Before setting up the Grainfather equipment, we will create a quick BeerSmith recipe and use the Grainfather Mash And Sparge Water Calculator to compare our numbers.Ĭreate a simple recipe using the new equipment and mash profile with a 10 lb grain bill.
The Grainfather app uses 0.32 gal/lb so if you glance at the numbers you may think they don't match.īy this point you should have completely setup BeerSmith. This value was taken directly from the Grainfather app, but watch out for the units. Within the Mash Step settings the Water/Grain Ratio should be 1.280 qt/lb. If your specific recipe has a grain weight higher or lower Beersmith will automatically adjust. This makes some of the other calculations easier. I used 10.00 lb to as the Grain Weight Basis for my mash profile. You can make multiple mash profiles and there are a lot of variables here but only two have an effect on consistency. The default Loss to Trub and Chiller in the Grainfather app is 0.53 gal. The amount of wort left behind in the Grainfather and the chiller. Maybe it's a bug? What I have done is set the value to 0% to make sure the calculators match, then set it to 4% just to account for this small loss. However, the Grainfather app, best I can tell, doesn't use this.
BeerSmith accounts for this by adding more water so you will hit your Batch Volume. The Grainfather app calls it Wort Shrinkage and the default value is also 4%. I have gone back and forth between 0.00% and 4.00%. Cooling ShrinkageĬooling Shrinkage is an interesting field. Same as the Boil Volume if you change your Boil Time you will want your Boil off as an hourly rate checked so it calculates automatically. For now I used the Boil Off value in the Grainfather Equipment profile 0.53 gal. I've measured mine anywhere between 0.5 - 1 gal/hr. Boil OffĪ lot of variables can influence your boil off rate. If you use something else your Boil Off volume may not match your Total Boil Off. Enable Calculate Boil Vol Automatically so you don't have to change the Boil Volume manually. Sometimes I change my Batch Volume or Boil Time depending on my recipe. I calculated my losses to be 0.33 gal and entered it in the Mash Deadspace Losses then I unchecked Adjust Mash Vol for Losses so the loss would be added to the sparge water. I use a kettle to heat my sparge water and it doesn't drain completely. I used the Recoverable Deadspace defined in the Grainfather App 0.92 gal. This is the volume of water not included in the mash below the false bottom. I used the Mash Tun Volume in the Grainfather App 7.93 gal. This is the maximum size of your mash tun. On the hot side, the Grainfather app doesn't account for Fermenter Loss and Bottling Volume. I want a 5.00 gal bottling volume and I normally lose 0.5 gal in the fermenter so my Batch Volume is 5.50 gal. The Grainfather default is just below at 0.0959 gal/lb, but the Grainfather Mash And Sparge Water Calculator default is 0.1 gal/lb.Ĭreate a new Equipment profile for the Grainfather. The BeerSmith default is near the middle of this range at 0.12 gal/lb. Most sources suggest a ratio of 0.1 - 0.2 gal/lb.
This constant can vary depending on a number of factors. The Grainfather uses gal/lb so these numbers shouldn't match between the two applications. Watch the units and convert if when needed. I used the default value in BeerSmith 0.9600 fl oz/oz of grain. We are only interesting in the Grain Absorption value. Go to Advanced Options in the BeerSmith Preferences Menu. If a BeerSmith setting isn't called out, it's not believed to have an influence on the consistency. This document is intended to get the same results between the two applications. Note: The Grainfather website can also be used, but some fields are in a different sections and some default values vary between the website and the app. Grainfather Community 4.0.19 for iPhone.In the Grainfather App we will be in three sections.Īt this time I'm using the following versions. In BeerSmith we will primarily be concerned with three sections. The goal is to share my profile and explain how the settings are linked between the two applications so you can adjust them to your liking. After some adjustments in both pieces of software, I have an equipment profile that matches. I downloaded BeerSmith's Grainfather Equipment Add-on and found several online variations of the Grainfather Equipment but none matched the current Grainfather App. I have been using BeerSmith to design recipes for my brewing equipment but I recently switched to a Grainfather.
