Mash Temps.

[euge]

How deep are you taking your readings? It has to be deep within the bed I've found.

And the reason I say that is even in my Coleman 70qt Extreme (dark-green) there was a 3-6 degree drop after 60+ minutes. Couldn't  keep the mash out of the upper 140's while aiming for 153. I was fighting with this for years until out of frustration jammed the probe in deep and my fingers were nearly in the wort.

The temp was spot on. :-)

i've been using the same cooler for more than 6 years and don't know what color it is, had to go out in the garage and look. its grey, will that work?

Blue...of course.  I got the blue one for the improved efficiency.

Yep...blue will get your efficiency up to 137%!

...but only if you mash on Sundays. 

OK, I'll bite...what is the history of the blue cooler meme?  I imagine someone thought the outside color of a cooler had an effect on its ability to hold a temperature?

the effects of high energy quantum particles are enhanced by the blue plastic of the coleman cooler. This causes the mash to convert past 100% efficiency by moving some starch backwards and forwards in time whilecausing the enzymes to vibrate in n dimension space. This means that a stout can be a porter and a CDA becomes paler than a wit beer while hefeweizens are pushed through the clove phase transition into the banana spectrum modified by mit space.

Scroll down.

These are the blue coolers you are looking for.
