What's the best way to make iced coffee?

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.
