Mashing is not a totally smooth and predictable process so even with focus, experience, and care, we can be off more than we'd like. With that in mind, I thought I'd share my notes for the ways you can make corrections to realign your pre-boil gravity and.

Pre-boil gravity should be taken after all the grains are in the wort and the total pre-boil volume is met, in addition the sample should be cooled for an accurate reading. This way you have the ability to adjust the wort for proper gravity with either more water or some DME Also double-check the configured boil time and boil-off rate, since that will also be taken into consideration. Because of the diluted preboil wort, Beersmith also computes the pre-boil gravity, so you can check if you are on target. You expect the pre-boil gravity to be lower (around 70-80%) compared to your target OG Important factor in calculating you Original Gravity. If you don't know you system, a good number to start with might be 65-75%. And you can dial in your excact efficiency after a couple of brews. Mash Efficiency: The efficiency of your mash procedure, up to pre-boil, including sparging. Important factor in calculating your Pre-Boil Gravity The brew sheet always gives a pre boil gravity and a post boil gravity. I have tried but fail to see how the connection works out For example a 20 litre brew boiled for an hour has a pre boil OG of 1037 and an post boil OG of 1043 yet another has a pre boil Og of 1038 and a post boil Og of 1047. there is no linear method of trying to determine what you should end up with

(no secondary fermentation) I'm looking to improve my small boil/partial mash beers around this level. I feel the 1.040 SG mark I've been using generically via IanH's spreadsheet may actually be flawed on this level Dilution Calculator Use the following calculator to give the adjusted gravity after dilution. Unlike some tools, which allow you to input only your beer and the amount of water you are diluting your beer with, this calculator allows you to input one additional volume of liquid, as well as to specify its gravity of all three liquids Brew Log Type - 'Pre-Boil Gravity'. Measures: Partial Mash Recipes - Pre-Boil Efficiency is not reported. NOTE: The strike calculator assumes your tun will absorb heat (a few degrees will be absorbed by the mash tun, this varies widely by the type of mash tun)

With this calculator you can figure out the percentage of boil off to expect on your system. Pre-Boil Volume: The volume of liquid you originally started with in your kettle.

- This pre-boil wort is most likely going to be a lot hotter than the calibration temperature of the hydrometer. When you try to take a gravity reading the hydrometer will sink a lot further into the wort giving you an inaccurate reading
- You can also use it before you boil to make sure you're at the correct pre-boil gravity. This way you can make adjustments before the boil takes place. The Beer Recipator - I usually use the spreadsheet (recipe calculator) on this website when I'm making up a recipe

** Total volume of sparge water = Target pre-boil volume - volume of first runnings**. In our example, the target pre-boil volume may be 28.0 quarts (26.5 L) and the volume of first runnings is 6.3 quarts (6.0 L). Therefore the total volume of sparge water is 28.0 - 6.3 = 21.7 quarts (26.5 - 6.0 = 20.5 L) Specific gravity points (or GP) are the portion of the specific gravity reading to the right of the decimal point multiplied by 1000. For example, a specific gravity of 1.050 is 50 points. Using the pre-boil and post-boil volumes from the example above, with a pre-boil specific gravity of 1.036, the projected post-boil OG would be 1.049

Sparge Water Calculator. Use this sparge and strike water calculator to determine how much sparge water will be necessary to rinse your mash and get you to the proper pre-boil volume. Out of all our calculators this is hands down the most used. If you constantly brew different beers like us, this calculator is your best friend ** To calculate the OG, you need to determine volume of wort you will have at the end of the boil**. Divide the total number of gravity points by the number of gallons of wort. For the example above, lets assume this is a 6 gallon batch, so the wort will have 48.2 gravity points per gallon Re: pre-boil gravity Mon Sep 14, 2009 4:51 am Place your hydrometer in the fridge/freezer to bring it down to temp quicker then cross check your reading to your corrected reading in Beersmith It is the gravity of the boil (1.080) that is used in figuring the Utilization. As you will see in the next section, hop utilization decreases with increasing wort gravity. The higher concentration of sugars makes it more difficult for the isomerized alpha acids to dissolve. I use the initial boil gravity in my utilization calculation; others.

