Claesson Koivisto Rune refines the Champagne glass

Stockholm studio Claesson Koivisto Rune has teamed up with a Champagne expert to design a version of the classic glass flute.

Claesson Koivisto Rune worked with Swedish Champagne writer Richard Juhlin to create a glass with a taller profile and larger volume, designed to form an optimum air-liquid ratio to capture the aromas of the sparkling drink.

"To design under the strictest parameters is the hardest thing," said the studio's founders, Mårten Claesson, Eero Koivisto and Ola Rune. "Refining and perfecting are your only available tools. We know the champagne world is taking this design to its heart. But will the design world, hungry for visual thrills, get it?"

The size and shape of the glass bowl's upper section is designed to concentrate the scent of the champagne.

The aroma is intended to rise from the liquid in the widened lower portion and collect below the rim, which is smaller in diameter than traditional flutes.

The curve of the bowl, from the stem to its widest circumference, is shaped to reduce the amount of liquid volume at the bottom of the glass while maximising the proportion of the Champagne exposed to the air.

This allows for the maximum amount of bubbles, which carry the scent, to reach the surface "without them getting bigger and less refined".

Designed to accommodate four fingers along its length, the stem is manufactured to be as thin as possible.

"The stem and foot act as a physical and visual counterweight to the bowl," said the designers.

The glass is available with a "Juhlin line", a thin marking around the bowl that the expert recommends as an ideal fill level.

Manufactured by Italian brand Italesse, the Richard Juhlin Optimum glass was launched at Chateau Les Crayères in France's Champagne region earlier this week.
