When I add sugar to get the SG up after I made the invert sugar do I need to "cook" it again or can I just put it in the fermenter and mix until dissolved?
I made inverted sugar by boiling 16 cups sugar with some lemon juice for 1/2 hour. When I added it to lemon juice the sg was only 1.05 so I mixed sugar in some must and added it to get sg to 1.080. I didn't boil the sugar must mix for 1/2 like you do to make inverted sugar. I only heated it until the sugar was disolved then dumped it in.
