Active Beer Yeast Video – 400x Magnification

The following video shows American Wheat Ale yeast in active fermentation. The yeast was taken from the krausen of a beer that had been fermenting for a week. If you expand the video to fullscreen and look closely at the 400x magnification segment of the video, you will see yeast activity where small black specs are moving around inside of the yeast cell walls.

The video continues on to show the yeast at 100x and 40x magnification to give you an idea of just how many yeast cells there are on such a small glass slide. An active 5 gallon beer fermentation should have well over 10 billion active yeast cells during primary fermentation.

2-Row Crushed Malted Barley Under the Microscope

Below is a video of a two-row malted barley grain shown under the magnification of a microscope. The video allows you to see a closeup of the structure of the grain. The footage was taken under approximately 100 power magnification.
