Part 15: Yeast and Flavor in Beer

This blog will soon post an audio diary on making beer with liquid yeast instead of dry yeast.

The liquid yeast used was White Labs' California Ale Yeast.

In doing research, a helpful article by Christohper White entitled "7 Fascinating Facts About Yeast" proved to be quite interesting.

Of the 7 interesting facts, perhaps the most interesting is that yeast provides most of the flavors and aromas in beer.

To an untrained brewer, taste could be thought of as coming from the variety of grains or hops that the brewer decided to boil with his beer. White says this isn't true.

All of the flavors already in the wort are changed by the yeast, adding 600 flavor and aroma compounds to the finished product.

"For example yeast change the way malt and hop compounds taste and smell," he writes. "Hops are affected because different yeast strains adsorb different amounts of iso-alpha-acids, which account for 60 percent of beer’s bitterness. Malt components are affected because they are metabolized by yeast."

Yeast does much more than produce the alcohol that makes beer worth drinking.

Part 13: The Beer Diet

Many people choose to give up drinking beer for Lent, a little sacrifice to hopefully better themselves for the Easter season.

Some people, however, take a different approach for those 40 days: a Beer-only fast.

This isn't something thought up during a 3 a.m. chat between two wasted frat brothers, but in fact goes far back 300 years when Bavarian monks would brew strong beer and give up on solid foods. Many people have done this fast since, included an editor of a German newspaper and an Iowa beer blogger.

Here's the CNN video:

The Iowa blogger says he lost 22 pounds during Lent.

Part Ten: Beer Stats

Home brewing and the brewing of craft beers seems to be a growing trend in the past few years. Here are some statistics from the Brewers Association and the Beer Institute:

The World of Beer Inforgraphic. Via Submit Infographics.

• Craft beer brewing provides for 100,000 jobs in the U.S. This stat seems more important with all the talk of jobs and job creators in the media and on the Republican primary trail
• Craft Brewing may be recession proof. In 2010 growth in the Craft Brewing industry went up to 11% by volume and 12% by dollars, a respective 1% uptick in both spots
• In 2011, 1,927 breweries operated in the U.S. The U.S. also added almost 200 breweries from the year before.
• 1979 was the worst year for breweries. The bumber of breweries dropped down to it's lowest point: 44 breweries.
• In 2010, American brewers made 19.5 gallons of beer for each American.
• In IL, there is a 75% tax credit for small breweries who put out less than 4.9 million gallons
