Starsan

How long do you reuse a 5 gallon batch of starsan, if you transfer to empty carboys, etc?

As long as the PH remains at 3 or less. Cloudiness isn't much of a factor as many might think.

How do you measure PH?

 

[unionrdr]

You use litmus paper for that. They come in small strips in a little tube. You can get them at the local LHBS,or even lowe's home cheapo,etc. It'll have the color chart on the side of the tube for PH range.

Agree with the litmus test. But it can last several months. Test to be sure though.

Maybe obvious but a good reminder is always nice... start with distilled water and it will last a while. I make mine with DH2O and it will last through multiple bottlings, brews, and yeast starters then my the time i get through all that ive usually just lost enough volume that i go ahead and make another 2.5 gal.
