So what is this “Yeast” thing anyway?

So what is this “yeast” thing anyway? Yes that stuff that is used to make bread and beer. It is actually a living cell, a single celled organism actually. Yeasts are actually a type of very small fungus. The type used in bread and beer and wine has a genus and species name, namely saccharomyces cerevisiae. The breakdown of sugars into carbon dioxide and ethanol (for our bread and beer) is part of its natural metabolism. Of course, we have learned to grow it in other media, which allows us to purify it and put in into packets that you can pick up to bake bread of make beer.

Now just to worn you, other fungi can cause problems. Saccharomyces cerevisiae probably won’t infect you like other fungus/mold could.

A Dozen, is it really twelve?

While discussing the baking of bread, I thought of a dozen rolls (a common serving for rolls). So you may have heard that a dozen is the number 12. The etymology (history of the word) indicates that (the English word “dozen” coming from the french “douzaine,” meaning group of twelve). However, ultimately a dozen can refer to any standardized grouping of things by a certain numbers. Balloonists are rumored to carry 18 balloons (for those who have seen King of the Hill), so 18 is a “Balloonist’s dozen.”

You may have also heard of a baker’s dozen, or 12 + 1 = 13. There are many different hypotheses behind this. Wikipedia has an article that suggests baker’s would need to weigh their rolls and in the event one was a tad light for customers they would add an extra roll (a type of insurance).

Bakers-Dozen

As yeast was used to leaven bread as mentioned in a previous post, prior to the ability to grow yeast independently through cell culturing, yeast was obtained from skimming the head of beer (as mentioned) or from taking a small uncooked portion of bread from a previous dough. Some hypotheses exist that the extra bit of dough to be used in making the next bread roll was added to the dozen rolls made from dough (this is still done in making sourdough bread). So perhaps this was the origin of a baker’s dozen.

Yeast, the same kind used in bread?

So from a previous post I mentioned microorganisms like yeast used to break down sugars to create ethanol, the alcohol found in beverages like beer. Now you might be thinking to yourself, yeast, the stuff used in bread?

Yes that is right, yeast which is used to leaven certain types of bread can also be used to make beer and wine. Bread has a long history (look up some good stuff on wikipedia) which relates to the making and production of beer. I have even heard beer called “liquid bread.” To some degree this makes sense as many of the same ingredients are involved. Foam was sometimes skimmed off the top of beer for use in making bread or small rolls of kneaded uncooked bread were used in beer and wine production (or to make more bread).
