APAX Mineral Drops offer complete solutions to optimizing water chemistry for coffee. They’re great if you want to take the guesswork out of creating or enhancing water recipes.

The APAX CORE BOX SET offers three formulas:

-Tonik: adds vibrancy and acidity
-Lylac: highlights florals and adds elegance
-Jamm: enhances sweetness and ripeness

KONFLUX, the newest Apax formula, was devised for the 2025 World Brewers’ Cup. It enhances mouthfeel and lusciousness in coffee, and is my favorite formula. 

I’ve been selling Lotus Drops for years, and I love them for being able to target and fix weaknesses in water chemistry. With Lotus, you can build from the ground up. If your water lacks magnesium or chloride, you can use the MgCl drops for targeted improvement. I’ve learned a ton about water and coffee using Lotus Drops. 

Apax concentrates are more like preformed solutions. Each bottle of Apax is a mix of similar ingredients, but in different ratios. They offer less learning and targeting, but an easier “add jamm to enhance the ripe, berry flavors in this coffee” approach.
