Fat cap forms from subcutaneous fat deposits. Its thickness affects cooking (protection and basting), while its color and texture indicate diet and freshness. White, firm fat suggests grain-fed; yellowish fat often indicates grass-fed or age.

Fat Cap Analysis FAQs
Common questions about fat cap analysis
For smoking, 1/4 to 1/2 inch fat cap is ideal. It protects the meat during the long cook while rendering to baste the meat. Thicker caps can be trimmed. Less than 1/4 inch may leave the meat vulnerable to drying.
Yellow fat often indicates grass-fed cattle (beta-carotene from grass) or older animals. It's not a quality defect - many consider it more flavorful. Pure white fat typically indicates grain-fed cattle.
It depends on the cooking method. For smoking/roasting, leave 1/4 inch for protection. For grilling steaks, excessive fat can cause flare-ups. Render the trimmed fat for cooking if you like.
