If you have ever read a home espresso forum or hung out long enough with coffee geeks, inevitably the terms "grind retention" will arise. It is a fascinating subject - that combines a bit of engineering, physics, and economics. It affects all coffee grinders and when it comes to espresso it can be the difference between a perfect shot of espresso and... well, a mess. As we have not touched on it before, we produced a video to run through:
- What is grind retention?
- Does it matter?
- What do you do about it?
- Which grinders are best at each price point?
Regardless of your budget, brew method, or whether you intend to single dose or not, we recommend giving it a watch so that you can pick an espresso grinder that suits your ideal home espresso setup.
