Would it be better to make round kegs and then sell a plastic "sleeve" that fits over to make a square. Like a round peg in a square hole hahaha.

Then you only need to tool up for 1x keg and 1x sleeve? Dunno just a thought
Good idea-will run it past the team
 
Someone was asking after square-cornered kegs?

Attached here is a report of a taste test used to compare how the same beer tastes when stored long term in PET and metal kegs. As an initial trial with some rigour we were quite pleased with how this turned out. Next we plan to extend this to other types of beer and also to the use of bags within the kegs. With the Covid threat hopefully receding we will be looking for volunteers from our customer base to help with more expansive testing.

All I can say is
Ho, Ho, Ho (feck I want the sub/super script buttons back!)

Ho as is in never reject the null hypothesis.
Or in this case pretty meaningless BS results, not saying they aren't right, just that there is nothing to give one much confidence, no quality control, no external scrutiny or evaluation, sort of a Mythbusters level of science.
Wouldn't sell me one, nor stop me buying one, just really hate pseudoscience, or even people creating their own facts.

How are you supposed to conduct a taste test, which is inherently subjective, during a never before seen pandemic with lock downs?

Perhaps provide some constructive feedback to them so they can conduct a better test?
 
My bad sorry.

My post genuinely was a light hearted joke about a Xmas present....certainly didn't mean to start anything.

I reckon enough has been said about the taste test to allow people to make up their own mind about.

Let's leave it at that and not get into a shit fight that will derail the thread.

Not sure what we have done to deserve this sort of slur when what we are doing was conducted with some rigour in house and no claim was made that cannot be substantiated. One has to start somewhere does one not? Our next step will be to recruit a larger number of subjects and to involve a well know university brewing group so that we can put more scientific analysis behind this. No one created any facts. Perhaps you might be interested to be involved? This was done by someone who holds a masters degree in chemical engineering from Melbourne University and who has some award winning brews under his belt. He certainly does not deserve what you have thrown at him on this thread and its really disappointing to see this kind of post here still.
 
I found it an interesting read, and a reasonable first attempt at trying to evaluate any differences between their PET keg (not to be confused with other PET products) and the stainless keg.
Of interest would be an extended test with monthly tastings to ascertain at what point oxidation becomes a concern, or when the beer starts to "go off" irrespective of container.
In reality for a commercial environment 2 months is more than enough, it's more the home brew scene where you are likely to see extended times in keg.
Admittedly it's not "scientific" but the guys are in a warehouse not a laboratory, and are conducting a subjective evaluation with no mass spectrometer in sight, so good on them for at least having a go.
 
We thought people might be interested as we are making PET kegs available to the home Brew community soon. We kind of have already but next year once our second plant becomes operational they will be a viable alternative for folks to consider. For this we wanted to start finding out if people would be able to taste any difference. So our initial study we believe had value. It will move on to something more rigourous and use people outside of our staff. Maybe I am not very good at spotting the humour here but always up for a laugh that is based on something funny. So happy to be enlightened or better still why don't you get involved and help us with the future tests.
 
@MHB

As respected as you are on AHB for your great technical advice, posts like this and your earlier Ho Ho Ho one don't add anything constructive or of value.

As per my previous post, I think enoughs been said to let people consider the paper and make up their own mind.

I agree with @CEO Keg King ... we all love a laugh, but if that's the point of your posts, the humour isn't clear.

Please stop with the cryptic posts, anymore will be removed from this thread.

Not a criticism, as I think it is great to see more attempts at introducing scientific method into home brew, but is there any chance at seeing the complete results set from your experiment? Your experiment as written definitely isn't conclusive, but having access to the selection results of individuals may reveal something of interest.

I'd also recommend consulting with a Math post-grad from a local University that specialises in DoE for some advice on your paper (and any future ones). I'm definitely not an expert, but my (partially educated) knowledge of the field disagrees with your author's interpretation of the meaning of P value, and characterisation of null hypothesis.

Thanks for sharing.

If you like I can have you discuss it with the author of the report. He is currently engaged in putting ti together with a bit more to it. However what you say will be addressed once Monash Uni opens up again as we plan to have their Brewlab people do the next lot of testing with our assistance. For the moment it was heartening that differences if any were so negligible so as not to matter but we do plan to pursue this much more rigorously as soon as we can.
 
The report I released was not the final version and after the strange interchanges and moderator jumping in I decided to leave making it public here for the moments. Those who are interested to see it please just PM and I will be happy to send you a copy directly.
