  • I am worried you are not understanding this between all the information given. I will try another approach.

    5% divided by 10 equals 0.5%
    5% divided by 100 equals 0.05%

    5% = 50,000 Parts Per Million (PPM)
    0.5% = 5,000 PPM
    0.05% = 500 PPM

    Diluting...

    Don’t know too much about these but have met Mike Caringi a few times, the owner of chugger pumps. Nice dude, pretty sure he runs some other businesses and imports/exports pump parts. He’s out of the Treasure Coast I do believe.

  • It sure looks like calcium oxalate (beer stone) if you ask me. I can’t say I’ve seen organic material that remains whitish after caustic or acid.

    If you’re saying that it’s rough and sticks off the surface, this sounds like mineral buildup. I’m sure the lower...

  • Agree with the 90min target time. Extraction, not conversion, is likely your issue. You could do an iodine starch test to confirm conversion.

    Sieving grist is great to get you in a ballpark, but I have always adjusted the mill to match my brewhouse capability myself. If it looks too coarse,...

  • Connecting the pipes is nothing to be worried about at all. Just get some good quality PTFE paste and goop both the male and female ends. Tighten snug, but don’t get carried away. Use a shorter piece of pipe nipple (sacrificial) if you are really worried about galvanic corrosion.

    So, the do want account of every drop in your possession, but only if it has finished the manufacturing process. “Green beer” is not finished product (at least in my breweries).

    I have been through an audit before (maybe two?), and the govt has always been very helpful in explaining...

    Definitely try choking the line back, but in my personal experience this is too long of a draw to use a direct-draw setup reliably. Initial installation should have made use of either beer pumps or mixed gas to prevent a lot of the issues you are discussing. Separate regulators is obviously best, check...

  • Like I said, if you aren’t comfortable with dilution calculations, then use a calculator. I have previously suggested envirotech.com/calculators which already has many PAA varieties listed.

    The basic dilution calculation is Volume1 x Concentration1 = Volume2 x Concentration2

  • Dick is right in a sense, the lead will not be a "real" problem. Ironically "lead free" doesn't even mean lead free. It usually tells you somewhere in the fine print that the lead content is below 0.25%.

    All brass is likely to contain some trace amounts of lead, but...

  • I would suggest not wasting your money on sodium percarbonate unless you have a very specific application purpose for it. The PAA solutions you are going to find will likely contain 20-26% hydrogen peroxide in them already, so you are not likely to get any benefit from adding any sodium percarbonate...

    Hey Scott,

    Definitely do not use your casted wort for paying your taxes, IMHO. You are going to be paying taxes on product losses that happen post knock out. No sense in paying taxes on beer you can't sell. TTB really only has the legal authority to charge taxes on saleable beer, and not...

  • Don’t know SS Pro brewhouses directly, but have seen dozens of manufacturers and configurations. Thousands of industrial processes with unique applications.

    SS should really have sleeved your wires in fiberglass if they are running in a tube between the kettle interior wall and exterior...
