Why Brisket Is Sliced Against the Grain

A brisket can spend all day over a post oak fire and still be harder to chew if it’s sliced the wrong way. The cook hasn’t changed. Neither have the seasoning, bark, or smoke. The only difference is the direction the knife traveled through the meat.

That may sound like a small detail after hours on the pit, but it changes the length of the muscle fibers left in every slice. Those fibers have a lot to do with how tender the brisket feels when you take a bite.

Grain Is Easier to See Than It Sounds

The grain is simply the direction in which the muscle fibers run. Look closely at an unsliced piece of beef, and you can usually see faint lines traveling across its surface.

Those lines are bundles of muscle fibers. When you slice in the same direction they’re running, many of those fibers remain long. Your teeth then have to pull through them as you chew. Cut across the grain, and the knife shortens the fibers before the brisket reaches your plate.

That is why slicing against the grain makes brisket easier to bite through. It doesn’t add moisture or change the cook. It changes how much work is left for you to do at the table.

Cooking Can’t Do All the Work

Hours of slow smoking give the connective tissue inside a brisket time to soften. That process is a major part of turning a tough cut of beef into tender BBQ, but it doesn’t make the direction of the muscle fibers disappear.

You can see the difference when you gently pull on a properly sliced piece. It should hold its shape on the plate but separate without much effort. Leave the fibers too long, and the same brisket can feel stringy or chewy even when it came off the pit at the right time.

Slicing can’t rescue an undercooked brisket, either. The pit and the knife have separate jobs. A good cook softens the meat, and a good slice makes that tenderness easier to enjoy.

One Brisket Has Two Different Grains

A whole brisket contains two overlapping muscles: the leaner flat and the fattier point. A seam of fat runs between them, and the muscle fibers do not travel in the same direction through both.

That is where brisket becomes more complicated than a smaller cut such as flank steak. A pitmaster can begin slicing the flat correctly and eventually reach the point, where the grain runs at a different angle. If the knife keeps moving in the same direction, those later slices may be cut with the grain.

This doesn’t mean the point was smoked differently or suddenly became tough. It means the fibers left in each slice are longer.

Our existing guide, How to Slice Brisket Without Messing It Up, shows Barrett Black identifying that change and adjusting his knife for the second muscle.

Slice Thickness Changes the Bite, Too

Direction isn’t the only decision being made at the cutting board. Thickness matters because the point and flat don’t have the same texture.

The flat is leaner and firmer, so it is generally sliced thinner. The point carries more fat and has a softer texture after a long cook. The slices can be cut a little thicker while still being easy to eat.

No single measurement works for every brisket. Pitmasters pay attention to how the meat feels as the knife moves through it. If a slice falls apart before it reaches the tray, it may be too thin for that particular section. If it takes too much effort to pull apart, a thinner slice may eat better.

The Knife Gets the Last Word

Most of the work happens before a brisket ever reaches the cutting board. The beef has to be selected, trimmed, seasoned, smoked, and rested. Slicing is the final step, but it determines the length of the fibers in every bite served.

That’s why pitmasters pay attention to the grain even after spending hours watching the fire. Cutting across it lets the tenderness created on the pit come through instead of leaving long fibers for the customer to chew.

At Black’s BBQ, our pitmasters handle that last step before the brisket reaches your tray. Come taste it at our locations in Lockhart, Austin, New Braunfels, or San Marcos.
