I ran a couple of temp test runs during the week using Kingsford blue and Stubb's natural briquettes. Having never used Stubb's before til now (bought a dozen bags during their 2 for 1 sale back in April) I was surprised that it did not burn as hot and did not last as long as the Kingsford in my new UDS.

My charcoal basket size is roughly 13" diameter by 10" tall, mounted 3" above the ash pan. I used the Minion method. I ran these empty (no food).

2 chimney full of Kingsford ran steady at 250F for 12 hours where the same amount of Stubb's the next day only lasted 6 hours tops and required additional vent openings to hold 250F.
Is this difference typical between these two different types of briquettes?

Thanks!
