Dry-Aged Porterhouse 32 Oz


The Snake River Farms American Wagyu porterhouse is a classic steak featuring a flavorful New York strip and a tender filet mignon separated with a T-shaped bone. The porterhouse is dry-aged for 45 days or more.


This cut has something for every steak lover and at two-pounds is large enough to feed two ravenous souls. Our porterhouse is already near perfect with rich, fine marbling and hearty flavor, but we’ve advanced one of our most beloved steaks to delicious new heights with the addition of dry-aging.

Snake River Farms dry-aged beef represents a higher echelon for our American Wagyu steaks. Our partner, Prime Food Distributor, developed a proprietary method with strict protocols and quantifiable performance standards at every stage of the dry-aging process. When our beef is received, it is measured and tagged so it can be tracked electronically from start to finish. Large sub-primal cuts are aged in a meticulously controlled dry-aging environment for a minimum of 45 days. When perfectly aged, our beef is hand cut into generous steaks and shipped fresh to your door using Expedited Shipping. You’ll receive a porterhouse of the highest order with a distinctive buttery aroma and an intense beef flavor unique to our dry-aged steaks.

Beef Grading 101

This steak is American Wagyu Black Grade, rated 6 to 8 on the Japanese Beef Marbling Score (BMS)

Beef sold in the U.S. is graded by the United States Department of Agriculture (USDA). There are eight total grades and the top grade is USDA Prime.

All Snake River Farms American Wagyu beef grades above Prime. Special breeds of cattle like Japanese Wagyu are capable of producing intramuscular fat beyond their American counterparts. To grade this high level of marbling, we adopted the Japanese Beef Marbling Score.

Using BMS, beef marbling is measured on a scale from 1 to 12, with a 1 being Select beef and a 12 being the highest level of marbling possible.

BMS 4 to 5     USDA Prime

BMS 6 to 8     SRF Black Grade

BMS 9+          SRF Gold Grade




The Porterhouse is cut from the short loin, a smaller portion of the loin primal. The larger side of the steak is the longissimus dorsi muscle, the source of the New York strip. A t-shaped bone divides the steak and the smaller side of the steak is the psoas major, a muscle that receives minimal use and is the most tender of all beef cuts.

Fast fact: The Porterhouse and t-bone are both cut from the short loin. A Porterhouse must have a section of tenderloin at least 1.5 inches wide. Any smaller and it’s a t-bone.
