Amongst the oldest cultivated plants that are used primarily for drink are grapes (Vitis vinifera). The earliest documented evidence proving that grapes were cultivated to make wine dates to 6000 BC in Mesopotamia (modern-day Iraq), however the earliest physical proof of wine being stored and drunk comes from pottery excavations made in 1968 in Iran and dating to c. 5000 BC. But it was the ancient Egyptians, in 3000 BC who first recorded the process of winemaking, known as viticulture.Another plant that has been cultivated for thousands of years, specifically for drinking is tea (Camellia sinensis), of which the leaves have been used to make a beverage for 2-3,000 years. History dates the earliest use of it to 2737 BC, when the Chinese Emperor and herbalist, Shen Nong chose to drink his boiled water, even though leaves from a nearby camellia tree had accidentally fallen into it.
