Dose partnerThird Wave Water
Water is most of the cup — and the part almost everyone brews wrong. Third Wave Water is mineral chemistry in a stick: drop one into a gallon of distilled water, shake, and brew on a profile engineered for your roast instead of whatever came out of the tap. The espresso profile is the quiet upgrade under a great shot.

Why water
Nine-tenths of the shot
Espresso is ~90% water. It is the biggest ingredient in the cup — and the one almost nobody dials in.
Three minerals, on purpose
Magnesium drives extraction, calcium builds body, bicarbonate keeps acidity in balance. A profile is those three, weighed.
Repeatable by design
Distilled water is a blank slate. A measured mineral stick makes every gallon identical — same water, same shot, anywhere.
