Looking at Bru’n Water and I see that this recipe calls for .35ml of lactic acid to be added to the sparge water. How would I measure this small amount of lactic acid? Even with small syringes, they are measured at 1ml increments.
Would I need to convert to UL and use a pipette?
Cheers!
That small amount says you don’t need to add any acid. It sounds like your water alkalinity is already very low. RO?
as Martin said, probably don’t need it at that amount.
I use a 10ML graduated cylinder that makes it easier for seeing smaller increments. you can also weight it with gram scale. 1ml 88% lactic acid = 1.21 grams .
That’s right Martin, it’s RO.
You don’t need to add any acid to RO sparge water. There’s no alkalinity in RO to neutralize. The mash is different because your grist (depending on it makeup) can produce a higher pH than desired, which you then sometimes need to reduce with acid. No worries.
Sorry about that artifact regarding acid in sparging water in the Bru’n Water software. If the water already has less than 25 ppm alkalinity, then sparging water does not need to be acidified. That small amount of acid that the program is reporting, is a rounding error. I need to put another bit of code in there to zero out that artifact.
I use a small syringe to measure acid.
Of course you do.
You grew up in the '60s
Unless you’re using a 1mL syringe. Some of us have pets small enough to require those from time to time.

Yeah, but we didn’t use them then. This one came with my Zymatic.
Nobody use the brown lactic…
I do have some 1cc syringes that can measure to the hundredth of an ml, but as others have said, if you need that small of an amount you probably can make do without any. I normally use a 5cc syringe with 0.2 ml graduations to measure my acid additions.
I dilute my 85% phosphoric acid down to a lower concentration and use a 5 mL pipette to measure.
It just makes it easier to measure out the smaller quantities, at least for me.
I use a TB syringe. Pretty easy to measure small amounts.
Uhhhh…Too late for that one my good man!
