Unless you are mashing, the pH is less important. I assume the same would be true of grain steeping, so I always add my extract before steeping to keep the pH low, and avoid excessive tannin extraction. Anyone with more legitimate chemistry background care to comment? Mashing requires a balanced pH if you do a search you will find an article on this of around 5. However since you are not extracting sugars from steeped grains this is less of a concern when steeping.
However the pH is a much less important factor in this process than with mashing. Keep up the great work! You know, many people are searching around for this information, you can aid them greatly. You can mash it if you have the equipment and knowledge, but that would require some pale malt to provide enzymes for the mash.
I am apparently in a twilight zone between extract and partial mash brewing. My measured OG was 1. I am trying to figure out why I was so far off.
Was the closeness of partial mash estimated OG and actual OG a coincidence? Follow BeerSmith Steeped grains enhance the flavor and color of home brewed beer. Don't make another bad batch of beer!

Im obliged for the blog. But you need to be aware that you can introduce off-flavors into your beer by steeping grains incorrectly.
Specifically, you can get an astringent flavor, which can vary from a slightly bitter flavor to a strong sour flavor akin to sucking on a tea bag. The astringency comes from tannins, which are a polyphenol extracted from grain husks.
Since all beers are made with grains, some tannins exist in every beer. In most cases, the tannins remain below the flavor threshold. However, you can get an excess of tannins by steeping specialty grains at too high a temperature or with too much water.
Going higher will leach tannins into your wort. This will keep the crushed husks contained and out of the boil. If husks are boiled, they leach tannins. So, at some point all hobbyists make the slow transition through steeping and mini- or partial mashing.
Some stop here, which is perfectly fine. Many award winning brews have been made with partial extract. Others will continue their journey into the world of all-grain brewing. This will be especially pertinent information for those homebrewers just starting the transition to using specialty grain and maybe a little base malt in their brewing.
Steeping is the process of soaking crushed specialty grains in hot water to extract color and some flavor compounds from the grain. Steeping is the logical first step into brewing with grain. It opens up new depth of flavor and color to be plumbed.
This is better than using only extract, but it is still limiting. Not all grains are suited to steeping. All grains can be put into a mash, not all grains can be steeped.
Some grains have enzymes that must be activated and put to work to make the sugars in the grain available. A mini-mash is soaking grains in hot water at a particular temperature range to activate these enzymes, which in turn drive the conversion of grain starches into usable sugars.
The malting process decides which grains will work in a steep. If the grain has its starches converted to sugar during the malting process they can be used in steeping. These are most often the specialty malts.
Some are stewed during the malting process Crystal malts and those that are kilned at higher temperatures for longer periods of time also have been converted in most cases.
Any Roasted Grain chocolate, black, roasted, ect. Crisp Chocolate Steeping Procedure The steps for steeping are very simple. The precise temperature of the water is not overly critical. You are only extracting color and sugars already present in the grain and not trying to activate a living enzyme that needs a specific type of environment in which to do its work.
More water will help extract more of the color and flavor, but it will also pull more of the tannins out. Also, the pH is likely to stay closer to the optimal pH of 5. A good volume is 3 — 4 quarts of water per pound of grain. The grains must be crushed, otherwise you will extract very little from them. Crushed meaning cracked, not pulverized into a powder. Also try to use crushed grain as soon as possible because it will begin to oxidize once cracked.
Once cracked, mix your specialty grains together and put them in a grain bag of some sort. But be sure your bag is not touching the bottom of the pot if you are heating the water, because it is possible to burn a hole in the bag.
