Why are boilermaker kettle bottoms so dang thin?
« on: August 08, 2014, 01:23:57 AM »
John Blichmann is as near to a homebrewing engineer saint as one can get, so please be advised this is not an attack--merely a question I keep asking myself, so I thought I'd quiz the forum.

Why are the boilermaker brewpot bottoms so silly thin?

Yes, the pots are notable for their stiffness and durability as well as build quality and features at an incredibly light weight.  True and true.  But why no sandwiched core to distribute direct fire heat and minimize scorching?  That's worth a little more weight in my book.

I can't tell if the generation 2 pots are thicker, but they don't advertise their bottoms as having any enhancement.  Bummer.

not trying to sound like a prick, but have you emailed him asking?

Hmmm, I was hoping for a bit of community therapy.  Starting with a bunch of yeah-I-know-what-you-mean's and maybe going somewhere useful, like suggestions of heat dispersal solutions and who knows what.  Cheers.

From spike brewing regarding why they do not sell clad kettles.

Q: DO YOU SELL TRI-BOTTOM KETTLES / DO THESE KETTLES HAVE AN ALUMINUM SANDWICHED CORE?

A: No! We actually used to sell the 'tri-bottom' kettles but after testing and customer feedback we stopped selling them. Somewhere the rumor got started that the tri-bottom kettle is the way to go for brewing; it's not true. Based on our testing, our 1000's of satisfied customers and other companies that offer kettles we've concluded that a tri-bottom kettle is more marketing ploy than functionality. These tri-clad bottom kettles are meant for kitchens making thick soups, sauces and stews that tend to scorch. They cost more and weigh much more than a single layer kettle that was designed for brewing. The only real benefit of a tri-clad kettle is if you want to use it for induction heating.

I use the morebeer kettles with bottom the same thickness/ thinness as the walls. They work great

I use those as well.  Extremely heavy duty.  Bottoms of my 15 and 26 are much thicker though.

Also, they appear to be tri-clad.  http://morebeer.com/category/morebeer-brewing-kettles.html

I have kettles that are both tri-clad bottoms and regular stainless bottoms... both work great with no scorching.  I also have some really cheap stainless kettles that are extra thin... There is extreme scorching using those.  So it really does depend on the thickness of the stainless... If you can't deform the pot with your hands and the bottom is the same thickness I would say your fine... If you can deform the pot with your hands then it will likely be able to scorch your wort.  Very scientific I know ;-)

From what I've seen from people that have the blichmann pots they do not seem to scorch anything.

This falls under fixing problems that don't exist.

There could also be the variable of heat source distribution. Banjo burner>BG10 SP10>jet burner.

The Blichmann burner has a banjo type.

I use about 2 cups when I make ramen using a pot on the stove. You know, the suckers method. I would imagine 1 cup, maybe 1.5 cups.

Oh sure...now they have them.  Do you know how many times I've passed out after a night of drinking waiting for my Ramen noodles to cook?

LMAO.  Yeah, shaving the 3 minute cooking time down to a minute and a half makes all the difference to me. I wonder if it makes them taste any better.
