Globalization of wine Globalization of wine Globalization of wine is the expansion of wine varietals and brands across nations and to other continents, especially in modern times as a result of the advent of air travel and access to wine information via the internet. Wine has been traded internationally since ancient times. In the wake of the amphoras came professional winemakers, winemaking techniques, and cuttings of grapevines. Many grapes that are considered 'traditional' in Western Europe were in fact brought by ancient trade routes from the Eastern Mediterranean and the Black Sea region. The Phoenicians, the Greeks, the Romans, the Armenians all brought
Leyden jar used in demonstrations. The jar is constructed out of a glass cup nested between two fairly snugly fitting metal cups. When the jar is charged with a high voltage and carefully dismantled, it is discovered that all the parts may be freely handled without discharging the jar. If the pieces are re-assembled, a large spark may still be obtained from it. This demonstration appears to suggest that capacitors store their charge inside their dielectric. This theory was taught throughout the 1800s. However, this phenomenon is a special effect caused by the high voltage on the Leyden jar. In the dissectible
