Homebrewers - Whats in the fermenter?

[Salvelinus]

Used 5 gallons of syrup in a 10 gallon oatmeal stout batch today.

I call it syrup, but it came out of the arch of the system friends evaporate on. It is a little more watery than syrup and darker in color (SG 1.088). Has a strong flavor that should come through in the beer, and it was free. No way I'd dump 5 gallons of syrup in a beer at current prices! Hope it works out.
