Your grain absorption seems high. 0.75# victory. Enter your expected grain absorption rate here. There are purported pros and cons related to mash thickness, and some interesting research has been done on the subject. Total Grain Weight: The amount of recipe grains used in … 1.125 gallons sparge/mash-out water in 3 gallon pot - Should have minimal loss to grain absorption. From there, you can calculate your strike water as follows: Grain Absorption Rate x Total Grain Weight + Pre-Boil Volume = Strike Water Volume . “Grain Absorption” + “Finished Batch Size” + “Boil Off Rate” (60 min boil) + “Trub Loss” = Start Water For Grain Absorption, we have assumed 0.12 gallons of absorption per pound of grain. You will need a very large and durable fine mesh bag that can hold 20-30 pounds (or more) of hot wet grains. It will probably need some adjustment after you brew to dial it in to your particular process, boil off rate, grain absorption, and process losses. ezBIAB Calculator© With BIAB brewing all of the water and grain used in the mash goes into the kettle at the same time. You’re also going to need a copy of the all grain recipe you plan to brew, you’re brewing set-up’s boil-off rate per hour, grain temperature the day of the brew session, and your kettle’s interior diameter, assuming you don’t have a sight glass to measure your kettle’s water level. Assuming double crushing effects it? This is a simple BIAB calculator to calculate how much strike water you need to achieve your desired pre boil wort volume.. You will need roughly 26L in your urn to hit your target. The only other caution is that you might want to go to Options->Advanced and change the BIAB Grain Absorption to be the same as the normal grain absorption (0.96). See below for a discussion of grain milling, but for a standard grain crush an efficiency of 65% might be a better starting place. 10lbs of grain would equal .74 gallons of water lost to absorption. With grain absorption and boil off I would think I would be right around the one gallon mark. Mash volume calculations, Sparge amount, Mash thickness, boil off rate, trub loss, Grain absorption, Hop absorption etc. I do full volume mash, no sparge BIAB. You have to take into account that water lost from grain and hop absorption, boil-off, and the trub in the fermenter. Gal/Hr. Formula: w = ( l * g ) + ( r * ( x / 60 ) ) + b + t v = ( 0.08 * l ) + w p = b + t + ( ( r * 0.017 ) * x ) Estimated Gravity Readings. update: Real Grain Absorption should be about 1.41L/KG if … For Grain Absorption, we have assumed 0.12 gallons of absorption per pound of grain. Let’s say this recipe is calling for 12 lbs. I accordingly changed my constant in BeerSmith to 0.46238 and am now spot-on after some gentle squeezing of the bag while it sits in a colander. “Grain Absorption” 1.26 gal + “Finished Batch Size” 5.5 gal + “boil off rate” 1.25 gal (60 min boil) + “trub loss” 0.25 gal = 8.5 gallons hot liquor Step 2. If I start with a reasonable water volume (see spreadsheets below for estimating), I can hit my pre-boil volume every time. Input your desired Pre Boil Wort Volume and your recipe Grain Bill. I usually estimate at 1qt/lb loss. This is not the same as Apparent Absorption, but again, doesn't vary much, and is easy to calculate over a brew or two.

Custom sparge volumes, OR Enter Mash Thickness, OR Full Volume. Having brewed over 50 batches BIAB with an average extract efficiency of 79%, I can say with certainty that adding 33% more grain to pick up lost efficiency is unnecessary. Mash volume calculations, Sparge amount, Mash thickness, boil off rate, trub loss, Grain absorption, Hop absorption etc. This example is completely different to a brew in a bag mash. Boil-Off Rate. Mashout volume is difficult to calculate for BIAB so I calculate a boiling water mashout volume of 30% of the total mash water volume.. I can do the metric/English conversions needed to use The Calculator… That is the difference between the starting water and the resulting wort after the grain is removed. ... 2 thoughts on “ BIAB Calculator ” Bill says: October 14, 2014 at 2:21 am. Measured Grain Absorption. Grain Absorption Rate (gal./lbs.) Despite being mashed in a kettle that was wrapped with an insulative blanket my grandmother made, the BIAB batch precipitously dropped 6°F/4°C over the course of an hour long mash, while the no sparge mash only lost 1.5°F/0.9°C. Normal BIAB brewing retains a bit less water in the grain, and making this adjustment will make the BIAB mash profiles match the no sparge method exactly. Real Grain Absorption is generally about 1 to 1.2L/KG, depending on if you squeeze or not. In fact, BeerSmith’s standard sparge and BIAB methods have grain absorption rates set to 0.96 and 0.586 fluid ounces per ounce of grain, respectively, as it assumes some squeezing when utilizing the BIAB method. Also, no dead space calc. Revised Water / Grain Ratio: 23.6 fl oz / 51.04 oz = 0.4623824451 fl oz / oz. For BIAB, we recommend a very fine crush. Equipment. So I calculate dead space, absorption rate of about 1l/kg of grain, mash volume of 2.5l/kg of grain and boil off rate to figure out sparge amount. It turns out efficiency decreases roughly linearly with grain bill size. At this point, you can start to heat your water to the strike temperature. of grain and 7.75 gallons of strike water. Custom sparge volumes, OR Enter Mash Thickness, OR Full Volume. Some new things I haven’t seen elsewhere. If you plan your grain bills conservatively, you should easily hit your OG target. After mashing is complete, when you remove your grain bag, what’s left is the volume of wort that you will then boil. (Read more about squeezing the grain bag on page 46.) Add water absorption and you can double or even triple the weight. Water Volume Management in All Grain Brewing. I calculated the mash thickness by multiplying 1.5 quarts of strike water per pound of grain as (1.5 * 22) = 33 quarts or 8.25 gallons. How can I determine my grain absorption rate?

