![]() Finally the Lauter Tun Loss represents volume not recoverable in the mash tun. On some systems this volume can be large, and this setting will add more water to the mash tun to compensate. Next is the Mash Tun Addition which represents recoverable volume below the mash screen. In most cases you will either have a stainless steel pot (which is 0.12) or an aluminum pot (0.21). Similarly the Mash Tun Specific Heat is a factor based on the material used for your mash/boil pot. The Mash Tun Weight is the approximate weight of your mash tun and is used to calculate how much heat it absorbs from the water during the mash. Note that for BIAB you want a pot that is at least double your batch size to account for grains and extra water used in the mash. Enter your Mash Tun Volume which is the capacity of your boil/mash pot. Note this is overall system brewhouse efficiency and not mash efficiency as explained here. A good starting point is 68-72% if you don’t know what your efficiency for the overall system is. On the last page (step 3) you set your Brewhouse Efficiency. A detailed description of the whirlpool features are covered here. This is usually done with a whirlpool hop addition to maximize hop aroma. Finally at the bottom you can decide if you want to do a whirlpool/steep rest after the boil. It would only be higher if you were brewing commercial size batches. Near the bottom of the dialog you want to set your Large Batch Hop Utilization to 100% for home brew systems. Make sure the box Calculate Boil Vol Automatically is checked and that should give you your pre-boil volume. You will need to estimate your Boil Off rate, but 15% per hour (of the boil volume) is not unusual for a home brew system. On the next page set your Boil Time which is typically 60 to 90 minutes. Losses to trub/chiller can vary from a few quarts (liters) to a gallon or more depending on whether you bag your hops and what chillers system you use. Top up water (post boil) is typically zero for BIAB systems. Estimate your Fermenter Loss between fermentation and bottling which is usually a few quarts (liters). Name your equipment and define your Batch volume which is the volume into fermenter – typically around 5 gal (19 l) or 10 gal (38 l) for home brewers. I’ll walk you through each page in the equipment wizard. Create a new equipment profile using the Insert->Equipment Wizard selection in BeerSmith. The settings for BIAB equipment are not substantially different from any other setup. I’m not going to cover batch sparging or conventional sparging as these require a hot liquor tun and would use a traditional infusion mash profile. Using kettle top up water would be the same except you would need to set the Top Up Water for Kettle field in the equipment profile in BeerSmith, and also lower your Brewhouse Efficiency to account for the lower efficiency of the overall system. This would probably result in lower brewhouse efficiency as you are essentially diluting the wort from the mash with top up water.įor the purpose of this article I’m going to cover the traditional BIAB method in BeerSmith. You can, of course, mash a high gravity wort and then add additional kettle top up water after the mash which would still be a BIAB method. If you are separately heating water and sparging with it at the end of the mash, you are not doing a traditional BIAB method but instead performing something closer to a batch sparge. Traditionally this is done using a large mash volume that is larger than the boil volume needed for the batch so you can simply remove the grain bag and start boiling at the end of the mash. Brew in a bag refers to all grain beer brewing where the beer is mashed and boiled in a single large pot using a grain bag or stainless insert to contain the grains during the mash. ![]() Lets begin with a short discussion of what BIAB brewing is and is not. Profiles for many of these systems are available as add-ons under File->Add-on->Add in BeerSmith. Others such as the Blichmann BrewEasy use a two vessel (Kettle-RIMS) variant, but you can also use a BIAB mash profile to develop total water volumes for these systems. These include the Grainfather, Braumeister, Brew Boss variants, and Brewha BIAC. Brew in a bag methods and equipment are outlined here.Ī large number of single vessel “all in one” brew systems also use what is essentially a BIAB method. Brew in a bag offers simplicity in all grain brewing with less overall equipment expense and less cleanup. Follow week we take a look at how to set up and use BeerSmith with the “Brew in a Bag” (BIAB) home brewing method.
