Late Sugar Addition Affects Pre-Boil Gravity
« on: June 17, 2015, 01:52:12 PM »
Adding 2 lbs of candi syrup as a :15 late addition changed the pre-boil gravity.  Shouldn't this only affect OG?

What's the fix for this, other than hoping to remember to back out and add back in the late addition when checking gravity?

Thanks

This is a well known bug with lots of other threads on the subject. It's apparently on the update list.

BeerSmith has a fairly simple approach to all fermentables: The are summed together to pre boil and pre fermentation numbers. So, regardless of when they're added, sugars are all part of wort production. That's inconvenient for secondary sugar additions late into fermentation, too.

The easiest workaround is to zero out the sugar while making wort, then add it back for the boil.
