a ten gallon mash tun cooler. Comes with ball valve, probably needs a new stainless filter screen- 10 dollars not shipping, you pick up
5 gallon glass carboy or two - 10 dollars, not shipping, you pick up
6 gallon glass carboy- 15 dollars, not shipping, you pick up
50 foot stainless immersion...
So that probably explains it. I just used mine for the first time over the weekend and wondered if I was doing it right (even though I did have directions still :) )
Did you have the fitting on the keg while doing this? It specifically states on the charger package they can explode if it isn't attached to the keg when you screw it on is why I ask.
My son is 4. He understands what the difference between mashing at a low temperature and a high temperature will produce. There is nothing wrong with them knowing about it. My son stirs the mash takes temps and adds hops.
