Whats the internal diameter of the Buffalo 40 litre boiler?

How much grain would I need to mash for a 4 inch+ grainbed?

Thanks.

In volume 10cm (4") depth is approx. 10l.
I use a 10l bucket to measure my grain which is around 4.5-5kg usually.

Wow that's a lot of volume, how big do you recon your 5kg grainbed would become once it soaked up some water during the mash?

The 40l buffalo is no more than 40cm deep so 10l is about right if you look at like that.
I BIAB which the Buffalo is ideal for so have no idea about what size it would be when wet I'm afraid.
