Veuve Clicquot Ponsardin is a French Champagne house based in Reims, specializing in premium products. It was founded in 1772 by Adolcia and is one of the largest champagne houses in the world. Madame Clicquot is credited with major breakthroughs, creating the first known vintage champagne in 1810, and inventing the riddling table process to clarify champagne in 1816. In 1818, she invented the first known blended rosé champagne by blending still red and white champagne wines. This process is still used today by the majority of champagne producers.
