I have been very into making cold brewed coffee
lately. I find it is the best tasting coffee I have ever had. The acidity level is so low that it is just that much more enjoyable to have a cup or two.
For those that don't feel like reading the link above, the basic idea is that you combine coffee grounds and room temp or cold water and let sit for 12-24 hours and then strain. Depending on what coffee to water ratio you use you will end up with regular coffee or coffee concentrate. I have been making coffee concentrate. I combine a bit of concentrate with hot water for a hot cup or concentrate with cold water for iced coffee.
Right now I have been keeping the concentrate in the fridge. I take my coffee black, but my with uses milk. I like my coffee as hot as I can get it. She does not mind hers a bit cooler, but both of us have found this method leaves our cups a little cooler than we would prefer.
My question is would it be safe to store the coffee concentrate on the counter instead of the fridge. I am guessing this would not be OK or at the very least it would cut how long it will safely last from 2 weeks in the fridge to much less on the counter. Any thoughts?
