Beer fermentation stage-lag stage
Once the yeast is put into the wort, it will enter what we call the lag phase. Although there are no obvious signs of fermentation at this stage, something is still happening. Yeast is absorbing the oxygen in the wort and produces sterols, which is essential for the reproduction and healthy growth of yeast. So, what is yeast?
Yeast is a single-celled eukaryotic microorganism and is classified as a member of the kingdom Fungi. The first yeast cell originated hundreds of millions of years ago. At present, humans have discovered at least 1,500 yeast cells. The yeast cell is a living organism, so it needs oxygen to maintain vital signs. This is why aeration of wort is very important in commercial brewing. Yeast cells need oxygen to grow and produce important cell wall components. In addition, yeast cells need to absorb oxygen, and they also need some vitamins and minerals needed for growth.
In modern brewing processes, all the vitamins needed for yeast growth can be found in high-quality malt. If your brewing recipe contains a lot of additives, you may need to add some yeast nutrients during the boiling process to help the yeast work. A simple brewing trick is to add some inactive yeast from the cooled cone-shaped beer fermentation tank during the boiling process of the nearest 10 minutes from the fermentation. If the nutrients in the wort are insufficient, this will provide the yeast with the minerals and vitamins needed for a healthy fermentation.
It is a good thing that you do not understand any activity in the later stages of the fermentation process. Yeast cells are gradually adapting to the environment and establishing the necessary growth for a healthy fermentation. You can reduce the lag period by increasing the pitch rates of the yeast, but each yeast cell may not be very healthy at the end of the fermentation. Over time, each re-throw will affect the fermentation process. Therefore, do not over-magnify the influence of pitch rates on fermentation.

- Yeast used
- Pitch rate
- Fermentation temperature
Beer fermentation stage-stationary stage
Beer fermentation stage-conditioning stage
- Most of the yeast falls out of the beer (which can be dumped) making the beer clearer.
- Haze-forming proteins are formed and precipitate.
- The beer becomes “smoother” as harsh flavors mellow out or are reduced.
- There’s a reduction in sulfur compounds, diacetyl, and acetaldehyde.
- Overall flavor stabilization.
Simple fermentation plan
- Just before adding the yeast, record your initial gravity sample.
- Pitch your yeast and set the specified fermentation temperature.
- Use hygiene habits to record your gravity every day.
- If temperature control is available to you… When your gravity is within 2–3 points of the expected final gravity, raise the temperature of your fermentation 3–4 degrees celsius. This is very important for the quality of beer because it ensures that your yeast remains healthy and can clean up any undesired by-products produced during the fermentation process.
- Continue to record your gravity every day. When the gravity stays the same for 3 days, you can be sure that the fermentation is complete.
