What's the recommended method for heating cold brew? I have recently started enjoying cold brew (over ice) in the afternoons. In the morning I still like my coffee hot. Is there a preferred or recommended method for heating? What factors should I take into account? I have tried adding hot water, but it makes the coffee too weak before I am able to get the temperature up where I want. Microwaving seems to negatively affect the taste.
The best result I got was warming up in a bain-marie. No science here---just my trials... I believe for now that bain-marie preserves more flavours and "respects" the aromas.



Heating cold-brew coffee was surprising to me the first time. Such unexplored flavours with the exact same beans I use for drip, etc. I hope you'll enjoy, and explore for more questions here!
