I finished making my mash tun with a rubbermaid 12 gallon cooler and tonight I tested how well it would hold the heat at about mash temp (just the manifold in the cooler).
Added 5 gal. "strike water" at 149.5 F
At 36 min. - 144.5 F
At 60 min. - 141.5 F
Is this too much heat loss? I didn't pre-heat the cooler, so I suppose that might make a bit of difference. Also, is there an amount of volume that is acceptable to lose? I figure over the course of an hour I may have lost about 4-6 oz. due to leakage.
