True. It also matters what you're doing with it. Are you adding cream and sugar. I like a cold brew and tonic and to get the cold brew to stand up to the tonic I brew between 24 and 36 hours. If I'm sipping on it as is I usually only let it go overnight.

I'll also do batches where I brew it with only enough hot water to let the coffee bloom, then drop ice water on it and let it sit overnight. That's been my favorite so far.
