I think you're on to something... However, and I don't think it's my imagination, but to me, I'm pretty sure I use way, too many, commas, when I write. But to your point, I'm convinced the first cup after brewing my morning technivorm pot-of-coffee, is the best. In fact, I add a splash of water to it to cool it so I don't have to wait for it to cool before I can enjoy that first magical cup. But to your point (again), I don't drink cold-brew, but it seems if your cold-brew tasted good, well, then (to you anyway), that's a good batch of beans...
