Chicago police accused of planting evidence in ‘Molotov cocktail’ plot

16. That looks like a nice Krausen on the left, the smaller, several gal bottle

It also appears to be a dark beer being brewed. Hard to say how long until it's ready, but the Krausen happens within a few hours to a day after pitching the yeast. It only goes for a day or two, then the "blow off" settles down, and fermentation continues but at a somewhat slower pace.

You'll note the tubes coming out of the top go into a plastic container sandwiched between the two fermentation bottles. That container is filled with water, and the hose ends are submerged. That is the airlock, any blowoff from the Krausen ends up in that water. With a vigorous fermentation and lots of blowoff, that water will become slightly colored with minor amounts of yeast and wort. The airlock prevents oxygen from getting in the headspace of the bottle, so once fermentation begins and CO2 is being produced, the CO2 displaces any air in the bottle, protecting the wort from oxidation. Oxidized beer tastes like a beer left in an open cup for a day.


This is as good an example as any of the dangers of not teaching kids in school how beer is typically brewed. Yah, I know nobody wants kids brewing their own beer, but kids turned adults may believe beer is only made in huge corporate factories by some mysterious, probably patented process, and shipped to the local merchant. Who the heck else would ever know how to brew beer. Corporate Beer is the only way to get beer!
