I wrote to Château, this Is what they told me: "This Is a question that regularly comes up. We measured pH lowering in function of acid malt addition. The relation Is not linear. What Weyermann says Is not true in practice" There was this image. Orange Is what was expected, Blue Is what...

Listen to my story Today I checked FGs. The Daughter Beer looks like a very diluted version of the Mother Beer (which makes sense because that's what It Is!). While degassing (aka shaking) the samples, the Daughter Beer went headless in a minute, possibly matching the lack of head retention...

Nothing, in fact you may have done a decent NEIPA, although I admit that "decent NEIPA" sounds like an oxymoron

Grains were 85% Vienna, 10% Chocolate, 5% flaked barley. Pretty bold considering that for the small beer I used a yeast that should give me a lot of banana.

Well Today I brewed a beer: OG 1.035. Then I put some more water, to get about half the First beer's volume. I mashed again, boiled again, put hops only post boil. OG 1.006... very low. I pitched anyway a bit of SafAle 256, it should have a lot of attenuation, should be able to find...

Yes, but apparently there's a big difference in lactic acid content between the 1-2% of Weyermann and 4,5% of Ireks, so I'd guess a pound of Weyermann and a pound of Ireks aren't the same thing. I'd write them but Ireks never answers...

Weyermann's rule of thumb says "1% malt reduces 0.1 pH". Their malt is 1%-2% lactic acid, max 10% of the grist. But Ireks says max 5%: the reason Is that their malt is 4,5% lactic acid. Then there's Castle Malt: they don't provide lactic acid %, but state that their malt's pH Is 4.5. Since...

I was ignoring but seeing so many posts I became interested

Well if It's really just cold extraction and pH Is not related then It's nothing new... It's what I do with my tea.

There's also this little thing called non-enzymatic mash: you mash cold overnight to extract body, flavor and just a bit of fermentables to get a very low alcohol beer. Could be related?

I could too because I was close to do the same thing for my last brew, but in my case I was more worried of actual bugs than sourness

Would be interesting if you could take a PH reading during a brew day after this cold mash and compare It to the expected pH... (I'd do that myself but don't have a pH reader, although May buy a cheap one just to try)

I know about acid rest but It's not that. I mean cold water, about 5 C. In his book about traditional farmhouse methods Garshol mentions this as a relatively common practice among farmhouse brewers. And as with many traditional methods they don't really know why they do that, only that It works...

Apparently farmhouse brewers prepare the mash with a little cold water the evening before brewing. This Is thought to lower PH. Ever tried this?
