@jeremy_pm @jeroen @fesshole in the South, we actually drink a ton of tea, but it's brewed very strong in large batches and served over ice.
People usually get this out at restaurants or from a fast food drive through. When we do make it at home, typically it makes more sense to just heat water in a pot and drop the bags in there to steep.
Another tradition is sun tea, which again requires a large vessel for a batch brew.
