Do you use lump or briquettes in your Weber Kettle?
I switched to lump a few years back on my kettle. Mostly for higher burn temps, less ash to dispose of and that little bit of flavor they put off compared to most briquettes.
My wife recently brought home a twin pack of Kingsford because she knew I needed some charcoal.:doh: While the ash output is higher, I was surprised at the amount of heat coming off of the same amount of K-briqs that I normally use of lump. Interestingly enough, my cook times did not change much at all on the kettle for direct and offset grilling (not low and slow but grilling). I had about the same amount of coals left over between cooks, and was able to reuse the old briqs even lighting them up in my chimney with some new briqs on bottom.
What I took away from this brief experience going through a couple bags of Kingsford for kettle grilling, was that outside of the amount of ash and less of a smokey flavor, I couldn't tell much difference between it and the lump. K-briqs are cheap too, so I'm almost debating whether or not to pick up some more.
All that said however, when I recently bought charcoal, I bought lump.
For ceramic owners, does the kettle use way more than a ceramic?
I do not own a ceramic, but I know the answer is a definitive yes.
Do the kettles burn much more in cold weather?
I only use my kettles for higher heat cooking, both direct grilling and non-direct roasting. Lower temp cooking happens in my WSM's. For grilling, yes, I have noticed a difference, but since I can usually finish all of my grilling or roasting needs with one, maybe two loads of charcoal, it's not much of a factor I pay a great deal of attention to.
Are kettles less accurate holding temps
Less accurate than what? I am not sure what to say. I find they are really accurate for what they are designed to do, which in my opinion is high heat cooking, either direct or indirect. I haven't actually used a thermo to read cooker temp in my kettles in years, I just put the intakes where they need to be. That to me says steady and accurate. However, if I were to try and do a low and slow smoke in one, well, I would say it is less steady and accurate than many other cookers, but that is because I do low and slow in WSM's which are basically "set it and forget it". Some folks who regularly smoke in their kettles say it is very solid, but it does require a keen eye and attention. To me, that basically means less steady and accurate on its own without you there.
Hope that helped. If you are wanting one cooker that does smoking and grilling, and can afford ceramic.....GO CERAMIC!:thumb::wink: If a ceramic is out of your budget, you will never regret owning a Weber Kettle. You may wish to get a more "set it and forget it" smoker someday though.:wink:
