Quoted:
Hmm... IPA or ales... tough call.
Technically, an IPA is an ale. The Brits, back in their glory days, found that getting good beer all the way to India was a bitch-tons and tons of spoilage (aw, fuck, who orderd 200 barrels of malt vinegar?). So, the India Pale Ale is what they came up with. Brewed to have a high alcohol content (to prevent spoilage), they also realized that hops also work as a preservative. Since beer was properly high on the list of shit that needed to make the sea voyage intact and unspoiled, they added a fuckton of hops as well. Which is good, because otherwise, IPA would be a high alcohol, sweet, cloying, nasty beverage. Because hops also have the beneficial effect of balancing the sweetness of the malt in the beer.
And that, boys and girls, is the story of how IPA came to be.
