![]() ![]() ![]() Is this accurate and if so, is this new Brewhouse Efficiency what I should plug in for future batches? It ends with him doing a guess/check technique with his Equipment Profile Brewhouse Efficiency until his Est Mash Eff and Measured Mash Eff from the Mash tab were close in value. This video for example, walks through a mock brew day and how to find your overall total efficiency. Be sure to sign up for my newsletter or my podcast (also on itunes…and youtube…and streaming radio station) for more great tips on homebrewing.Does anybody really know how to use and adjust this thing? I feel like I've seen so many different articles and videos of people offering their own thoughts, but nothing too concrete. You can grab a trial version of BeerSmith from. Thanks for joining me on the BeerSmith Home Brewing Blog. Those are some suggestions for managing your mash and avoiding astringency. Some people do use higher temperature sparge additions, but only to raise the temperature of the mash as a whole during the initial phase of the sparge. At this temperature you get a good balance of viscosity and solubility for the wort. ![]() The recommended temperature for sparging is 170 F (77 C). Sparging at a moderately temperature has some benefits as it improves the flow of wort through the grain bed. Sparging at excessively high temperatures can also result in astringency in the finished beer. Some brewers with a pH meter also have the option of monitoring the pH of the runnings and stopping when the pH rises above 6.0. Obviously that number would be higher or lower if brewing a very high gravity or low gravity beer. The most common method to avoid oversparging is to monitor the gravity of the runnings and stop sparging when the gravity falls below 1.008 for an average strength beer. In particular pH levels above 6.0 and running gravity readings below roughly 20% of the target gravity are associated with tannin extraction. So as the pH of the mash runnings go up and gravity of the runnings go down we again run the risk of extracting tannins near the end of the sparge. Similarly as we extract more sugars from the mash the gravity of the runnings will go down. So if we look at the case where we’re mashing in the proper pH range, it is pretty easy to see that as we run more water through the grain bed during the sparge, the pH of the runnings will go up over time. Water tends to drive the pH of the mash higher, and grains (particularly dark grains) will lower the mash pH. This is primarily a problem in lighter colored beers as dark grains are acidic and tend to drive the mash pH down. You can use a variety of methods to measure and adjust your mash pH to keep it in the desired range. In particular, pH levels above 6.0 during the sparge are associated with tannin extraction. If the mash pH is too high, more tannins will be extracted into your beer. Your mash pH should be in the 5.2-5.5 range after mixing in the grains. A dual roller mill will crush the grains but still leave large pieces of husk intact.Īnother risk factor is simply mashing with the pH too high. That’s why I recommend using a dual roller mill. A proper crush will finely crush the grain core but leave large pieces of the husk intact. Usually this is the result of using a “flour mill” or corona type mill or simply setting the mill gap to be too narrow. In particular if you crush the husks to a fine powder it can result in excessive tannin extraction. One potential cause of astringency is crushing your grains too fine. During the mash and sparge you can extract excessive tannins which will affect the flavor of your beer. Tannins are a phenolic category of polyphenols that naturally occur in grain husks. AstringencyĪstringency in the finished beer is usually the result of excess tannins extracted from the grains during the sparge process. This week I take a look at astringency, oversparging and sparging your grains too hot. Follow which is a dry, vinegar like off-flavor in your beer, can be caused by oversparging or sparging your grains too hot while brewing. ![]()
