Homichef also makes 12-1/2", 14-1/8", 15-3/4", 18" and 19-3/4" lids. The OD of the vertical edge is 1/4" less then the advertised size for pot fit. So one could figure out if any of those sizes might fit their pots with some wrenching.


Oh...wait...subtle detail. so that's good to know...hmmmm. off to measure.


Howdy, first time post here.

Brandon, I have a 17.5 ID mash tun kettle as well and am looking to make a mash cap. Did you end up finding anything that works?

Welcome!

I haven't yet but haven't looked in a while. I still use a foam and foil kind of arrangement. But would still like to find a kettle lid that is the perfect match. I got to a point where price wasn't an issue. They'd run from around $15 to $50 depending on the source and probably the quality, but after scouring restaurant supply websites and such never found one that was around 17.25ish.

I had my own made custom, they are made from lexan flexible shatter proof see through. It's used in masks for fireman breathing apparatus, it will withstand 500°f without an issue, should be easy to have a 3/8 " thick piece custom cut.

The only worry with plastic being the plasticizers used in their manufacture can leach out especially when heated. Adipates, phthalates, sebecate etc. are not things I want in my beer.

I have not had any noticeable aromas or flavors YET but I will keep it in mind to be looking out for them. If I do detect any I'll be having custom stainless lids made.

I have to admit to side with Blisch on this one.

Be very careful with the plastics involved. In Germany we had platsic kettles deemed food safe. Later studies showed deposits backtracked to these kettles in children's kidneys. IIRC that was in the mid-90s. Arguably, nobody did a blind tasting and a thereof impeding vivisection of the subjects involved.... (like some hobby brewers seem to demand as irrefutable proof :P), but the sheer possibility of this being a problem makes stainless steel a sensible proposition.

Now, for those who conclude this is humbug, well, never mind my musings. After all, you are consuming most of it and will be the monuments and testament to these findings. These were never put to a human trial, so thank you for volunteering.

Mine aren't mash caps though, they are custom made lids totally sealing the system from outside air. That might make a difference

For your viewing and opinion , the white lid also has a small motor attached to the top of it sealed with a paddle attached for mash agitation

Ahh yes.. sorry, I thought you were speaking of having the lexan in contact with your wort.

My latest mash cap.

Is this the 14 inch cake pan? If so what is the OD with the silicone tubing?

I'm also wondering how good of an insulator this would be compared to a modified SS lid acting as a cap.

Since I do recirculated direct fired mash,I I try to keep as much heat as possible so whatever I build for my cap also needs to be a good insulator/dead space reducer
