    Hi, I stumbled upon your page. I’m actually not a homebrewer, myself, but I toured a small brewery the other day. I am actually a stainless steel pipefitter, welder, and fabricator in the food industry; I travel the country building factories. A friend of mine who is into drinking unique beer suggested that I may want to look into brewing equipment fabrication since my specialty is sanitary stainless. I looked around a bit and was shocked at how expensive some of these things are. Is there a good resource online for learning about the functions and basic concepts of brewing equipment like mash tuns and other things?

    • Simply Beer says:

      i don’t know of one single resource, but you can look at what is being sold by the homebrew shops. The basic equipment would be a brew kettle and a burner, it goes up from there. There are brewstands, mash tuns, hot liquor tanks, boil kettle, fermentors and so forth. Check out what blichmann (

    Ok, so I’ve been brewing off and on for years now, and really a lot this year (2012). I’m looking to going to an all-grain system, now that I’ve mastered extract brewing. I’ve seen mash tuns made with coolers, but I really don’t like anything plastic touching my homebrew process. Perhaps you can make one of these for me? If so, how much and where do I send the money? Very cool.

    Looking at mimicking your setup to an extent and had some questions.

    I plan on putting the thermometer above the ball valve, & no false bottom, using this as my boil kettle. I plan to use the top fitting as a whirlpool and recirc through a pump to get that going.
    1.) What volume level is your top valve at?
    2.) should i put a ball valve on top to prevent spillage?
    3.) do you have any problems with your sight glass, both from heat on the bottom and liquid boiling out of the top?

    • Simply Beer says:

      Hi Bobby, I put the top value as close to the top as I could get, it is probably around the 14 gal mark. I didn’t use a ball valve on the top and haven’t had any issues with batches up to 10 gal. Never had any issues with the sight glass either, it comes out of the keggle around the 3 gal mark; I also have the bg14 banjo burners which put out a ton of heat. Hope this helps. Cheers!

    what are you using in the top port while recirculating?

    • simplybeer says:

      Sorry Zach, this got stuck in my spam comments. The top port is where the mash comes back through, I have a adjustable hose to gently push the wort back on the grain bed.

    What size male fittings are those on the top bulkhead and the ball valve?

  9. Frostbrewer says:

    Did you make your own bulkhead out of different parts from a hardware store or did you buy it pre-built?

    seems like you can get things a little cheaper if you go with brass.

    • simplybeer says:

      I bought a weldless bulkhead, brass ones are definatley cheaper, but they tend to oxidize(or tarnish) over time.

    which burner is that? I’m looking for one for my 1/4 keg kettle I am working on. (still trying to crossover to all grain)

    on the finished product, what is that tube in between the in valve and out valve?
