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 over ice, fill the glass completely with ice first, then pour. A lot of ice melts more slowly than a little ice, so your drink stays at the right strength longer. The thick base helps prevent that.

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

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.
