You can learn important information in the history of wine in America.

Although Thomas Jefferson and others envisioned a United States of America with a thriving wine culture, the temperance and prohibitionist movements pushed the country in a very different direction. Mendelson traces the early development of viticulture in America, to the rising tide of Prohibitionism, culminating in the failed experiment of the Eighteenth Amendment, to repeal and the jumbled mess of state and federal regulation that followed, to the roaring growth of the wine industry since the 1970s. There is interesting discussion of the battle to define American Viticultural Areas and of recent case law that addresses interstate sale of wine. He concludes that there is still a long way to go before an "authentic wine culture" can take root in America -- with a rational system for the regulation of wine production and sales to go along with it.

It's a great read and includes an excellent bibliography for those who want to dig deeper.
