How to Brew

Pressure Fermenting

I am new to pressure fermenting, what is the recommended pressure for fermenting?

Pressure fermentation allows for the suppression of some yeast ester formations. This means that the esters that would have been produced at higher temperatures can be supressed so temperatures can be raised to speed the fermentation process. We feel that the sweet spot for LAGER (spelled LARGER on most homebrew forums) fermentation is somewhere around 15psi or 1bar of pressure to help the beer remain crisp and help suppress the two no no’s in crisp lager which are banana and clove esters!

Higher pressures can be damaging to the yeast’s cell walls.

Ale fermentation, in general, seeks to nurture ester production so by keeping the pressure low, around 8 to 10psi, you’ll have virtually no detectable difference in flavour unless you’ve got a palate as sensitive as a gas spectrometer.

What is Apollo?

Apollo

Apollo is the highest evolution of the PET Pressure Fermenters and unitanks available in the world. Our PET tanks are the strongest in the world thanks to our patented Australian Made manufacturing process that ensures every single tank is individually pressure tested before sale. The handles on all Apollo tanks are strong enough to lift with even when the tanks are full of liquid and the stainless steel frames make it simple to orient your tank wherever you require. 

With our unique design and built in ergonomic handles, Apollo is stronger and easy to carry around.

What is the thermowell for?

The Termowell is a hollow, food grade stainless steel tube, that is closed at the bottom and in which you can insert the temperatur probe of your temperatur controller. Controlling your fermentation

Dry Yeast Usage

Is it recommended to rehydrate dry yeast?

A big part of homebrewing comes down to what works best for you and also following producers' recommendations. We would encourage you to read instructions before use.

Do I need to rehydrate the yeast before pitching?

Typically, dry yeasts do not need to be rehydrated before use and can be pitched directly into our fermenters. However, some brewers prefer to rehydrate dry yeasts as they think it speeds up the start of fermentation.

How do I rehydrate dry yeast?

To rehydrate yeast, simply add around 300ml of lukewarm water to a sanitised conatainer, and add the content of the packet then cover with a layer of tin foil. You will notice that after an hour or so, the yeast will start to buble and activate.

Storage Recommendation

How do I store my dry yeast?

Store in the fridge or dry and cool place.

How long can I store my dry yeast

Tins usage

How do I get the malt out of the tin?

You will need to open the tin and warm it up gently in a pot of water to help liquify all the malt goodness. Once the content seems runny enough, it is reday to transfer to your pot or fermenter.

How many tins do I need?

Most recipes call for 1 tin however the world is your oyster and you can experiment with 2 or even 3 tins! we recommend you take a look at our recommend tin or Kit & Kilo recipes.

Storage

How do I store my tin?

Similarly to all other food tins, in a dark and dry place such as a regular food pantry.

How long can I store my tin for before usage?

Every tin will have a best by use date on the bottom or top of the tin.

My tin has passed its best by use date, what do I do now?

Most people will discard the tin however some warriors have used them in the past and lived to tell the tale. There will be loss of flavour

What are hops?

Hops are the female flowers of the hop plant (Humulus lupulus). They are used in brewing to add bitterness, flavor, and aroma to beer.

How do I use hops in brewing?

Hops can be used at different stages of the brewing process. They can be added during the boil to impart bitterness, added toward the end of the boil for flavor and aroma, and used for dry hopping during fermentation to enhance aroma.

How much hops should I use in my beer?

The amount of hops to use depends on various factors such as the beer style, desired bitterness, and hop characteristics. Recipes typically specify the amount of hops to use, but you can also experiment and adjust according to your taste preferences.

How do I measure hops?

Hops are typically measured in weight, usually in grams or ounces. A digital scale is a useful tool for accurately

Can liquid yeast be shipped in the mail?
Absolutely! We will take great care of the packaging and ensure the yeast stays in as good condition as possible.

How should I best use liquid yeast in my brewing process?

Using liquid yeast in brewing can enhance the flavor and character of your beer. Here are some tips for optimal usage:

• Properly store the liquid yeast in the refrigerator before use.
• Plan ahead and prepare a yeast starter to ensure a healthy yeast population and a strong fermentation.
• Follow the instructions provided by the yeast manufacturer for rehydration or direct pitching into your wort.
• Maintain a suitable fermentation temperature to promote yeast activity and flavor development.
• Consider using a yeast nutrient or energizer to support yeast health and fermentation performance.

What are fresh wort kits?

Fresh wort kits are convenient and time-saving options for homebrewers. They consist of pre-made, ready-to-use wort (unfermented beer) that has been professionally brewed and then packaged for homebrewing.

How do fresh wort kits work?

Fresh wort kits eliminate the need for the homebrewer to go through the entire brewing process, including mashing and boiling. Instead, the kits provide a pre-boiled and cooled wort that can be transferred directly into a fermenter, where yeast is added to begin fermentation.

What are the benefits of using fresh wort kits?

Fresh wort kits offer several advantages, including:

• Time-saving: With pre-made wort, you can skip several hours of brewing and focus on fermentation and other aspects of brewing.
• Consistency: Professional brewing ensures a high-quality and consistent wort base for your beer.
• Convenience: Fresh wort kits provide a convenient solution

Pressure release valves are a safety mechanism that will release pressure above a certain threshold. This prevents unwanted and potentially dangerous build-up of pressure. Their mechanism is simple: a main shaft with an O ring at the end which is held down by a spring. Depending on the spring force, the PRV will contain the desired pressure in the vessel, releasing any unwanted pressure by compressing the spring, and breaking the seal. Once the pressure in the vessel drops down low enough the spring force once again seals the vessel, preventing the escape of any further pressure. This is a bit of it of a simplistic overview, as we don’t want to make this too confusing.

Our Improved Design

By changing the ‘cap’ of the PRV, we have managed to increase the maximum gas release rate significantly! What does this mean? This means a safer

With he evolution of our P.E.T. pressure fermenter range there was also a need to improve the design and function of the spunding devices brewers use to control the pressure held and released in the fermenter tanks and also to control the pressure in their kegs when transferring from fermenter to keg.

When we originally introduced Fermentasaurus to the market in 2016 we only had one style of spunding valve that was manufactured from brass and cobbled together with a gauge using threaded brass connections with plumber’s tape between all the joins. There is a photo attached. This is the original design and utilised a poppet style adjustable valve tip.

The Brass upgrade of the original design was introduced in our NEW Design (photo attached) around the end 2018 beginning 2019. Our improved design was more sanitary and manufactured as one piece rather than multiple pieces. The valve tip was upgraded to have increments in PSI and BAR so that
