Hey guys, I am fairly new to brewing, I have like 10 extract brews under my belt. Anyway, my first few batches were box kits. Since I keg, I have never used the priming sugar that came with them. So with my newest IPA recipe I decided to use 1lb the last 15 mins of my boil. I killed the flame, added and dissolved the sugar, then brought it back to a boil. When I took my OG, it was way lower than Brewtoad predicted. 1.061 predicted vs. 1.052 actual. And yes, I do adjust my OG readings based on temp, hydrometer etc. I researched it, and my OG is actually what it would be without the priming sugar. Everything I have read says that priming sugar is corn sugar. Is this wrong? Btw, all of the kits were from Brewcraft. Just curious if anyone has ever had this issue, or if this will have a negative affect on my beer when I keg it.
