At C'est Bon Biere, we decided to start the year off with a brew day. January 1st began with the brewing of our first attempt at a lager. We decided to brew a California Common, also known as a Steam Beer. It is very similar to Anchor Steam, from the oldest craft brewery in America (they claim since 1896)! We are calling this one Common Sense, because everyone can use a little common sense in 2015.
In order to brew a lager, we needed two vital pieces of equipment: a refrigerator and the equipment to make a yeast starter. There are two broad categories of beer, ale and lager. Ales are top fermented and ferment at warmer temperatures, while lagers are bottom fermented at colder temperatures. We are currently using our kegerator to ferment the lager, and keep a constant temperature.
Even after three days, you can already see the result of fermentation in the glass carboy |

Usually, we buy packages of yeast from the homebrew supply shop, and pitch those packages directly into the wort. These packages, on the manufactured date, contain 100 million yeast cells. As the package gets older, the number of active yeast cells decrease. A yeast starter is essentially a small batch of beer that is made a day or more before the scheduled brew day in order to activate the package of yeast.
After a day of refrigeration, the yeast cells rest at the bottom of the flask, ready to be pitched into our brew. |
The yeast will become active and multiply in the sugary wort. After refrigeration, the yeast cells will settle to the bottom of the flask, ready to be pitched. For Common Sense, we pitched 65 million yeast cells into the starter, and two days later pitched 200 million yeast cells! The number of cells can be controlled based on the amount of starter wort made.
C'est Bon Biere is going to have a busy year, and we look forward to keeping you updated on our brews and educated on beer science and the growth of craft beer in the Louisiana. One of these days, we look forward to moving out of the garage, and become the first microbrewery in Gonzales, LA!
Coming up next, we plan on collaborating with a homebrewing friend of ours to make two beers for the upcoming homebrew competitions, a blonde ale and a saison. Our black IPA will also be entered in the competitions. More information to come when we get these recipes written, creative names are thought of, and the brew day starts.
Until then, drink local. Drink good beer. Cheers!
