I'm working on a split back and that requires me to perform a secondary mini mash for additional extract and color. Will the following convert? Im trying to solve for how much pilsner malt is needed to allow this to convert as much as possible. How does one figure this out? Assume 150-156F for...

Looking for some feedback on a recipe I put together for my first NA beer. Going for an easy drinking crisp beer- blonde ale hopefully lager-like. I wanted to use a more complex base malt but had Pilsner on hand so I pumped up the specialty malts a bit. Hops are reserved hoping for a balanced...

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...

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?

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...

Having a hard time finding brewtan B in stock at commercial sized packaging. Anyone know of a place to purchase or a substitute?

I am looking to reverse engineer Redbull energy drink and brew something similar. I am able to reference the back of can, nutritional facts and general online searches to solve for grams/oz of caffeine, taurine, vitamins etc. Where I am stuck on is pH and additions that affect pH such as the...

We typically target kettle pH around 5.2. I heard some interesting ideas yesterday (Master Brewers Podcast Ep 217) regarding dryhops effect on finished beer pH. In the podcast, he mentions 1lb dryhops per bbl of wort could raise finished beer pH by .1. This is a rough figure as the alkalinity of...

When is the biotransformation Window?

Most of us know yeast convert sugars to alcohol. What exactly is going on when lactobacillus produce lactic acid?

After three years of hard work our brewery is finally opening today!

Looking to perform an initial charge on a used split unit we bought for our cold storage. This is a split unit and we have installed about 40' of service line in which we need to vacuum. I spoke with an AC technician and this is about as much information I could gather. I have gauges...

If a fairly large kettle say 40" diameter is completely sealed with the exception of a 6" vertical vent to roof (approx 15') would installing an adjustable port opposite end of the exhaust port assist with increasing the draft through the exhaust port? Does the cool air coming in assist the hot...

Anyone have a good source for a quality sieve set? Which ones would you suggest?

I have a PID controlling cleaner temp in keg washer. SSR is showing off but is stuck open causing overheat issues. Even with the installed heat sink, my issue may be caused by excessive heat or poor SSR. I bought a 5 pack on Amazon and most of them show the same symptoms. Heatsink and SSR are...

I'm in the process of building my own coolbot to control walk in cooler AC unit. I need a heater that tricks the AC thermometer into thinking the room is warm. I see some guys using light bulbs but Id like to use something smaller and more professional, something like the heaters in 3d printers...

I have a controller that NTC and digital thermometer inputs. The manual doesn't say anything about what type of NTC or digital thermometer. Not sure what a digital thermometer type is? I assume I'll have to measure ohms at a certain temp to figure out what the NTC probe type is? Is 1-wire a...

How important is the purity of co2 in brewing? I have one supplier that uses a Zahm Nagel to check purity and another that does not. The supplier that does wants 80/cylinder refill and the one that doesn't is around 50/cylinder. Both claim this is food grade co2.

I'm looking to use water from HLT to rehydrate yeast. After sparge my HLT is 170F. Any reason not to pull from HLT, cool to hydration temp and rehydrate the yeast? I do not add anything to my HLT but RO water.

I'm looking to write a script that reports temperature change in a set amt of time. How would I record a value and use it to continually work towards averaging out Deg F/Min or Deg F/Hr?
