Champagne is of course an essential component of Valentine's Day celebrations, and the world's oldest champagne house is doing its bit. Champagne Ruinart, founded in 1729 and now part of LVMH's luxury empire, is offering a special edition gift box set called "My Sweeter Half" (above) for the occasion. The gift box includes two half bottles of the famed French house's premium cuvées: Ruinart Blanc de Blancs (left) and Ruinart Rosé (right). The Sweeter Half set, priced at $85, also comes with a pair of Ruinart champagne flutes. Hint: this would go great with that lingerie from Agent Provocateur.
