Lots of benefit in bigger mash tuns,confused wrote:Is there a benefit in larger mash tuns.
I ask because . . .
each time we walk around makro I stand and stare longingly at their ice boxes. They are solid plastic oblong boxes with lid all encased in 2 inches of moderate density expanded polystyrene. I guess around 50 - 60 litres (24 inches long x 15 wide x 15 high, approx) but the shape looks perfect, very flat vertical sides, looks ideal for the job.
Can't find any temperature / recycle codes on the plastic but I haven't really looked properly.
They are intended for frozen food deliveries and the like.
Higher gravity beers,
Larger brew lengths
Parti gyle brews

I would have thought that if they are food grade they should be OK.
They only really need to withstand 80 C as strike heat should be all they have to withstand for any real time
