Why do people keep trimming the fat cap off brisket before smoking?

I swear every third backyard cook I see on YouTube or Instagram is hacking off that whole fat cap like it's a crime. Man, you need that cap to render down and keep the meat moist during a 12 hour smoke at 225 in my Oklahoma Joe. Why would you expose the flat to direct heat like that? Has anyone else had luck convincing people to leave it on?

Jump right into convincing them by showing them what happens when you leave it on. I've got a friend who used to trim his brisket down to bare meat, and after 10 hours the flat looked like shoe leather. I finally made him do a side by side with one fat cap on and one trimmed. The trimmed one dried out way faster and had a tough bark. Now he leaves at least a quarter inch on there and his briskets come out way more tender. Just tell people to trim the hard fat but leave that soft cap alone, it's the difference between a dry flat and one that pulls apart.

Wait, your friend used to trim the brisket all the way down to bare meat? That's like, the number one rookie mistake I see people make and it makes me cringe every time. I mean, that side by side test is genius, @wade_dixon, because nothing convinces a stubborn person like seeing it with their own eyes. I've watched guys pull off a brisket that looked like beef jerky and they swear they did everything right, but it's always the fat trimming that gets them. Leaving that quarter inch of soft cap is a must, it's basically a built in moisture shield for the whole cook. It just blows my mind that someone would think scraping it all off was a good idea in the first place.

I mean, wade_dixon, that side by side test is a solid idea, but I gotta wonder, how much of that shoe leather problem is actually about the trim vs. just someone not knowing their smoker? Like, I've seen guys leave a full inch of fat on and still end up with a dry flat cause they didn't spritz or their temp gauge is off by 30 degrees. Do you think the fat cap really saves you from those other mistakes, or does it just give people a false sense of confidence that their cook can go south in other ways? Idk, maybe it's just me, but I feel like trimming is one piece of a bigger puzzle that a lot of folks ignore.
