man, the preheating you'll have to do with this...
I was thinking about that too, but I have a stainless steel vacuum insulated french press, and I never preheat it.
the vacuum probably does a lot there.
The APSS says it's vacuum insulated too, but we'll have to see how well it works.
oh yeah so it does.
Ohhh that would make sence for the price. I was thinking of finding some steel pipe to cut down to size.
it has to be, otherwise the metal will cool the water down and coffee will taste like shit.
You guys still using water to make coffee? Water can drown at high amounts!
No. That doesn't change the fact that the metal has a higher specific heat capacity than plastic. The vacuum only makes it so that, once it's hot, it stays hot longer. That's not really useful here as it shouldn't be staying in the aeropress for that long, where it matters. It may actually make it worse, because you'll need thicker walls, and two of them, increasing the mass that you have to heat.
However, I think the "perfect" heat to brew with is slightly below boiling, so if you just use boiling water then the heat loss is probably fine. Still though, you're paying a premium for what is functionally a downgrade.
This is business. Cash in on simps who believe in myths.
