Reddit mentions of New World Guide to Beer

I don't think the truth of my claim and /u/Mutand1s post are not mutually exclusive. I wasn't referring to whether the beer had this mythic provenance so much as the taste of that beer you call IPA is one that will hold up to heat and I think there is a difference. The story about developing this special formula for the voyage sounds a little too clever by half considering that climate and other conditions were the reasoning behind every style of beer.

Brewing, like baking is science as much as art. Humidity, heat and altitude will effect your bread and your beer. This whole thing about inventing a beer is probably a bit overstating things because if your making beer that will go in the hull of a ship sailing for months through the tropics you know that heat will be a factor and you would choose a traditional style off the shelf to meet your needs. Since you are a brewer; you might even add your own twist but that's just it right, you start off with something that has been refined for years and years and you might tweak it a bit with more fermentable sugars but it's mostly still the style someone has been drinking for years.

If you think about it a little bit though this is a question that can seem more obvious as you drill down. The history of brewing, like baking is one of refinement and an effort to bring consistency. There is a reason we arrive at Wonder Bread and Budweiser in the 20th century. These are two very refined and difficult to realize pinnacles of their craft that reflect the eras obsession with science and industrialization to create millions of items that are exactly the same and transparent enough to reveal flaws, remember this is the era that brings us Six Sigma. Try and brew a Bud/Miller/Coors beer or bake a loaf of Wonder at home and you will see how incredibly hard it is. Make fun of them all you want but these two foods were the subject of thousands of years of intellectual evolution.

Which brings us to why an IPA is hoppy and a little stronger than its counterparts. Someone mentions in this conversation that the beer was simply adapted from an existing traditional style, which makes sense. You take into consideration what the characteristics of the voyage will be and you come to the conclusion that a beer that holds up to summer is your recipe.

If you look at German and English styles that are brewed to stand up to summer heat and they tend to be stronger and hoppier than the beers made for other seasons. This is because hops, in general, was added to do a few important things for beer, stabilize flavor and mask off flavors (go to the end of page 262 in the link). High heat is no friend to beer that is sitting in a barrel and higher alcohol and hops is there to help counter and mask the effects. As a historical matter this is what hops is introduced for, make beer taste better under various conditions, help the brewer to attain a level of consistent quality.

Certain yeasts can help too, ale is better for warmer temps than lager. So you pick a hoppy beer brewed to stand up to summer heat for an ocean voyage. Whether or not that was some intricate formula or just an off the shelf solution is an interesting debate, but not the whole story. As you can see from just about any book on brewing history and styles, From Michael Jackson's World Guide to Beer to Charlie Papazian's The Complete Joy of Home Brewing you will see that styles came about as a result of the conditions for which they were brewed. Bud/Miller/Coors are brewed the way they are because of the technology that allows for strict and precise measurement throughout the manufacturing/brewing process. Ale is more forgiving and IPA is probably the most forgiving style for a new brewer to make because you can screw a lot of stuff up and still get it right. That's also the reason why that kind of beer is ideal to sit in the hull of a ship until you get to India.
