The owner's manual states that it will use ID sizes of 1/32 in to 5/16 in. Assuming a wall thickness of 1/16 in, the answer to your question is 7/16 in. I used Norprene tubing 7/16 in OD, 5/16 in ID. Flow rates with this tubing are listed at 121 to 3400 ml/min. You can also use silicone or...

So, if I understand the reference, the rate limiting issue with DMS is the conversion rate from SMM as opposed to evaporation of DMS. Thus, boil length helps because during a longer boil, more of the SMM gets converted into DMS which is then volatilized. Half life of SMM conversion to DMS is...

I repeated the experiment today paying closer attention to volumes and thermal expansion, etc. It was also daytime and I could see the lines better on my stainless ruler. 40% power: drainage temp: 152-159F boil off: 0.47 gal (3.2%) 50% power: drainage temp: 177-185F boil off: 0.67 gal...

I have a well - my water is about 55F.

I just added the steam condenser to my BK and performed a "water drill". I have a 4500 watt element that I run at 85% power which yields a 1.2 gal/hr boil off with a preboil volume of 14 gal. My house water pressure is 30 psi and I am using the 6 gph nozzle. Here are my results using 50%...

Many things at the homebrew level do not translate when you get above 1 or 2 barrels. Above 2 or 3 barrels, HERMS and RIMS will not effectively raise temps but may help maintain temps. The thermal mass of the mash will hold temps pretty well for an hour in an uninsulated SS vessel. Obviously...

I think you will end up regretting your decision to build a BIAB for 10 barrel batches. For the cost of building the infrastructure to haul up the basket you could buy a MLT. Dry grain for a 10 barrel batch will be over 500 pounds. A pint per pound of retained water will add another 500...

I am about to pull the trigger on this. Any updates? Anybody having issues with DMS? Have any of you brewed with a large percentage of pilsener malt?

I would add the corn to the original mash because it will not convert. Beta amylase will no longer be active and will be mostly contained in the first runnings. FWIW, Biscuit is not usually used in a cream ale. If you make cream ale with all second runnings, it will likely not taste good. I...

Your erlenmeyer is not big enough. Is your kettle 55 gallons or your batch size 55 gallons? I used to brew 30 gallon batches (BK was a 55 gal SS drum) and usually made a 5 gallon starter. You could use fewer vials if you step up the starter. You could make a starter in your erlenmeyer and...

Add it during the last 5 to 10 minutes of the mash. This will add color without adding a roasty flavor.

+1 I have used an upright freezer for both a 14 gallon and 42 gallon conical. I mostly brew lagers so I have never needed a heater. Craiglist is your friend. Make sure the freezer's coils are not part of the shelves.

Here is a simpler solution:

If you use a conical, you can dump and discard the bottom portion of the yeast which includes dead yeast, trub, early floccers, etc. I repitch the remaining yeast as many as 8-10 times without washing. YMMV.

Harmless! That said, it would be easy to clean up with a 3M scrubbie and some barkeepers friend.

Looking at your pictures, I wonder if you had a bad crimp connection that overheated. Did you use a ratcheting crimper? The crimps on your 10 gauge wires look questionable.

There are 4, as I oxygenate my starters as well. I brew mostly lagers and ferment at 48-50. I typically have airlock activity less than 12 hours after pitching.
