Introductions / Willamette Valley brewer
« Last post by punomatic on June 08, 2022, 04:35:39 PM »
Hi, everyone,

I'm new to the forum, but I've been brewing off and on since the early 90s. I recently purchased Beersmith 3 to replace my open source Brew Target app. Then I discovered this forum. I look forward to learning from y'all and will chime in when I have something to offer.

Hi,
  The OG is based primarily on the brewhouse efficiency, as well as the volumes.  Changing boil volumes will change the volumes but not the brewhouse efficiency which is a gross number that reflects all losses in the system.  So that may explain the slightly higher OG.

Thanks for the replies. I'll think on this. But I'm not sure any of this answered my question.

What made the recipes disappear? Is this a cause for concern for all of us?

The temperature may be the difference. The pre-boil gravity is at boiling temperature, while the post-boil gravity and OG are at room temperature. There is a 4% difference based on the thermal expansion/shrinkage. If you take 1.070 and multiply by 1.04 you get 1.073, exactly the number you are looking for.

Once you've used accurate measurements for a few batches, adjust equipment profile values as needed and then adjust brewhouse efficiency.

This is important right here. You may have done the proper volume and weight measurements to set up an equipment profile but it is not complete until you make adjustments along the way. Take accurate measurements of every brew day and use these to tweak your initial profile until you have it dialed in.

You're comparing apples to oranges. You need to compare accurate pre and post boil gravity and volume measurements. Using a prediction for pre boil and actual OG post boil doesn't work, especially if you're not accurately measuring volume too. Once you've used accurate measurements for a few batches, adjust equipment profile values as needed and then adjust brewhouse efficiency.

BeerSmith 3 Support / Gravity calculations in BS3
« Last post by thebeershack on June 03, 2022, 09:02:00 AM »
I'm an experienced brewer, but a BS3 noob, having a hard time understanding BS3's gravity calculation, as it seems to consistently estimate a higher post-boil gravity than the standard calculation would predict. I do have my equipment profile properly set, including the boil-off rate. Let's take a look at today's batch: BS3 predicts 1.059 post-mash gravity with 9.6 gallons going into the kettle. My boil-off rate is 1.5 gallons/hour, and today is a 1 hr boil.
so: 59x9.6=566.4 points going into the kettle. A post-boil volume is 8.1 gallons, so the estimated post-boil gravity: 566.4/8.1=70, or 1.070 OG. Yet BS3 is giving me three more points with an estimated post-boil gravity of 1.073. This gravity would be produced by a 7.75gallon final volume, or a 1.85 gallon boil-off rate. I do have the "Use boil-off as hourly rate" box checked. What else is BS3 factoring in to produce this discrepancy? I want to account for this (small) difference during recipe creation.
