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.

I know that's frustrating and a bit terrifying to see all that work disappear.

As long as you haven't opened BeerSmith more than 5 times, you can recover from autobackup.

Go to File > Recover from Autobackup > Choose the date . Click "recover from backup selected" in the lower left of the window. Click "yes" on the "are you sure?" popup.

I went into my system the other day and most of my recipes have disappeared.  I can see some in the archive and even where they were stored but the folders are gone.  How can I recover them?

I transfer to bottle, but I wouldn't do it for secondary. When bottling using old school methods, you extend tubing into the very bottom of the bottling bucket trying as much as possible not to make any splashes. As with everything else, you sanitize the living hell out of everything that comes in contact with that beer too.

BeerSmith 2 Questions / Re: Volume calculation and temperature correction
« Last post by brewfun on May 30, 2022, 06:56:20 AM »
so all these volumes should be at the same temperature so a tool to correct the volume based on live temperatures would address this. 

The real issue is measuring in volume instead of weight. If BeerSmith used weight as the base measurement, then converted to volume for ease of use, there wouldn't be a gravity calculation error that's exactly equal to the expansion factor. However, in real world brewing, this becomes moot when using BHE because the error gets corrected.

A pint in 5 gallons will make a different in gravity and extraction.

Again, BHE is all about correcting for that.

I actually think this correction would be important as Beersmith records the volumes at various steps, which I use to dial in my equipment.  The water calculator uses this data to predict how much water to start and compares the volumes by simple addition or subtraction so all these volumes should be at the same temperature so a tool to correct the volume based on live temperatures would address this.  A pint in 5 gallons will make a different in gravity and extraction.

How to accomplish a closed transfer also depends a lot on the equipment being used. Without knowing what you have makes it hard to suggest a method.

Here is a diagram of a basic closed transfer system. Whatever vessels you use it is gas into #1/beer out of #1---> beer into #2/gas out of #2. The first and last ones are most important. You only want a small amount of pressure going into #1 and you want to relieve the pressure out of #2.

Best way is not to transfer to secondary. Unless you're bulk aging a beer there's seldom any reason for secondary and any perceived benefit is outweighed by exposure to oxygen and the possibility of contamination. Most experienced homebrewers quit using secondaries several years back.

A closed transfer using CO2 to push from one vessel to the next is pretty standard. However I avoid using a secondary step whenever possible. Haven't used one in about 12 years actually.

Does anyone have an excellent set up that will greatly reduce the amount of influential oxygen when transferring from primary to secondary?
