Getting correct temps on Weber kettles

[nolan]

Is there an old thread or does anybody have info. on preheating Weber kettles to the correct temperature?  I'm looking to find out how much charcoal is needed and how much to adjust the vents to get certain temperatures like 225, 250, 275, etc.  Several recipes call for higher heat around 350 and others call for something around 250.  I could just play around and waste charcoal, but I'd rather hit the ground running!  Any help would be appreciated.

This is the setup I use for BBQ on the OTG, the open space on the left is for about 15 fully lit briquettes. I leave the bottom vents fully open until I reach my target temp and then I close to 1/2. If the temp continues going up I shut the vents completely. Cooking on the kettle will get you a range of temps, not an exact formula to dial the exact temp that you have in mind.

I've done that also, and it works good.  I've found that the make of the briquet has something to do with it also.  Kingsford tends to burn hotter, Royal Oak a little bit cooler.  I normally use no filler hard wood briquets that I buy at a charcoal warehouse (yes, Memphis does have some benefits) that burns more like wood.  I also have the charcoal grates that you can buy for the Weber that burn consistently.

Ultimately, a therm is the ticket, and you've got to learn your machine (ambient temp, wind speed and direction, AND type of fuel all have an effect).  Been using mine for years and know it like the back of my hand.  It's kind of fun getting there.  MHO.
