You've been lied to about brats. Most people think you just throw them over a screaming hot propane flame until the casings split and all that glorious fat leaks out onto the deflector shields. That’s a mistake. A huge one. If you want a brat that actually snaps when you bite it—and releases a fountain of savory, smoky juice—you have to slow things down. Speed is the enemy of the bratwurst.
So, let's get into the weeds. How long to smoke a bratwurst usually comes down to about 45 minutes to 90 minutes, depending almost entirely on your smoker's temp and the thickness of the links. It's not a marathon like a brisket. It’s more of a sprint-walk. You’re looking for that sweet spot where the smoke penetrates the meat but the casing doesn't turn into a piece of chewy plastic.
I’ve spent years hovering over offset smokers and pellet grills, and I can tell you that the "low and slow" mantra applies to sausage just as much as it does to a 12-pound pork butt. If you rush it, you ruin it.
The Temperature Game: Why 225°F is Your Magic Number
Most folks ask about time, but they should be asking about temperature. If you crank your Traeger or your Big Green Egg up to 300°F, you’re basically just roasting them. You’ll be done in 20 minutes, sure, but you won't taste the wood. To get that deep, mahogany color and the distinct ring of flavor, you need to stay low.
Set your rig to 225°F. At this heat, a standard raw bratwurst takes roughly 60 to 90 minutes to reach an internal temperature of 160°F. Why 160°F? Because that’s the safety threshold for ground pork, but it's also the point where the fats have fully rendered without the sausage drying out into a sad, shriveled nub.

Does the Wood Type Change the Timing?
Not really. But it changes the soul of the meat.
If you’re using a heavy wood like hickory or mesquite, you might actually want to pull them a little earlier if you’re sensitive to smoke. Bratwurst casings are thin. They take on flavor fast. Fruitwoods like apple or cherry are the gold standard here. They give the pork a slightly sweet edge and a beautiful reddish hue that looks incredible in photos. Plus, cherry wood doesn't get bitter if the ride goes a little longer than expected.
The "Beer Bath" Debate: Before or After?
There is a massive divide in the BBQ community about whether you should soak your brats in beer before they hit the smoke. Some guys, like the legendary meat scientist Greg Blonder, argue that soaking raw meat in liquid doesn't do much for internal flavor because the molecules are too large to penetrate the casing.
Honestly? I think the "hot tub" method works best after the smoke.

If you smoke your brats for an hour, get them to 150°F, and then drop them into a pan of simmering beer, onions, and butter on the grill for the last 10 minutes, you get the best of both worlds. The smoke is already locked into the meat, and the beer bath adds moisture and softens the onions you're going to pile on top anyway. If you soak them beforehand, you're just putting wet sausages in a smoker. Wet meat doesn't take smoke well. It creates a barrier. Dry those links off with a paper towel before they go on the grates. Trust me.
Signs Your Brats are Actually Done
Don't just trust the clock. Every smoker breathes differently. A windy day in January will change your cook time compared to a humid July afternoon in Georgia.
- The Plump Factor: When the sausage looks like it’s about to burst, but hasn't yet, it's close.
- The Color: You want a deep, burnished copper. If it still looks greyish-pink, keep the lid closed.
- The Temp: Use a high-quality instant-read thermometer like a Thermapen. Poke through the end of the sausage, not the side, to keep the juices from spraying out like a leaky garden hose.
Common Mistakes That Ruin the Experience
The biggest sin? Pricking the casings. People think they need to "let the fat out." No. That fat is the flavor. That fat is the moisture. If you poke holes in your brats before smoking them, you’re essentially draining the lifeblood out of your dinner. You’ll end up with a grainy, dry texture that even a gallon of spicy brown mustard can't save.
Another one is overcrowding. If you pack 20 brats onto a small smoker shelf, you're blocking airflow. Smoke needs to circulate. Give them at least an inch of breathing room on all sides. This ensures the "how long to smoke a bratwurst" question stays consistent across the whole batch.

Why Quality Meat Changes the Clock
If you’re buying the cheapest, mass-produced brats from a big-box grocery store, they often have a higher water content and more fillers. These tend to shrink more aggressively. If you can, go to a local butcher. Fresh, hand-stuffed brats usually have a coarser grind and a higher fat-to-lean ratio. These take a bit longer to render out properly, maybe closer to that 90-minute mark, but the texture is night and day.
Standard grocery store brands like Johnsonville are fine—they’re consistent—but they’re designed to be foolproof. A real butcher brat is a different animal. It’s thicker, it’s denser, and it rewards the patience of a slow smoke.
Pro Tip: The Reverse Sear Finish
If you want that iconic "snap" when you bite into the sausage, you might find that 225°F doesn't quite crisp the skin enough.
The fix is easy. Once your brats hit 150°F, move them directly over your heat source or onto a hot cast-iron skillet for literally 60 seconds per side. This flash-heating tightens the casing and gives it that professional finish without overcooking the inside. It’s the difference between a "good" brat and a "people will talk about this for weeks" brat.
Essential Next Steps for Your Next Smoke
Stop guessing and start measuring. The next time you fire up the pit, follow this specific workflow for the best results:
- Dry the meat: Take the brats out of the package and pat them dry. Let them sit on a wire rack in the fridge for an hour if you have time. Dry skin takes smoke better.
- Target 225°F: Don't chase high temps. Keep it steady.
- Use Fruitwood: Pecan, apple, or cherry. Avoid the heavy stuff like mesquite which can turn the casing bitter.
- Pull at 160°F: No higher. Carryover cooking will take it to 165°F while it rests.
- Rest your meat: Give them 5 minutes before putting them in a bun. This lets the juices redistribute so they stay in the meat and don't just soak the bread.
Smoking brats isn't rocket science, but it does require you to ignore the urge to hurry. If you can give it an hour and fifteen minutes of your time, you'll never go back to the high-heat grilling method again. Get your charcoal lit, grab a cold drink, and let the smoke do the heavy lifting.
