Waga Brewista Ratio Scale
Brewista's innovative Ratio Scale allows users to make perfect pour over coffee by pacing the amount of water to pour. The scale automatically calculates the water needed based on the amount of coffee grounds used and chosen ratio. Dual timing bars display the actual and desired pour rates. Matching the timing bars achieves the recommended 2½ minute pour time. The Ratio Scale makes a perfect training tool for baristas and coffee lovers alike that want to get their pour over coffee dialed in. It features automatic and fully manual modes, and the water to grounds ratios are adjustable. The Ratio Scale takes care of the math so you can take care of the customers!
