Hi!
I just accepted your invitation.
Any chance to see the product?
I understand that you like the styles of those three architects but would be happy to see the keg itself.
It may inspire for a really corresponding logo.
Thanks,
Slobodan

Thank you for the insight. Unfortunately, I would prefer to keep the product hidden until it is finally launched. Alas, it is a none-too-impressive looking product. It is a beer keg, made of plastic, much like this one:

While the outside may seem unremarkable, the inner workings are the true innovation.

The logo would be printed onto the keg for showcasing purposes, and proper company branding identity, but the brewery's branding would occupy much of the rest of the keg label. That is why I would insist in an easily identifiable and iconic logo, so as to set the product apart visually, in addition to its material composition.

I hope this helps,
Chris Frank

Yes, it certainly does help.
Thank you,
Slobodan

Here are a few designs I love:
