this again.
