Caramelization only happens above 300*F. It is 230*F for fuctose, but there is little or no fructose in wort.

Both reactions are similar. They are both forms of non-enzymatic browning. The Maillard reaction is a reaction between an amino acid and sugar molecule. Caramelization is an oxidative reaction between two sugar molecules.

Sorry for the aside.
Thank you. I honestly couldnt remember the term used but knew that they were similar and that it did cause a browning (and assumed flavor difference with it). Glad you clarified that for me


It was actually a really good porter in the PM version, so i'm just hoping it turns out just as good.

I kept track of boil off rates and they were pretty inconsistent; too many variables I guess.
I've usually gone for 14%-ish and have been pretty close, but since it was colder out i tried and for 16% and it just didnt work out this time.

oh well.. brew and learn
