I’ve read that the coleman 70Qt extreme cooler was a great cooler to convert to a MLT, but wanted a little bit larger one. So I got the 100qt version online thinking it would work out the same. On receiving it I’m second guessing my plan. Take a look at these pictures. 

I’m concerned the ridges inside will create a channeling effect when batch sparging. I don’t think the 70Qt version has these. 

The other thing that seems different from the 70Qt version is the drain channel. Pictures from the 70qt version look like there is a distinctive channel (and the sticker on 100qt version looks like it does too). However, the channel appears non-existent and the bottom looks flat (though I haven’t tested to wit the is a slope or not) 

What are your thoughts about the 100qt version? Should I keep it or look for a different cooler?

As with many posts I’m working to step up to all grain brewing, but I don’t want to have to do this again in a year so I’m trying to figure out the right criteria for selecting a kettle. I really don’t want to think in a year from now, “If only I had known …. before I bought my kettle”.

From what I’ve read here is my starting point
1) Choose stainless steel:

as opposed to aluminum which will pot over time

2) Choose 20G or greater kettle size:

I’d like to be able to do 10G batches if my heart desires. A 20G kettle will allow for high gravity 10G batches, smaller kettles will make things moer challenging. also, this eliminate the frequently suggested keggle idea as this is only a 15.5G kettle.

3) Can live without built in valves for now, but can upgrade late if desired:

I’m brewing without valves with no problems. I know valves will most likley make things easier, but it isn’t a firm requirement. Additionally, and perhaps more importantly its possible to punch/cut/drill holes and add valves at a later time, if/when desired

Open questions
4) Does 1-3 sound right, particularly #3?

I’ve read a lot of forums and such so far to get here, but I’m new to this and from what I’ve learned from doing extracts is that there is a lot to thing about when.

5) Does base thickness matter?

Seems like there are ranges from 1mm to 5mm. With most hovering around 2mm. I’m guessing this is for even heat distribution, but how much is enough

6) Does side thickness matter?

ranges from not specified to 1mm to 2.5mm. Seems like just about anything would work. Any issues with punching holes on a thin one later to add valves?

7) Need to be NSF certified?

Some claim to be, many don’t specify

8) build construction/materl

I’m not too familiar with the things I’ve seen a) aluminum wrapped/sandwhiched in stainless steel, b) 20 gauge stainless steel, c) 18/10 Stainless Steel, d) 18/10 T304 stainless steel, e) 3-Ply Bottom, and many more

9) Anything else?

I’m probably way over thinking this as I’ve seen posts from many happy brewers with pretty much all the pots I’ve taken a look at, but I haven’t been able to find any criteria for choose a kettle other than size recommendations. thanks for any feedback.

I’ve only been making beers for a short while and it seems that I’ve had so many questions about how to go about doing it while I was in the middle of making the beer. So I wrote down my game plan for specialty grain brewing process on my little website (not a commercial site). I’ve also pasted the text in here in case you don’t care to go to a unknown location, but I didn’t mess with the formatting. Let me know if you have any advice and perhaps this will help someone else. Thanks.

Specialty Grain Brewing Process – Ales

I have a brew that was supposed to have an OG of 1.080. When I measured it I got a reading of 1.077 after the correction (1.076 at 66 degrees). I took several measurements, spinning the hydrometer each time and consistently got the same result. I have a slight boil over, but other than that there really isn’t anything I can figure out how I didn’t get the expected OG. On top of that, using brewer’s friend extract calc I should be at 1.085 (5.25G water, 12 lbs LME).

Any ideas where I might have messed up?
