I’m going to throw you a curve ball and suggest just using the French press to make cold brew coffee. It’s hard to explain the flavor difference between a hot cup of coffee that has gone cold and a cold brew cup that just is that temperature. To me it tastes fresher somehow, more subtle flavors emerge, and it tend to be smoother. I don’t always have time to leisurely drink a cup of hot coffee in the morning. I hate drinking hot beverages when on the go. I’m not a fan of hot coffee that’s gone cold either. Cold brew solved each of those issues for me. Your wife might also appreciate that it doesn’t smell strongly either.
