That's exactly the kind of response skin looking for but I disagree on your thoughts on it being braising your meat the meat only takes smoke the first couple hours this has been proven time and time again because I get same smoke ring and same smoke taste foiled or un foiled but I get much more tender and juicy when I foil it and let it cook in it's own fat and juices
Forget about whether it's braising or not for a minute, and let's just focus on the final product. You asked, so this is my experience. I've tried everything (on the wsm, cheap small offset, and UDS ) and I get a better or just as good overall product without foiling, at least for butts, spares, and briskets...at least most of the time. John brought up the part that fat marbling plays. You gotta keep in mind that when you're dealing with commodity meat, like most of us smoke, that often it can be just too lean, but it doesn't matter what you do. It's going to start drying out before getting fully tender. Foiling will help, but it's not going to magically turn it into great BBQ.
But when I say without foil, I mean just that. NO FOIL. Not even during the rest if I can time the cook right. You just can't argue with this: It doesn't matter how great your bark is when you foil, whether on the cooker or to rest....given enough time and temp, the bark will lose crispness. In other words, if the bark was "perfect" before foiling, do you think it's going to be as crisp and taste the same hours later when you unwrap it? There's always a tradeoff.
Now, back to the overall product, sure I get a little softer texture when foiling, at least for ribs and briskets, but that's not all I'm after. Maybe I'd be more inclined to wrap if I had a stickburner, since there's usually less moisture/more air flow, and a lot more smoke. I'd still lose the bark's crispness, though. But yes, foiling makes things get tender quicker. We pay for it though, not only in softening the bark, but also in some "dilution of smoke flavor". ("Foil diluting smoke flavor" isn't my words. That's Chris Lilly's of Big Bob Gibson...And yes, I know he foils ribs and briskets.) But do I ever wrap? Well, it's basically a tool I'll use, judiciously, if my cook timing is off, either way. I'm with John on the wrapping briskets with butcher paper. You got to try it. Only thing I might wrap in foil even when timing is perfect is loinbacks, since I can only afford the relatively lean ones at the stores. I smoke a LOT more spares.
Anyhow, I've got a question for ya, Colby. When you say you don't notice a difference, have you actually just pulled a butt or brisket off the pit, let it rest on a pan or board (still no foil!) to lose it's steam, then dig into it?
