Hows everyone doing? My name is Shane. I am new to the smoking world. I just bought a MES 30 digital. I have already seasoned it and am ready to go for tomorrow. I am smoking a brisket using mesquite wood chips. Couple questions for yall. Do you want to leave the vent on the top open at all times or closed? I have been told to put apple juice in the water pan instead of water and to spray the meat about every two hours with apple juice. Any suggestions would be great. Thanks for the help.
