The annual celebration of champagne is set to take over the country from October1-7, and will be bigger than ever before, with 19 venues hosting more than 20 events across London, Birmingham and Bath. Ten Champagne houses will be lending their weight to the festivities.

Champagne houses taking part include Perrier-Jouët, Veuve Clicquot, Besserat, Moët & Chandon, Lanson, Tattinger, Mumm, Laurent-Perrier, Ruinart and Duval Leroy.

There will be tastings, masterclasses, brunches and discussions such as the rise of rosé.

A range of venues including Europe's longest champagne bar at St Pancras Grand, the iconic Gherkin and recently-opened Shoreditch hotspot Tonic & Remedy will be taking part. Participating venues outside London include the Pump Room in Bath and champagne bar and restaurant in Birmingham's Selfridges in the Bullring.
