My current mash tun is on the way out. After about 3 years of faithful service, it is losing heat more and more rapidly each session. In the beginning, it would loose 3 degrees or so over an hour. Now it's loosing upwards of 10 degrees. My method has not changed, so I'm not really sure why all of a sudden my cooler has lost its capability to insulate.
I'm torn between a 5 and 10 gallon round cooler. 95% of the beers I have made in the past 5 years will fit into a 5 gallon cooler, but I'm still leaning toward a 10 gallon MT. My only concern with going with the 10 gallon is the the unused space and any temperature fluctuation caused by said unused space. Seems to me that the fuller the MT, the less heat loss. I make 5-6 gallon batches and rarely do high gravity beers.
Is the unused space in the MT a concern to anyone? Does the partially full 10 gallon MT loose more heat than a mostly full 5 gallons MT? Or is it negligible.
