The PROPEL espresso glass takes a different approach to the usual "just make it double-walled" espresso glass: it's built to actively fix a real problem with espresso rather than just look good holding it. Because espresso is oily and can separate into different tasting layers as it sits, PROPEL uses three internal fins and a convex-shaped base — swirl the glass in your hand and it agitates the shot, de-stratifying those layers so what you taste in the last sip matches the first.

Each 2.5oz (75ml) glass is hand-blown borosilicate, double-walled at the base tapering to a single wall at the thin rim — cool to hold, keeps the shot at the right temperature, and the wider mouth gives the aroma room to open up as you drink. Comes in a Single or a Two Pack Set.

Who it's for

Straight-shot espresso drinkers who want to taste the shot as intended rather than as an afterthought to milk drinks — the swirl-and-sip ritual genuinely does even out flavour on an oily, separating shot. Less relevant if you're primarily a milk-drink drinker; the IMAGINE glasses are the better fit there.
