I've been trying to find the best grind size to use in my Bruer cold drip setup. I bought a Breville Smart Grinder Pro (highly recommended).
Has anyone used this grinder before, and if so what grind size would be the best for cold drip? Thanks
It is really preference, however, I have found that too fine of a grind (like espresso) will usually muddy up a filter and make it harder to pass through due to the lack of pressure. I am sure there is a setting guide either that comes with the box or online that you can use for drip/cold drip. Just remember to keep it coarse enough so that it does not come out too "powdery".
Edit: My recommendation is to use the "Drip Grind" coarseness. That means, a grind that is not as powdered down as espresso; grinds should be no larger that ~1-1.5mm in diameter. Usually the finer a grind is, the more pressure is needed to account for the surface area created.
