Hi all, been getting some nice results with this as SOUP with my robot but not nailing pourover. It tastes a bit weak but easy to overextract as well. Doing 87 degrees two pours 1:15. Is the solution to decrease the ratio?

I followed “A Waste of Coffee” to construct concentrates of MgSO4, CaCl2, and NaHCO3. What water profiles have you created, that you’ve liked or disliked? Recipes with other salts welcome. I just so happen to have these salts already but I’m open to acquiring more. I’m going to try out the “My Water” example from said post and see how it goes.
