Can I use this to passivate stainless?
Christopher Baas on Aug 31, 2020
BEST ANSWER: No. Passivation can be achieved by using citric, nitric, or phosphoric acids in high concentrations. We typically recommend a small dab of pure Starsan acid sanitizer as most brewers have it on hand. If you want something less expensive, citric acid mixed with an equal weight of distilled or deionized water should do the trick.

Good product
I use this product fairly regularly and find its addition to be predictable and consistent.

I use this to drop the pH of the mash. I've also used this to sour a Gose, and it worked really well.

Definitely not basic
Used it to pre-acidify my wort for a kettle sour. Worked exactly as intended, preserving head retention. Definitely recommended for this purpose.

A little DOES go a long way
I just started using this to adjust pH. 3ml was enough to drop the pH of my mash from 5.7 to 5.4. Tasted it once, too. I have never tasted so intensely sour.

Just used this to sour a Gose without bugs. Turned out great.

My beer has improved
My homebrew has really improved once I started adjusting my mash pH and building my water. My efficiency went up and it just plain tastes better. Because I started making both of these adjustments at the same time, it is hard to pin point which one made the biggest differene, but my money is on fixing my pH.

Crareful with levels
I use this to adjust pH during the mash. Just as others have noted if you add too much you will sour your beer. A little goes a long way and make sure to wait a while before checking pH again.

Powerful stuff!
I bought this to add a hint of sourness to a stout without having to deal with bugs or a sour mash. I tried to read around an ounce of the acid per 5 gallons of beer seemed like the consensus. Well, that is WAY too much. I ended up with ten gallons of lemonade-sour beer. So, learn from me. For a five gallon batch of beer a quarter ounce will give a hint of sourness. A half ounce will give a noticable sourness (too much for my taste) and anything more than that is a mistake.

I have no experience using this for mash PH adjustment.
