Wine can be collected both for enjoyment of drinking and as an investment that appreciates over time. When collecting wine, quality, price, producer, and vintage year are most important factors. Winemaking and collecting has a long history dating back thousands of years to ancient Egypt and Rome. The advent of cork stoppers and glass bottles in the 17th-18th centuries allowed for proper aging and transport of wine. Today's market offers opportunities to collect both established wines and new discoveries, though conditions for cellaring and future demand are unpredictable.
