Luxury winemakers producing some of the most expensive wine in the world will pay up to $50,000 for a single barrel to age their wine. But not just any barrel — a foudre. A foudre is a massive wooden vat that impacts and preserves the overall taste of the wine.
A tourbillon (French for "whirlwind") is a centuries-old mechanism built inside some of the world's most expensive watches. It was originally designed to improve the accuracy of pocket watches by rotating the escapement and balance wheel to help counter the effects of gravity.
