Hi - This is my first post on Beersmith. I recently moved from extract brewing (~10 batches) to BIAB and also started using Beersmith for this batch. I have a question about the Adjust Gravity tool in Beersmith.
I was brewing a 5 gallon batch of Petite Saison with the following grain bill:
- 7lbs of Pilsner (2 row)
- 3.5lbs of Vienna Malt
- 0.75 of Torrified Wheat
After a 75 minute mash at 152 and a 10 minute mash out at 168, I ended up with an OG of only 1.020 instead of my estimated 1.041. I had a feeling this might happen, so I already had some DME on hand. I popped the calculations into Beersmith's Adjust Gravity tool:
- 1.020 for the Original Gravity (my actual pre-boil gravity)
- 8gal for the volume (my actual pre-boil volume)
- target gravity of 1.041 (my target pre-boil gravity)
It calculated 3.64lbs of DME to add. Well, I only had a 3lb bag on hand, so I dumped it all in at the beginning of the 90 minute boil. During the boil, the only other thing I did was add a total of 3oz of hops.
After the boil, I used the immersion chiller, followed by O2 in the carboy. I took my OG reading and was shocked to see 1.055. I had expected an OG of 1.048 if I had hit my pre-boil gravity.
What did I do wrong when calculating the amount of DME to add? Or did I add the DME too early in the boil? Are there any other variables I need to consider?
Thanks for the help!
