Building a mill for grinding grain barley malt is a bit like pork, do not throw anything under cons

In this blog, that comes from my huge passion pmkeys self service for beer, will note data, images and comments on my recipes homebrewing. pmkeys self service I will also include tips and techniques related to everything that revolves around the world dell'homebrewer.
Today I am going to explain how to make corrections density during pmkeys self service mashing. How many of you happened to be less beer than initially established? The causes normally be sought in factors such as a poor extraction of sugars from the grains (bad grinding) or by improper rinsing the spent grains (spreads). Few people know that it is possible to "readjust" a recipe during processing, just as the wort is in the process of boiling. In fact, knowing density and gallons pre-boil pmkeys self service is possible to estimate how many gallons will be at the end of the fermenter. Let's see how. The first thing to know is to go to measure the total density throughout the production and use it as a guide to correct the wort to the desired density. One thing to keep in mind is the concept of total density which is the product of the volume must be multiplied by its density in OJ. An important feature is that the total density does not change when you boil or dilute the juice. Therefore, to measure the total density, it is necessary to measure both the density and the volume of its wort and this will have to do so when the wort is boiling phase. For the density just take a little bit of juice and use a hydrometer (pay attention to the temperature value at the time of measurement because the heat falsifies the real value of the density, there are correction tables which help us to calculate pmkeys self service the correct value of the density temperature changes). For the measurement of the wort must possess a calibrated pot, or, for those like me who does not have one, you can use a wooden spoon calibrated. We use an example of an all-grain to explain how you can use the values of the total density pmkeys self service in our favor. Having measured the density and volume of the wort in the pot and knowing how many liters of beer you really want to produce, you may know what is the density of the wort boiling at the end: [OJ (start) x LT (start)] / LT (end ) = OJ (end) Let's say you want to produce 24 liters of beer with an OG to 1.068. Multiplying these figures pmkeys self service (24 x 68) it turns out that you need a total density equal to 1632 OJ. When you reach the boiling phase we perform our measurements and discover pmkeys self service that, by multiplying the density and liter pot, the total density is 1480 OJ. To center our goal, therefore, it takes 152 OJ. To obtain OJ 152 we can rely on, for example, the addition of dry, liquid, sugar or honey. But in that weight add these products to get the 152 OJ missing? To find the amount pmkeys self service of weight of dry extract that is used (for example), you must perform the following formula: extract (kg) = (total density to be achieved - density total pre-boil) / (value extracted / 10) or extract ( kg) = (1632GU - 1480GU) / (38/10) = 0.4 Kg The value 38 is obtained from the table below
1025-1029
1.030 In conclusion, in the process of boiling should be added to 400 grams of dry extract to get our total density expected at the end of the boil. For more info, I highly recommend purchasing the manual Designing Great Beers by Ray Daniels. I hope to be of help, the next ... beer
