Fruit juice or creamy almonds? Your guide to controlling cold brew flavors

When I started making cold brew this last year, I treated it like hot brew filter coffee. But no matter how I adjusted the grind or tweaked the brew time, I hardly got any differences in flavor… Then it hit me: cold brew isn’t just a slower hot brew—it’s a completely different game with its own rules! In this episode, I speak with leading coffee researchers who break down the microscopic dance between water and coffee that explains why cold brew plays by its own playbook. And I bring you in on the brewing secret that can turn your brews from fruit juice to nutty creaminess. --------------- Please spread the word about The Science of Coffee!
