I want to brew this next weekend so I went ahead and tried to make this syrup with the LD Carlson Yeast Nutrient. I followed the OP instructions exactly. I live at 6288 feet above sea level so I used the high altatude instructions and cooked too 240 degrees. I got syrup but no color. I ended up cooking to 250 degrees and still just a slight bit of color. I cooled the syrup and it basically hardened to a chewy consistancy. It was not liquid any longer but thick. Im going to buy the DAP and try again as that is the only thing that I can think of that changed my attempt.
