As Damase has already informed, yesterday was a double brew day. After a total of three batches, Pozharnik is finally in the tank and already rocking!
For those of you have not been on a brewery tour or haven't homebrewed, when yeast is supplied with a sugar source (wort) they start consuming the sugars for growth and survival. This is what we call fermentation. When the yeast eats up sugar it creates two byproducts, CO2 and ethanol. During the first days of fermentation (Primary fermentation) there is a large volume of CO2 being released. If a fermentation tank did not have any means of rapidly releasing the CO2, the tank would build up pressure and possibly explode. This is why we have what is called a "Blow-off" hose. It is just a simple hose coming from the tank into a bucket filled with water to create an airlock but easily allow the CO2 to escape. When fermentation becomes visible, the water in the blow-off bucket will start to violently bubble. This is what we call "rocking."
Leaving the brewery around 8:45PM or so, all you could smell was the sweet smell of freshly brewed wort and vanilla balanced with the subtle scent of espresso.
