The mash went well with the uninsulated stainless mash tun. I might have to lag it when the weather gets cold but it's fine right now.
I pumped the mash liquor under the grist through a copper slotted exit manifold that I knocked up on Friday night. I thought this would be a good way of avoiding the grist compacting into the slots even before I started recirculating.
The mash temperature was maintained at 68 for an hour or more by recirculating, via a pump, through a home made heat exhanger. The new manifold worked well and was able to supply the recirculation pump for over an hour without the hint of a stuck mash.
The only issue I have is the efficiency seems a bit low. I ended up having to collect 60l and boiling for 2 hours to get the 50l I wanted at the correct gravity. I reckon I probably sparged too quick so I'll try longer next time.
I'm afraid there are no pictures as I was too busy making sure all the joins were tight and the electric were doing as expected. I'll take some next time.
