the following crus to create its blends: Grande Champagne, Petite Champagne, Borderies and Fin Bois. The harvest season begins in October, followed up by distillation from November to March. Courvoisier cognac is aged in barrels handmade from 200-year-old oak sourced from the Tronçais forest in France. Courvoisier headquarters are still stationed in Jarnac, about ten minutes from the Cognac region. Courvoisier is run from the original Château Felix Courvoisier and Jules Gallois moved to in 1828. Today, the Courvoisier Château has a boutique and museum, offering private tastings and exclusive tours. The museum features several items linked to Napoleon I. Marketing Courvoisier launched the Josephine bottle in 1951, named after Napoleon's first wife. The shape of the bottle, with a thin neck and wide base, has become synonymous with Courvoisier, and speculation still exists whether the shape is meant to mimic Josephine's love of corsets or an inverted replica of early brandy glasses. Courvoisier was the first cognac brand to appear on TV with an advertisement on UK television broadcast to nine million viewers. In 2009, Courvoisier was the first alcohol brand to release a 3D advertisement, titled "Cognac With Another Dimension", on TV and in cinemas, ahead of the viewing of the biggest-grossing film of all time, Avatar. A special iPod app was created to teach consumers how to use Courvoisier as an ingredient in cocktails as part of the "Mixability" promotion. In 2009 Courvoisier created an "Architectural Punchbowl" in conjunction with Bompas & Parr. It was intended as immersive brand experience, featuring cocktails served from a structure filled with 4,000 litres of a punch containing Courvoisier. The event was a homage to Admiral Edward Russell, who in 1694 created a large punchbowl that had to be served by a boy rowing across it. Le Nez de Courvoisier, one of the first examples of sensory marketing, recognised the dominant aromas in each of the Courvoisier cognacs and used them to deliver food pairing initiatives in partnership with leading chefs and music. In 1988, famed Art Deco designer Erté was commissioned to create limited edition Courvoisier bottles containing Grande Champagne cognac dating back to the year of his birth, 1892. The seven unique designs represented various stages of the cognac distillation process interpreted by Erté's unique designs. Courvoisier's next fashion partnership was in 2005 with English designer Vivienne Westwood. Sold exclusively at Harvey Nichols, The Courvoisier XO dressed by Vivienne
