Measured pre-boil gravity versus measured OG
« on: November 05, 2016, 06:41:38 AM »
Hi there,

In the design tab, under select fields, there are two fields, measured pre-boil gravity and measured OG.
Can anyone explain what the difference is between these two fields please?

Additionally, under volumes, is there a way to change the post boil volume field to reflect what the actual post boil volume is?

There are now three gravity measurement points.

Post Mash Gravity is the expected gravity just from the mash.

Pre-Boil Gravity is what you'd expect to measure in the kettle after adding any kettle sugars, prior to boiling. If there are no kettle sugars added, then this should read the same as Post MAsh Gravity.

Original Gravity (OG) is what's expected after the boil and after any water additions found in your equipment profile.

In all cases, BeerSmith makes an estimate based on the parameters you've set in your equipment and mash profiles. The Measured fields are for your actual results during the brew session. BeerSmith has some numbers in there already, simply as place holders. They are not related to the estimated numbers, even if they appear to be close.
