I've not put warm beverages in the style bottle you are describing. I have used room temperature water in a room temperature bottle for cold weather riding (below 32 degrees). This delayed the water freezing. It got pretty darn cold after the half hour mark, but didn't freeze within an hour or so ride. To prevent my bottles from freezing, and this would also provide warm/hot tea/coffee, I use oversized bottle holders and Yeti tumblers. That's more likely to achieve what you're looking for.
