It may actually make an excellent batch, who knows? Yeast is yeast. It will ferment any available sugar without disdain. All of our current beer styles were probably the result of just such a mistake (opportunity?). Steam beer was made because they had lager yeast but no way to refrigerate it to cool the wort and make true lager. It is now considered to be the quintessential American contribution to world brewing.
Give the yeast a chance, man!!
