Beginner’s Guide to Home Brewing – Sediment

Care is taken to siphon mostly the clear liquid and not the settled cold break. I do allow some of the sediment, mostly toward the end, since it is unavoidable and actually has certain nutrients that can be utilized by the hungry yeast. Using all the sediment would give the yeast the option of feeding on that instead of the available Oxygen and creating off-flavors.

As we rack the wort I’m adding the yeast starter to get the yeast into the sterile wort as soon as possible so it can get acclimated and begin to go to work and prevent a lag period where foreign microbes can take over and ruin the flavor. The yeast have a big job ahead and initially require a large supply of Oxygen. For that I’m going to inject pure Oxygen into the wort and shake to aerate.

This process could also be accomplished by setting up a new aquarium pump with tubing and an aeration stone. This is the only time when aerating is good for wort and in fact is a necessary step for healthy yeast production. After the Oxygen is taken up by the yeast the fermentation will take place in an anaerobic environment where Carbon Dioxide, alcohol and a slurry of other chemicals are produced. If not using oxygen the carboy must be shaken quite thoroughly to aerate it well enough to get the yeast going quickly, usually a good 10-15 min.

When finished cap with the three-piece airlock filled with 1 inch of vodka.

Count on spending about 4-5 hours from start to final cleanup.
