Mash tun

[MightyMouth]

I've always used them. I get a consistent 60% mash efficiency from mine. Here's some pics of a guy who sells them online.

60% sounds very low as an average, On my first AG I got 59% after I messed up the sparge, my second was 76% and my third was 69% on a high gravity beer.

It is low. I batch sparge. I will never fly sparge again. Just not worth the trouble IMO.

Was it easy to fit a strainer to the tap?[/quote]

Yes dead easy. There is a spacer going through thats a 3/8 thread on the inside. Buy a 3/8 to 1/2 converter and use this as the nut to hold the tap on. Then a tap conector just screws onto it. Choose what size tap contector you want and its just all push fitting your strainer from there on in.

Good tip if you want to bend copper pipe for a strainer. Cut several slots about 2/3 the way through where you want the bend. Put it in a vice and just pull it in the direction you want. More slots for a bigger bend.
