Flutes up: London's champagne rooms, and the nights that earn them

01The glass that marks the moment

No other drink carries so much meaning before it has even been tasted. Champagne is how people mark launches, anniversaries, signed deals and first meetings, and the sound of a cork easing out of a bottle still makes a room turn its head. Order a glass and you are telling the evening, quite plainly, that it matters.

That is precisely why it is worth choosing well. A champagne room is not simply a bar that happens to sell champagne. It is a place that takes the ritual seriously, from the temperature of the bottle to the shape of the glass, and knows which nights call for bubbles and which call for something else entirely.

02What makes a champagne room serious

Before you settle into a velvet chair, look for a few telling signs:

03Where London pours with intent

In Mayfair, the grand hotel bars are the natural home of a serious glass. Claridge's Bar, the Rivoli Bar at The Ritz and the lounges along Park Lane will all open a fine bottle with the appropriate ceremony, and their lighting is made for a toast. A glass here, before dinner or instead of it, is the classic Mayfair way to begin an evening.

Further afield, a few rooms have made champagne their whole personality. At Bob Bob Ricard in Soho, each booth carries its own button labelled press for champagne, and a waiter answers it with a bottle within moments. At St Pancras, Searcys runs a famously long champagne bar beneath the great iron and glass roof of the station, a glamorous welcome for anyone stepping off a Eurostar from Paris or Brussels. Both are proof that a glass of bubbles can be theatre as well as a drink.

Whichever room you choose, a little ceremony at the first glass is part of the pleasure. Wait until both glasses are poured, raise them gently rather than clashing crystal, and look at each other rather than at the bubbles; an old superstition holds that looking away brings bad luck. Then take the first sip slowly. The best champagne rooms leave you alone for a minute after the pour, precisely so that moment belongs to the two of you.

04When a flute is the right call

Champagne is a wonderful choice for some evenings and a slightly odd one for others. These are the nights that earn it:

05And when to choose something else

For a long dinner with rich food, a still wine chosen by the sommelier usually serves the meal better, as we explain in letting the sommelier lead. Very late in the evening, many people prefer a digestif or a simple nightcap, when a fresh bottle of fizz can feel like starting the party again. And if your companion prefers something else entirely, the best champagne rooms make a fine cocktail too.

There is also the question of pace. A glass of champagne at the start of an evening lifts the mood beautifully, but a whole bottle before dinner can make the table feel like the end of the night rather than the middle. Two glasses each, then a change of drink with the food, is a rhythm that keeps the whole evening bright.

06Glass, bottle or magnum

A standard bottle pours around six glasses, which makes it the natural choice for two people who plan to stay a while. For a one-hour meeting, ordering by the glass keeps things light and lets you try two different houses. Half bottles are rarer but lovely when you want just a little more than a glass each.

A magnum, twice the size of a standard bottle, is a statement for a celebration with friends, and wine lovers claim champagne ages more gracefully in the larger format. For two, it is probably generous; for a party in a suite, it is perfect.

07Grower, house and vintage, in a sentence each

The great houses of Champagne buy grapes from many growers and blend them into a consistent house style, year after year. Grower champagnes are made by the families who farm the vines themselves, often in small quantities with plenty of character. Non-vintage bottles blend several years for consistency, while vintage champagne comes from a single year good enough to be declared. Blanc de blancs is made only from Chardonnay, lighter and more precise; blanc de noirs comes from the black grapes, Pinot Noir and Meunier, and tends to be richer.

08Raising a glass with the right person

Champagne is best shared with someone who enjoys it properly. Nora, honey blonde and full of spirit, has a real palate for it and a preference for small grower houses over famous labels, and she will suggest the unexpected bottle on the list. She belongs to the blondes edit. Tiffany, with her long chocolate hair and a shimmer of sequins, loves the ritual as much as the taste: the pour, the toast, the first cold sip.
