A great way to get into all grain brewing. These 10 gallon coolers work very well as mash tons for five and ten gallon batches, as you will notice barely any temperature loss throughout your 1hr+ mash. Comes with a stainless ball valve cooler kit, upgraded leak free bulkhead and a 12 inch stainless steel false bottom. The barb size on the mash ton for the output is 1/2inch. All metal parts are stainless steel.
