Mashing/Milling Problems?

[siwelwerd]

I have always batch sparged. Aren't tannin's extracted if the pH is low? More on the acid side?

dmtaylor is right, tannins are extracted when the pH is too high and temps are above 170ish (this is why some brewers acidify their sparge water, to keep the pH down). Since you batch sparge, is all of your wort tasting astringent, or is it just the last runnings? If it's all of it, then your problem is probably starting in the mash, and if it's just the last runnings, the problem is your sparge pH/temp.

Usually batch sparging is less prone to tannin extraction because you are not continuously diluting the mash.

There is always a slight cloudiness to the wort I don't ever remember seeing. I'm thinking the issue is stemming from adding all the salts to mash which is screwing up the pH. Before when I split it between MT and BK the two beers I did turned out great. Plus I throwing calcium carbonate in the mash tun which raises the pH. All in all it appears to a water newbie fuck up on my part. I'm gonna brew a pale ale this weekend going back to splitting the salts additions and see how it goes. Thanks for all the help!!

Well it happened again.... I ran off and got a big burst of cloudy wort right at the end. I have never had this issue before but it almost seems like the grain bed is not creating a good filter for running off. I am at a loss for this right now...