- Making this calculation at the start of the boil is a great way to dial in more accurate hop charges in the kettle to hit target IBU. Making the calculation at the end of boil helps you to work out how much liquor to dilute with so you hit your target OG. And remember, it's more difficult to take water out of wort than it is to put it in

For beers that use more grain (eg, high gravity beers), pre-boil efficiency, and subsequent efficiencies will be lower because of higher grain absorption. When brewing a high gravity beer make sure to pad in 5%, 10%, maybe even 20% efficiency loss depending on how strong your beer will be 2. And as another correction to me earlier post: BeerSmith in fact uses Pre boil vol minus trub&chiller loss as the input volume, and on top of that uses pre-boil gravity instead of average wort gravity. Which is pretty odd, although I guess the two errors cancel each other out to some extent In this video I talk about some tips to make sure you're hitting your pre-boil gravity every time without fail. Take chance out of your brewing technique and learn to master the lauter

The second is that your gravity is finishing at (or pretty close to) 1.010. These assumptions are necessary in this case to eliminate the inclusion of them into the calculations. By using a constant instead of factoring in potential changes in atmospheric pressure and temperature, you can bring your ABV calculation down to a few simple steps But, when it comes to the efficiency of the mash and lauter, we want to think in terms of the pre-boil gravity. The Extract Efficiency section and table gave us the typical malt yields that allows us to evaluate our mashing process

Pre-boil gravity of an American IPA Post boil. After the boil, a second measurement is taken. This one has a name - the OG, or Original Gravity. Through the boil, a reasonable volume of water evaporates, concentrating the sugars in your brew kettle. As the concentration of sugar increases, so does its gravity many apply, as the software calculates the liters of the pre-boil volume ?. We have always tried to explain the formula to our interlocutors. But since this question has become commonplace, we decided to write this article, where we explain how the pre-boil volume is calculated. The logic behind the formula is very simple: It [ In an attempt to dial my mashmaster mill some more I thought I was making the crush finer, and the following happened.

Add sparge water to mash, wait 20 minutes, then drain to kettle. Pre-boil gravity: _____ Pre-boil wort collected: ____ As wort gravity increases, solubility of oxygen decreases. It is very important to compensate for the decrease in solubility by oxygenating more aggressively. When brewing high gravity beers, it is best to oxygenate with pure oxygen through a scintered stone * The calculation is; pre boil volume x pre boil gravity = post boil volume x post boil gravity*. and to work out your post boil volume you take your evaporation rate from your pre boil volume - eg 28 L - 2.5 = 25.5 L after a 1 hour boil. So now you can put 25.5 into the equation

Pre-Boil (post-mash) - Knowing your gravity (and volume) going into the boil is important. It tells you how efficient your mash was. Just make sure your wort is very well stirred so that you get an accurate reading, especially if you are brewing with extrac You can correct your gravity at any time, but the best time to do so is before the boil with after the boil a close second. Pre-boil Gravity Correction . At this point typically your efficiency is off from what was calculated in your recipe. If you had poor efficiency your pre-boil gravity is lower than expected I could use a little advice with sparging... Ever since I got my new kettle, I'm been trying to sparge properly, as in my initial mash will have a water to grist ratio of 2:1, and then you sparge after your first runnings. But it seems like I'm not getting enough off my first runnings (~3 gallons), therefore my 2nd runnings just end up diluting it like crazy and I get low pre-boil gravities.

Now the valve is closed and a batch of sparge water is added to the grain and stirred in. That dilutes the wort that remained in the grains and once the stirring is complete another batch of wort, which is lower in gravity this time, is run off into the boil kettle.