Sparging is irrelevant, because the grains retain the same amount of liquid regardless of how many times you run water through them. For your first few BIAB sessions, you may want to use the default values in the calculator for the following: Expected Fermentation Trub Loss (default=0.5 gal) Keep in mind that this could vary depending on your recipe, but should work for many recipes. So you need to calculate fermenter volume, grain absorption, evap loss, trub loss – and by the way, pellet hops absorb 7 oz per oz, so if you’re using a lot of hops assume that loss as well. In Australia another popular BIAB method is to use a 40 Liter electric hot water water boiling urn of the sort that you see in restaurants, church halls etc. Variations based upon grain are more appropriately sorted as barley vs wheat vs rye vs flaked grains, etc. The calculation is Grain bill x Grain Absorption (10.5 x.12). For that, I usually use BIAB Calculator. After grain absorption, i can usually get about ~6.5 total gallons out of it. I get about 0.1 gal/lb for BIAB when I do not do an extended gravity drain or squeeze, and 0.08 gal/lb when I do. Typically the grain, since you are draining it from the grain sack, retains less water and you have fewer losses to grain absorption as well. Single infusion mash at 156F for 60 min.

As you brew, take measurements and adjust for the future. This comes out to ~1 pint (0.125 gallons) / pound of grain. mash volume = pre-boil + absorption + grain volume = 28.5 + 8.3 + 3.26 = 40 l; Edit: added volume taken by grains. This can be done by having a very fine crush, good temperature control, and compressing liquid out of the grain bed. Although other variables did vary from mash to mash, the most significant change was adjusting the total water volume to compensate for grain absorption. (2.6 L/kg) and a grain bill calling for 10 lbs. Then I calculated how much water the grain would absorb by multiplying the grain absorption rate as (0.13 * 22) = 2.86 gallons which gave a total water volume of (8.25 + 2.86) = 11.11 gallons of water. That’s why BIAB is a popular Small Batch Brewing method (1-3 gallons). You have to take into account that water lost from grain and hop absorption, boil-off, and the trub in the fermenter. Let's figure out the starting water. So, if you are wanting to make 17L of beer with 5kg of grain, start with 17L, add 5 for grain absorption, 3 for evaporation and 1 for Gunk. In liters and kilograms, these numbers are roughly 0.5 liter per kilogram and 1 liter per kilogram. This number can vary based on the crush of the grain and several other factors. This is the amount of water soaked-up by the hops and hop bags. Grain Absorption: Some water will be lost due to absorption into your grains, which cannot easily be recovered; Mash Thickness: This is the measure of how much water (in quarts) is used per pound of grain. I was typically hitting my volumes spot on. It is a relatively newer way to homebrew beer and it goes against some of the traditional all grain brewing methods described above. Finished batch size is what you want in the fermenter, so usually you’ll aim for around 5.25 to 5.5 gallons to yield 5 gallons of finished beer. “Grain Absorption” + “Finished Batch Size” + “Boil Off Rate” (60 min boil) + “Trub Loss” = Start Water For Grain Absorption, we have assumed 0.12 gallons of absorption per pound of grain. Standard values include 0.125 gal/lb (1.04 L/KG) for a typical mashtun setup, 0.08 gal/lb (0.67 L/KG) for BIAB, and 0.06 gal/lb (0.5 L/KG) for a very hard BIAB squeeze. One of the most prevalent is .125 gallons of water per pound of grain. The BIAB water retention factor, 0.25 quart per pound of grain, is typically half that of a standard mash 0.5 quart per pound. We love BIAB for its simplicity and ability to make outstanding beers with minimal financial investment in equipment. Grain Absorption Rate. Gal/g.
