Onis New Era

Let your choice be guided by what should go in the glass. For gin and tonic, the 59 cl copa beats every highball glass: the more ice it holds, the more slowly it melts and the less your drink becomes diluted. For whisky and a Old Fashioned choose the 26 cl tumbler, which holds exactly one large ice cube plus 6 cl of liquor. The 35 cl tumbler is the standard water glass at the table. The 47 cl highball glass is intended for mixed drinks with lots of soda and ice, while the 35 cl version is for juice and beer.

First fill the coupe completely with ice cubes, pour the gin over the ice, then pour the tonic down along a bar spoon so that the carbonation stays in. Stir once, no more. Garnish with whatever the gin evokes: a strip of lemon peel, a sprig of rosemary, a few juniper berries. Chill the 22 cl coupe and the 18.5 cl martini glass in the freezer, as there is no ice in them to keep the drink cold.

Onis makes these glasses from tempered glass, which means the rim has been heat-treated and stands up to knocks better than ordinary soda-lime glass. You notice it in the dishwasher: the rims chip less quickly and the glasses stay clear for longer. Do give the copa its own spot in the basket, because the wide bowl catches water on the foot and that drop is the last to dry. A short rinse cycle with soft water prevents a limescale haze.

All sizes for this serve are grouped under gin and tonic glasses, and you can find the rest of the brand’s range at Onis. Anyone using the martini glasses for an Espresso Martini will also need a cocktail shaker . For coupes in other sizes, see champagne coupe glasses, and for straight models alongside the copa, see the highball glasses in all sizes.
