Note: Buffer alone is not a complete mineral profile. Newcomers, please purchase a concentrate set instead. This product is sold separately in case extra is needed.

Buffer reduces acidity and general intensity of brew water. It can also help to reduce harshness, i.e. bitterness and astringency. The amount of buffer used will impact body and aftertaste as well.

Silica

empirical water is the first coffee water on the market to incorporate silica, a mineral that occurs naturally in many of the world's finest mineral waters.

Silica boosts sweetness, mouthfeel, and aftertaste.

Some describe the silica sensation as experiencing the sensory characteristics of your brew in slow motion. Aromatics stick around in your nose, mouth and throat for minutes on end.

If selected, silica will be added to your Hardness concentrate.

Silica not suitable for use in coffee machines.
