@craigmaloney : according to my wife (I don't drink coffee)) , cold-brewed coffee has less of the acid bite because, other than being roasted, the beans are not 'cooked.'
There are also convenience issues. When I owned a gelato shop, we used cold-brew to make a coffee concentrate that we kept in the fridge (it keeps for weeksl). When a customer ordered a cup, we'd pour out a 2 oz. shot of the concentrate and added hot water. A lot of customers really liked it because it tasted "smooth."
