Liquid
Beef stock sold in liquid form, either in cartons or bottles, is ready to use and often found in the soup aisle.
Powdered
Dehydrated beef stock in powder form that can be reconstituted with water to make a liquid stock.
Gelatinous
Some high-quality beef stocks are refrigerated and have a gelatinous consistency due to the collagen extracted from bones during the cooking process.
Concentrated
Concentrated beef stock, such as bouillon cubes or paste, which can be diluted with water to create stock.

Deglazing: Beef stock is often used to deglaze pans after searing meat. The liquid helps lift the fond (browned bits) from the bottom of the pan, incorporating those flavors into sauces or gravies.
Reduction: Reducing beef stock concentrates its flavors, making it an ideal base for sauces like demi-glace. The reduction process involves simmering the stock until the desired concentration is reached, intensifying both the taste and texture.
Simmering: The primary technique for making beef stock is simmering roasted beef bones, vegetables, and aromatics in water for several hours. This slow cooking process allows the flavors to meld and the gelatin from the bones to dissolve, creating a rich, full-bodied stock.
