I've been reading about making cold brew coffee and would love your input. I myself am not a cold coffee drinker, my husband is and I got him a cold brew coffee maker (just a jar with a filter basically) for father's day. I'm just getting around to using it today and I thought I'd ask around about it. I'm reading that I can just leave the coffee to brew at room temperature overnight. It's pretty warm here in the summer time and we turn off the AC at night except for the bedroom. Is it ok to cold brew in a warm 85degree room or will the job be done just as well in the refrigerator? Will the refrigeration affect the cold brew process? I've also read that cold brewing doesn't necessarily mean cold coffee. Some people brew their coffee cold over night and then warm it up to drink it. Supposedly this cuts down on the acidity of the coffee which would be very helpful to me as I suffer with with acid reflux and my doc lectures me to eliminate my treasured single cup of coffee that I drink in the morning. Also, how long does cold brew coffee last in the fridge? Any safety factors involved?
