I take a 2 hour commute to school every day. My Stanley thermos, which was gifted to me by my very consumerist aunt, doesn’t keep my moka pot coffee hot for 2 hours.
Although it is a pretty good thermos it seems to be leaking a lot of heat from the metal section near the cap.
Is there any thermos that has every section of it isolated? Like, I shouldn’t even be able to tell if there is a hot liquid inside


Yeah they do sell hot water.
Currently planning to pack a french press. We’ll see how it goes, but I still want the thermos.
Since I use Hoffman’s french press technique the only thing I do is to dump coffee in water and wait anyways. So I might cut the filter from a french press and put it inside a thermos. I could then get it set up at home and just add water™
They SELL hot water? What a scam. Maybe bring an immersion heater?
It is pretty commonplace to sell hot water in my country?
Because bringing a heater with you is hard, the places which sell tea will also fill up your cup with hot water. For a fair price usually +5TL (~0.1 cent) more compared to bottled water of the same amount.
I can bring a heater and spend my university’s electricity for it but why would I so that when hot water is already very cheap.
edit: I just remembered my school’s water dispensers have a hot water tap. Students drain those very quickly though so I gotta go there right after my lecture ends
Bottled water is another scam though! Yes, use the hot water tap. But, doesn’t Hoffman’s French press method require near-boiling water? A hot water tap is typically maybe 60C at most.
Here’s the type of heater I was thinking of: https://www.ebay.com/itm/311442084287
That’s a US version (120V) but I’m sure they have 230V ones if you need that. Another idea is a camp stove.
incredibly inconvenient
Imagine sitting in the corner near the plug with your weird resistive heater waiting for the water to get hot
Also, things get pretty heavy when you have a 4 hour daily railway commute. There has been times when I didn’t take a bottle of water because it hurt my back
So I’ll just stick to carrying grounds and buying hot water. It costs practically nothing compared to my current habit of buying coffee which is a huge hole in my budget
