Newbie Question

[M Merrill]

I'm not new to smoking nor new to my WSM, but I need some help. I've had the brisket on for the past 3 hours. I started out with a grill head temp of 170°. Since then it has gone up 20°. I have all 3 bottom vents closed with the top wide open. I'd like to cool it down to 175°. So, can I close the top vent slightly or will that alter the taste of the meat?

 

[Enrico Brandizzi]

Yes, you can!
Probably 1/3. Not more, IMO. It will be rapidly effective.

also keep in mind that adjusting any of the vents won't adjust the temperature right away - usually takes 10-15 minutes to see a difference.

Why do you want to run that low a temp? Are you trying to make jerky?
