Alfred's 11.5 gallon mash tun, with SS ball valve
This is an 11.5 Gallon Igloo Cooler for use as a mash tun for all grain brewing. Insulated coolers are widely known for their ability to hold temperatures for the duration of the mash. Lightweight and durable, this is a great value as the ball valve is included. You still need either a false bottom or bazooka screen.
If you are mashing in your kettle and struggling to hold temperature, this mash tun is your answer.
