What is 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 temperature is key to achieving the best quality beer possible and in order to do so, you want to take temperature readings straight from inside the liquid.

Does Apollo come in stainless steel?

Yes! We have called it Apollo Titan and it's current the cheapest stainless steel fermenter on the market that does pressure fermenting of up to 35psi. Titan has the same conical shape as our trademark Apollos with 3 additional 1.5" tri-clover openings for you to play with. Fittings you might be interested in, include a sightglass, a 90 degree elbow and of course a sanitary butterfly valve.

Conical Fermenter

What does conical mean and why is it different from the other styles of fermenters?

Just about any vessel can be a fermenter if you ferment something in it, but you’ll notice most commercial breweries have pronounced conical shapes at the base of their fermenting vessels. This is because after a few thousand years of commercial brewing it was noted that removing the yeast bed from underneath the fermenting beer helps to keep flavours cleaner, store better and reduce the chance of yeast autolysis (a.k.a Band-aid/medicinal flavours) in your beer. The cone at the base of your Apollo fermenter helps to concentrate the flocculated (dropped out) yeast and minimise the contact the yeast bed has with the beverage. In a unitank variety conical fermenter, the dropped yeast can be removed and harvested for repitching. In a closed bottom fermenter, the minimal yeast bed to liquid contact helps reduce the chance for the yeast bed to impart flavours into the beverage.

Are conical fermenters better?

For Beer, absolutely. The right shape for fermenting beer is conical. A 60 degree angle is optimal just like we put on our Apollo fermenters. A wider angle and the yeast won’t slide into the cone. Conical makes yeast removal easier and liquid to yeast bed contact smaller.

Apollos Trips and Tricks

Why a 30L or 60L fermenter?

An average brew size is 19L so that it fits perfectly in a regular corny keg or 20L if you use one of  our PET corny ball lock keg so a 30L fermenter will provide ample head space during fermentation and contain your nectar safely. We do recommend that you  use a spunding valve to increase both the quality of your fermentation and the safety of your equipment.
