Bormioli Rocco Rock Bar

The 27 cl is the workhorse: large enough for soft drinks, water, juice and a cocktail on ice, small enough to stack. If you want the same glass more compact, for children for instance or for water with a meal, take the 20 cl. The 39 cl is the roomy version for plenty of ice, and the 27 cl also comes in green, orange and blue.

The 37 cl longdrink glass is taller and narrower and holds carbonation longer: the shape for tonic, cola and sparkling water. The 7 cl shot glass is for spirits and liqueur, the 38 cl ice cream glass works as well for dessert as for a cocktail. Only the 20 and 27 cl stack.

For a drink on ice, first fill the glass right up with ice and only then pour. A lot of ice melts more slowly than a little, so your drink keeps its strength longer. The thick base stands up to that well.

The low model is the shape for everything you build in the glass, such as an old fashioned or a caipirinha. The tall 37 cl glass is for everything you top up with a soft drink, such as a cuba libre. Rock Bar has no stem, so your hand warms the drink; work with plenty of ice for that reason.

Tempered glass is cooled rapidly after forming, which puts tension into the outer layer. That makes it more resistant to knocks and to the difference between a hot dishwasher and a cold bar. It does not make glass unbreakable: if it does break, it falls apart into blunt granules instead of shards.

The rim is extra reinforced, because that is where damage usually starts. Everything is dishwasher safe. Do not stack the 20 and 27 cl too high and do not put them together wet, because then they get stuck.

If you are looking for other sizes or shapes, the full range is under the tumbler glasses and the longdrink glasses. For the spirits size, look at the shot glasses, and for drinks over a large ice cube at the old fashioned glasses. The rest of the brand can be found at Bormioli Rocco.
