The new Espresso Parts' espresso shot glass has been designed with a 1 oz indicator line and a 1.5 oz indicator line.

This shot glass has a 2 oz capacity to the top. The squared shape allows the barista to seamlessly line up two shot glasses side by side for measuring espresso extraction from double portafilter spouts.

The opening is 1-5/8" wide inside straight across, but 2" across inside diagonally and 2 and 7/16 inches tall.
