How long will a cooler mash tun last?

I was talking to my LBHS owner today and he mentioned something that I'd never considered. I'm going all-grain soon and said that I'd be converting a cooler to use as a mash tun. He said that's a fine way to go, but that after a certain number of batches (12-15) the plastic within the cooler will warp. So there's only a finite number of batches I can do with this equipment (he was advocating just getting a keggle and going with stainless from the beginning).

Have any of you had a problem with this? If so, how long does the cooler last, and what are the difficulties associated with mashing in a warped cooler? This seems like the most common method when going all-grain, but I've never heard of the cooler having a short lifespan before.

Thanks

Re: How long will a cooler mash tun last?

Don't personally know the life of an igloo mash tun.. never thought about it.

But I can say 12-15 is way off as I have 40+ batches done in mine. I do use boiling hot water to bring my mash tun to temp (I think if anything is gonna do it, it would be this step) and mine still works like the first time. The floor of it is somewhat warped, but nothing I have ever been concerned with as it suttle and doesn't leak.

Re: How long will a cooler mash tun last?

Denny's number is in the mid 300's on the same cooler. That guy is filling your head with crap.

I've got two - one that's had close to 30 batches and the other that has had about 10. Both are fine and haven't warped at all.

Awesome. Thanks for the advice. I thought it was weird when he mentioned it, since I had read nothing about it. But it does make sense.

Either way, I appreciate the responses.

You have to get a Green cooler for it to last forever. Besides everyone knows the green cooler holds in the heat the best. :wink:

Yeah strictly based on what I've read warpage is the least of anyones worries in a picnic cooler.

Gosh it is true. How great that your LBHS "meister" is philosophical. Brewers and there gear have a finite time on the old globe. I have seen some stone bowls for Chicha de jora that had a good 11,000 years on them. :mrgreen:
Brew like the wind, Chinaski1217! May your tun work long and hard at warp speed.

Cheers

Re: How long will a cooler mash tun last?

I've used mine for 11 years and 369 batches. It's warped some, but that has no effect on its usefulness.
