 In a recent post, Martin said pertaining to 88% lactic acid—-“1ml per gallon 88% lactic is no problem at all. Its around 1.5 ml/gal that the 88% lactic will definitely have flavor impacts.”

Are there similar parameters to using 85% phosphoric acid? And if so what are they? And above what level is there a taste impact? And what is the taste?

Thanks!

Great,  thanks so much. Having not used bru’n much, confirmation that I’m doing things correctly really helps. Appreciate it.

 OK, so I’m using the program correctly? That just seems  like a large amount of acid addition. , I guess it’s because I chose to buy the 10% on accident.

 Mash water volume 5.3 gallons, Sparge water volume 4 gallons, post boil volume 6.5 gallons.

Round two on trying to adjust my water and get the correct mash pH. It seems like I’ve got something wrong especially with the amount of acid I need to add?
Doing a wit beer:  2row 5lb4oz, white wheat 4lb4oz, flaked oats 1lb.
Existing water:    ca56, mg9, na11, sulfate15, cl2, bicarbonate204, caco2-168,
Mashing profile:  ca80, mg17, na11, sulfate46, cl44— after additions of some calcium chloride and some Epson salts.

Shooting for a mash pH of 5.3?
I have both lactic acid 88% as well as phosphoric acid 10%. I chose to use phosphoric acid in the program (because I read about taste contributions for lactic acid?) but it is saying that I need to add 41.4 ML of phosphoric acid to the sparge and 79.5 ML phosphoric acid to the mash.

 I’ve never done this before but those seem extremely large contributions of acid? Am I doing something wrong?

 Thanks in advance for any help/advice.

 That all makes more sense than anything I found on the web. Thank you

All Grain Brewing / Lodo, but we oxygenate? Don’t understand
« on: May 07, 2018, 12:32:57 AM »
 I realize that I’m late to the party on this one and I’m probably opening a big can of worms but ........
 How does it make sense to go through all of the lodo steps and then prior to pitching yeast, oxygenate the wort?    Is the oxygen somehow different from 02 introduced during HSA?

 Just wondering what people do with their beer lines between kegs if they have to leave them empty for a while?   Are clean mine with BLC then flush them with water. Then I try to get as much water out and leave them till next time but there is always some residual water left because my beer lines are 10 feet and not easily removed.   Then I worry that some Funk has been growing in the residual water and clean and flush again right before I hook up a keg and it is a pain in the butt to do it twice. If I left them full of water or starsan, I’m worried they will freeze because I keep my kegerator pretty cold. Anyone have any brilliant ideas?

 Cool, thanks for the advice. Maybe a little flaked wheat will help. I’ve been doing everything on that list except for letting trub clear prior to transferring to fermenter. I do whirlpool but haven’t been letting it settle afterward.  I’m going to do this on the next batch. Also going to recirculate my mash. Maybe those two things will help also.

Anyone do this for mouthfeel or head retention?  (I’ve been having trouble with retention) If so how much.  I use and like it in porters and stouts but never tried in anything else.  If so, does the mouthfeel make it seem less dry if I’m mashing low?  Just wondering....

Crap, I didn’t mean for this to turn into a carapils debate.  Just wanted to see what people like for an APA malt bill.

All Grain Brewing / APA malt bill advice
« on: April 03, 2018, 07:34:56 PM »
 I’m trying to write recipe for an APA as follows:   OG ~ 1.050, IBU~45-50,  using equanot and mandarina bavaria mostly late/whirlpool.   Since those two hops are tropical, I want the malt bill not too sweet or complex.  I want it hop forward so the malt doesn’t detract from the hop taste.   I was thinking like something as follows for the malt....

95% 2 row
2.5%  Carmel 40
2.5%  Cara-pils

 Can anyone give an opinion on an APA Malt bill that they’ve done or had that they recommend for something like this?
Thanks.

 When I’ve been doing this, the beer is not flat. After I add the hop pellets I just twist the cap back on and it actually kept its carbonation great for three days.
