Beer, on the other hand, has always been the common man's drink; easily made from easily grown crops, so a volcano blowing up or a nasty little root-eating bug never decimated the industry as a whole. It has gone through some significant refinements (the backgrounds of which are really, truly, interesting), such as the introduction of hops as a preservative, which was mightily challenged by entrenched interests (big surprise).

Here's an overview of that battle: The usual additive to beer was a mixture of herbs called grut. The folks who sold those herbs tended to be powerful men (often Church officials) who held a monopoly on the local grut production (as well as most breweries), and they didn't want to give up that income. They lost out in the end only because they were trumped by economic reality: adding hops meant brewers could use less malt, which meant they could produce a lot more beer for a lot less money. Prohibitive laws and monopolies didn't stand a chance against that kind of incentive, and by the early 1400s, even King Henry VI was on board in favor of hopped beer.

Hops did bring more vulnerability to the beer industry, unfortunately, as this plant is very susceptible to a variety of bugs, diseases, and molds. So the introduction of hops, while a blessing for shippers and merchants who needed beer that wouldn't spoil in a week, did bring a fair amount of speculation and bust-boom-bust to the overall beer market from time to time.

For writers: What would happen if the main source of your culture's favorite booze went under from something like Phylloxera, or if a favorite additive was no longer available? Who would profit? Who would be bankrupt if they couldn't adapt fast enough? How would that change the economic landscape of your world?

Favorite drinks are like any other fashion in their fluctuations, but generally there's a reason behind the change that has nothing to do with some behind the scenes maven dictating the Taste of the Year. When one industry bottoms out, another always rises to take its place; so when wine almost went under (including brandy, which is just distilled wine), public attention in Europe switched over to distilled liquors such as whiskey and gin.

And gin almost killed England in the eighteenth century. A combination of factors was involved: a war that introduced English soldiers to Dutch gin, uneven taxes that made beer more expensive than gin, and a Dutchman sitting on the English throne set it all in motion, but the end result was that gin became the lowest-price bottle on the shelf. Or in the bathtub, for that matter, since one of the laws allowed home distillation; and if that wasn't enough incentive, distillers were exempt from having soldiers billeted on their household.

In "Alcoholica Esoterica," Ian Lendler notes: "In 1689, all of England produced about half a million gallons of gin. By 1733, London alone produced and consumed about 6 million gallons. In 1750, London consumed 11 million gallons. And here's the real kicker--at that point, London had a population of just over 600,000 people." He also points out that these numbers do not take into account the private, untraceable sales of gin from home stills around the city.

That population dropped sharply; three out of four children died before the age of five. Trying to impose taxes to restrict the consumption of gin resulted in riots. Banning gin caused riots and a flourishing black market trade. What would have happened if a drought hadn't intervened we can only imagine--and writers can gleefully play with. But a drought did come in, and with the main ingredients of gin (corn and barley), in scarce supply, gin scaled back to being popular but no longer a mad epidemic.

For writers: Addictions and addictive behaviors are a fact of human history and culture. What is the current intoxicant craze in your main fictional society? What is the government doing about it? Who is profiting by it? What started it, and what, if anything, will stop it? What addictive cycles have shaped your cultures? There will quite possibly always be tension between the descendants of rum-trade slavery and those of pre-Revolution American heritage; what sort of centuries-long tensions exist in your fictional world, and are any efforts being made to address them?

Once again, I find myself coming up against my self-imposed word limit with pages of information yet to cover. The sheer volume of information about the history of alcohol boggles the mind, and a 1500-word attempt to create an overview of any one aspect is doomed to be woefully inadequate. I can only hope that I've given some readers cause to look further into the excellent resources listed below, that I've given writers some ideas that help develop a robust fictional world, and that all my faithful readers come back for the next part of the series, which will look at the mythology and legends of alcohol.
