    What the hell is causing this purple ring in my krausen

    Do you use brewtan b or any gallotannins? I've noticed a purple hue to the foam in mash and kettle whenever I use it

    Yet another DYI Plato scale

    What do you guys mean by time drift? Inaccuracies of measuring over time? What causes this? Software or hardware issue?

    How is weld polishing achieved, inside fermentation tanks?

    It gives you a fine line between polished area near the weld and the finish from the mill whether that may be #2 std, #4 brushed or #8 mirror. Similar to how it works when painting!

    How is weld polishing achieved, inside fermentation tanks?

    IMO 400g is good. The art is in not starting too rough and then having to buff it out. There's a sliding scale between using something aggressive to save time then to only use something less aggressive to hide the grind marks you just made. I always start with 80grit when sanding. I use the...

    How is weld polishing achieved, inside fermentation tanks?

    Flap wheels and Scotch Brite wheels can also be used on an end grinder depending on the project. Need to remember this can be achieved with a variety of consumables (not limited to what I've linked) but a good finish will always be performed by stepping up from coarse to fine. The art is a...

    How is weld polishing achieved, inside fermentation tanks?

    We use the red scotch by hand, yellow bristle wheels with a drill and custom made arbor and gray unitized wheels on a grinder. This is all for finishing. We typically use a 60grit sanding disc or 80grit pearl disc to carefully take down the weld and use the above three items to finish it off

    How is weld polishing achieved, inside fermentation tanks?

    I'm a professional food grade welder and that's what we use, of course you wouldnt use this with a flap wheel. Use the flap wheel to take majority of the material down and then apply blue tape, you then finish the stripe by hand with a scotch Brite pad. If your using an aggressive consumable...

    How is weld polishing achieved, inside fermentation tanks?

    Blue tape works well for striping welds. Look into 80-120 grit flap wheels, 3m gray wheels, yellow wheels and Scotch Brite

    Efficiency more than 10% higher than most brews.

    Try googling Braukaiser efficiency spreadsheet.

    PT100 constant calibration

    I have to constantly calibrate PT100 every brew day. Typically seeing around -12 offset throughout the brewery. I use cheap chinese PT100, wired with approx 60'-80' wire shielded 3 wire tied back to ground at panel side only. Would higher quality PT100's yield better results? I do have a m12...

    Pressure switch self sealing?

    I've narrowed down my chiller issue to this pressure switch, a bypass is allowing her to run again. Will there be a Schrader valve or self sealing port on the AC line when I attempt to swap out? Snug tighten ok?

    Building an unbalanced water profile

    @VikeMan Balanced being ionic balance NOT the name of "balanced" water profile etc... your responses are in alignment with what I'm asking about. When you mentioned it is impossible to have an unbalanced water, that's when I had the aha moment. Calcium chloride is ionically balanced, calcium...

    Building an unbalanced water profile

    I see that with the brewing software I use (Brufather), the estimated water profile after clicking auto is close to the target but not exact and I assume that is due to the balancing. It seems the software is guiding the user to add additions to maintain the balance. Is this simply put- a...

    Building an unbalanced water profile

    I understand the use of ion balance to check against inputs of source water. If using 100 percent RO water and one creates an imbalanced profile of anions and cations in the target water, what is actually happening here both in the software calculations and reality? Poor pH calculations...
