What happened was to crank up the beer an extra 2-3% ABV, you have to not only make a batch with a much higher grain to water content, this will get it to 7-7.5%, but you also include a quantity of sugar with the boil kettle. In this case, about 20 lbs of a Belgian Candy Sugar.
In the big picture, no big deal, just a little extra clean up today and next time will simply make a smaller batch. The beer should be ready in 3-4 weeks, or around mid-July timeframe.
