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

47 min16 februari 2025

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.
