Low PH and Dull flavor with Brown?
« on: July 26, 2014, 11:09:15 PM »
Do ya think a low mash PH of 5.2 to 5.3 will result in more of a "dull" characteristic in the finished beer? An American Brown ale

Not dull so much in this beer. In roastier beers (brown, porter, stout), a lower pH can emphasize the very roasty, sometimes acrid, aspects of the roasted malts. Obviously there is a lower % of roasted malt in a brown as opposed to porter and stout. Just try it and see what you think. I target 5.5 as my pH in Bru'nWater for these styles, which I feel gives you a softer, more balanced roastiness. You'll have to post your final results - good luck !

I ask because i am frustrated because i attempted this recipe this AM with shooting for a 5.6PH and ended up with 5.0 at that so i dumped it and re did the water  and cont to have a lower PH than i desire. I have never had this issue before my water must have changed because i have quit a bit of bicarb.

How do you check your pH, out of curiosity ?  Paper strips are worthless IMO - the colorphast strips are better, but read low.

A Milwaukee 101 meter at room temp 77F, calibrated every other batch with a 2 point solution. My solution is a year old and i have been wondering if i should replace it.  I use brunwater and am most of the time within a tenth of a point of what it predicts. i will re post with tasting results

i will hope that with only 2% truly roasty/Cholo malt that it will not be as acrid

How about your water?  I use RO water from a grocery store machine and build, but I only recently bought a TDS meter (~ $20) off Amazon. Stores can be pretty unreliable about the integrity of the membrane in their machine and "RO" water can sometimes be not so much so. I bring the (small) meter to the store and check the water before I buy any each time. It's a cheap easy way to GUARANTEE the quality of your water. Definitely worth $$.

I do the same. Great idea on the TDS meter never even thought of that. Being my HC03 is always so high i always cut my water with RO. I normally dont for my darker beers and have always been in the range/5.5ish however i have never made this recipe with this grain bill. just started my boil with a 5.4 PH and am using WLP007 and i know this yeast does not buffer that well so i am predicting that i will have a low finial PH also, i hope not but it may push low 4's
