That’s not true. The plunger is not impermeable and the grounds are still wet.

It's possible that over extraction could occur quickly, so the use of a thermal carafe to maintain the coffee's temperature would only be beneficial if you transfer the pressed coffee into it. This means that the statement about holding in the french press for a "long time" does not align with the importance of preserving the quality of the coffee. Imho.

That could make your coffee taste less than ideal, if you are storing the brewed coffee in there. French press needs to come off the grounds after the brew or it will over extract. I suppose if you mean it keeps it hotter during the brewing time, you’re right about that. But then if it is hotter in the cafetière it will brew slightly faster too.

Appreciate the comment, but no. I knew that, and it still never got tight enough for me.

I switched to a ratchet belt system and never looked back. No training necessary lol

Meh. I gave up on my grip6 belt. It’s nice and light, but I could never get it tight enough because of the gimmick. Good idea, it just didn’t work for me.
