The temperature to ferment beer in a pressure tank depends largely on the type of beer being fermented. For most ales, the ideal temperature range should be between 65-72°F (18-22°C). Lagers and some wheat beers may require a few more degrees and can ferment as high as 75-80°F (24-27°C).
Pressure tanks also allow more oxygenation which can help get a more consistent fermentation profile as it adds more yeast activity and agitation in the fermentation vessel. When using a pressure tank, it is important to monitor the pressure and temperature levels closely as the pressure can vary significantly within the tank depending on the temperature and rate of fermentation.
Pressure can be set through regulating the atmospheric pressure or moving the tank up higher or lower on the fermentation stand. Also, you can use a Fermtech airlock or CO₂ stone to help release pressure at the same time as oxygen gets transferred into the tank.
Generally, it is recommended to check the pressure every couple of days and if the tank is not properly ventilated, it can cause over-pressurization.

What pressure should I ferment lager at?
The first is the desired carbonation level. The second is the temperature that the lager will be fermenting at. The higher the temperature, the higher the pressure should be. The last thing to consider is the type of lager yeast being used.
Some lager yeasts are more tolerant to high pressure than others.
In general, you should ferment lager at a pressure that is 1-2 psi higher than the desired carbonation level. For example, if you want your lager to be 2. 5 volumes of CO2, you should ferment at 3. 5-4.
5 psi. This will ensure that the lager is fully carbonated.
The temperature that the lager is fermenting at will also affect the pressure. The higher the temperature, the higher the pressure should be. This is because higher temperatures create more CO2. For example, if you are fermenting your lager at 60 degrees Fahrenheit, you should ferment at a higher pressure than if you were fermenting at 50 degrees Fahrenheit.
The type of lager yeast being used is also a factor to consider. Some lager yeasts are more tolerant to high pressure than others. If you are using a lager yeast that is not very tolerant to high pressure, you should ferment at a lower pressure.
How do you ferment lager under pressure?
Lager is fermented under pressure to prevent the carbon dioxide from being released from the beer. This process is called pressure fermentation. The pressure fermentation process is controlled by the temperature of the fermentation vessel.
The vessel is cooled to a temperature that is lower than the temperature of the surrounding air. This allows the beer to ferment under pressure and prevents the carbon dioxide from escaping.
Is pressure fermenting worthwhile?
Yes, pressure fermenting is definitely worth it! It’s a great way to create delicious, carbonated beverages without all the mess and hassle of standard fermentation. Plus, it’s much faster than traditional fermentation, so you can enjoy your drinks sooner!.
When should you spund a lager?
Typically, lagers are spunded when they are between 5 and 8% ABV. This allows for a slight amount of fermentation to occur in the bottle, which results in a slightly higher level of carbonation.
Do you need an airlock for fermentation?
No, you don’t need an airlock for fermentation. Fermentation is a process that happens without air. However, if you’re fermenting in a vessel that’s open to the air, you may want to use an airlock to keep out bacteria and other contaminants.
How much pressure can a carboy take?
A glass carboy can typically take up to 5 psi of pressure, but it’s important to use a blow-off tube with any pressure over 1 psi. Higher pressure carboys made of PET plastic can take up to 15 psi.
Can you open lid during fermentation?
Yes, you can open the lid during fermentation, but it’s not recommended. Fermentation is a process that produces alcohol and carbon dioxide, and if you open the lid, you’ll release some of the carbon dioxide.
This can affect the taste and quality of your beer.
Do I put the cap on my airlock?
Airlocks should not be sealed with a tight-fitting stopper. The purpose of the airlock is to allow carbon dioxide to escape while keeping air and contaminants out of the fermenter. If the airlock is sealed too tightly, carbon dioxide will be trapped in the fermenter and put too much pressure on the lid, potentially causing it to blow off.
Can I use a balloon instead of an airlock?
A balloon can be used instead of an airlock, but it is not as effective. An airlock allows gas to escape while keeping oxygen and other contaminants out. A balloon will allow some gas to escape, but it will also allow oxygen and other contaminants to enter the container.
What PSI should I ferment under pressure?
Such as the type of beer you are brewing, the type of yeast you are using, and your personal preferences. Some brewers will ferment under pressure to help control the fermentation process and to produce a clearer beer, while others will ferment without pressure to allow the yeast more freedom to work.
Ultimately, it is up to the brewer to decide what PSI to ferment under based on their own experiences and preferences.
Is fermentation faster in pressure?
Yes, fermentation is faster in pressure because it allows the yeasts to produce more alcohol. This is due to the increased pressure forcing more sugar molecules into the yeast cells, which leads to a higher rate of fermentation.
Should you dry hop under pressure?
Dry hopping under pressure is not recommended as it can cause the hops to become more vegetal and grassy in flavor. It can also cause the beer to become more astringent.
How long should beer sit after fermenting?
It is generally recommended that beer sit after fermenting for at least two weeks, and up to two months. This allows the beer to properly carbonate and develop its flavor.
Should I stir my mash while fermenting?
While you don’t need to stir your mash while fermenting, many brewers believe that it’s beneficial. Some say that stirring helps to evenly distribute the yeast, which can lead to a more controlled and consistent fermentation.
Others believe that stirring oxygenates the wort, which can lead to a healthier fermentation. Ultimately, it’s up to you whether or not to stir your mash while fermenting, but many brewers find that it’s helpful.
Can you ferment beer for too long?
Fermenting your beer for too long is likely to cause off-flavors and diminished quality. If your beer has been fermenting for longer than the recommended time, we recommend that you collect a sample for testing.
You can take a hydrometer reading at regular intervals to determine if fermentation is still active.
Can you bottle straight from the fermenter?
Yes, you can bottle straight from the fermenter. This is called racking. Racking is the process of transferring your beer from the fermenter to a container for storage or serving. Some people rack their beer into bottles, while others rack into kegs.
Racking is generally done with a siphon, although some people use a pump.
Does longer fermentation mean more alcohol?
There is a general trend that the longer a fermentation process takes, the higher the alcohol content will be. However, there are many other variables that affect the alcohol content of a fermentation, so longer fermentation is not necessarily a guarantee of a higher alcohol content.
Can you over ferment?
Yes, you can over ferment, and it’s not a good idea. It can happen if you let your beer ferment for too long, or if the temperature is too high. Over fermenting can make your beer taste sour, and it can also cause your beer to be cloudy.
Can I bottle my beer if it’s still bubbling?
It is not recommended to bottle your beer if it is still bubbling. This is because the beer will continue to ferment in the bottle and the carbon dioxide produced will cause the bottle to explode.
