A:Answer Sam,
There is not preset for beverage specifically--however since there is such a variance to how people take their drinks, it might be a bit presumptive to assume all drinks should be heated to the same temperature. I use the +30 seconds button to add half-minutes from zero, so I can figure out what works best for me at any given time. Turns out a re-heat of my favorite coffee mug takes 2:30 when it is room temp, but only takes 1 minute to reheat my favorite cold pizza.
Hope I've been helpful!
