*Insert Private Pyle Voice Here* 350ml...FULL METAL JACKET!!! The normal aluminum base is now extended all the way up the sides as a shield to protect the silvered glass instead of the teflon netting. Additionally, I have now done the construction of this stein with aluminum spacers for the MAXIMUM METAL look (if you would like it with teflon spacers, as shown in Picture #5, please indicate that in your note). Brushed aluminum, stainless steel, and silvered glass for sciencey victory!
The interior volume is something close to traditional coffee mug or 12oz soda can. When not drinking beer or coffee, this is my preferred size for chilled cocktail administration. Also, it lets you look a bit less like a lush at Belgian ale houses as they're prone to serving in smaller sized vessels.
I've made this stein using a bench top dewar flask. I've found dewars still holding good vacuum after 30 years. This is, for all intents and purposes, the very best thermos you're ever going to find. It is quite common to fill these with liquid nitrogen, let it sit on the lab bench, and when you come back three days later there will still be liquid nitrogen in it.
Now imagine what it can do for beer.
Your last sip of beer will be as cold as your first. If you can survive a martini of this size, it will be frosty all the way down.
It will keep hot things hot as well as it keeps cold things cold. Your coffee will never need a "warm up" again, just refilling when you finish the last hot sip.
