I’m a big fan of the Fellow Carter Move mugs. They definitely keep coffee hot (or cold) for quite some time. I actually have to cool off my freshly brewed coffee before I put it in the mug if I want to drink it in without waiting a long time. There are a few lid options, but I’ve found that the standard lid and slide lid keep temperature the best. There’s also several sizes available, though the 20oz is listed as a cold mug, it’ll work with the hot lids.

I realize I sound like a shill for the brand, but I just really like the mugs haha.

Looks like that is a home brew cap of some sort.

I like to use a French press for my iced coffee so that it has more body and a thicker mouthfeel. I use James Hoffmann’s French press method, but use a 1:14 ratio of coffee to water. The water is split 70:30 water to ice. After the brew is done, I just pour the “concentrate” over the ice to cool it, then pour over fresh ice in a glass.

My standard brew ends up being 32g coffee, 315g water, and 135g ice.

Currently using wezterm, mostly because it supports font ligatures and alacritty doesn’t (I really like the fancy symbols haha). I do use the window management in wezterm, but I’d go back to tmux if alacritty implements ligatures.
