Looks like our opposition is still desperate to hang shit on us. Take a look at this:
If you want to do an experiment with the Fermenter King Jr you can put a Light Lager or Pilsner or some other light flavoured beer into this type of keg then see what it tastes like after 3-6 months. The beer will be oxidised and taste a bit like cardboard. It's ok if you are fermenting but then again the opening size at the top is a bit small for a fermenter and hard to clean for this reason. So it's really designed like a keg but then sold as a fermenter because the oxygen barrier is not good enough for a keg.
We are going to release an 8L keg that uses a multi-layer preform and as a result has very good oxygen transmission rate but this probably will not be until the end of the year. If this product is successful then we will also make a 20L design that will be similar in size and shape to the corny kegs at the moment. The development cycle on these products is quite long because the multi-layer walls are far more difficult to make.”
Yes absolutely now that second hand kegs are pretty much dried up all over the world we have been putting significant effort into making plastic kegs so we have a lower cost way to get into home brewing. With that said kegs above all else need to protect the beverage against oxygen. Many people have this idea that PET is impermeable but in actual fact it's not. Oxygen can pass through PET at a slow rate. As a result I would never put beer into PET for an extended period as the gas transmission rate is not suitable to be stored in PET for more than 1-2 months. In order for kegs to be acceptable for long term storage standard PET grades are not able to do the job. Really what you have to do is use a multi-layer preform. This involves other plastics such as EVOH and other newer polymers that are sandwiched in between the PET layers. When this is done the plastic keg can have barrier properties that are comparable to a stainless steel keg.“Wolff said:
Hey @KegLand-com-au first of all thanks for keeping us all occupied here in Vic!
Apologies if it's been asked before, but have you ever considered creating a PET Corny Keg (or at least a similar vessel with the same outer dimensions?).
Something like Keg King's 'Fermenter King Jr' but in 9.5L/19L and in the same footprint of a ball lock corny keg.
I'd definitely swap out my stainless kegs to be able to see the liquid volume for transfers and keeping track of what's left.
