Paleo Treats Water Skid
A water treatment skid being built for Paleo Treats (3275 Adams Ave, Ste A, San Diego CA 92116) to give their coffee shop a real competitive advantage on water quality.
The core idea: take any drinking water source — municipal, well, whatever — clean it down to a "blank slate" (TDS < 10 ppm via reverse osmosis), then precisely dose minerals back in to fully express the flavor of a given coffee. Eventually the skid will be productized and made available to other coffee shops.
Dosing minerals
- Magnesium Sulfate
- Calcium Chloride
- Sodium Bicarbonate
The system has to be robust, meet every regulating agency standard, and be easy enough that a barista with minimal training can use it day-to-day. It needs to produce both espresso water and pourover water on demand.
Aspects of water for coffee
- pH
- Hardness
- Alkalinity
- TDS (total dissolved solids)
