One thing that can affect the quality of your brew is fermentation loss, which happens when some of your beer gets absorbed by the yeast during fermentation.Let’s talk about it below，What are the factors that reduce beer fermentation?
One of the biggest mistakes you can make when it comes to fermentation is using a low quality brewer’s yeast. This will not only result in increased beer loss, but can also cause off-flavors and affect the appearance of your brew.Use a high quality starter culture or fresh dry yeast that was packaged within the last six months for best results. If you are using liquid yeast, make sure it has been stored correctly (at between 59°F and 72°F) with plenty of oxygen so that it is not stressed out before pitching into your fermenter. It is also important to note that different strains have different optimal temperatures for activity; if you are unsure which strain will work best with your desired style or process temperature range, consult an experienced professional before making any decisions!
Pitching enough yeast is important to ensure that your beer ferments completely and cleanly. If you pitch too little, the fermentation may stall or stop before reaching terminal gravity (SG). In this case, you will have a thick layer of yeast at the bottom of your fermenter that can cause off-flavors in your beer.
If you find yourself with an active fermentation but it’s not going as quickly as expected or if there are signs of contamination—such as bubbles in the airlock or signs of mold growth on the surface of your wort—it may be time to dump out some unfermented wort and pitch fresh yeast. If you don’t have access to another culture, use canned liquid malt extract from which any bacteria has been killed by boiling it first before measuring out into a sanitized flask; do not use boiling water from a kettle as an alternative because this could also kill any desirable yeasts present on your equipment.
