I'm looking to attatch a thermometer to my mash tun. How far should the probe stick into the mash? Is there any science with this or just recomendations?
I use a 4" above my valve, a temp probe in a thermowell coming out of the valve (a la Lonnie Mac) and a digital probe hanging in the tun. When I stir, all three probes are in sync. Helps me keep a more consistent mash temp.
