Whey Cheese

What is Whey Cheese?

Whey cheese is a category of cheese produced from whey, the liquid remaining after milk has been curdled and strained. This distinguishes it from cheeses made primarily from casein curds. Whey cheeses utilize proteins like albumin and globulin that remain dissolved in the whey after initial cheese production.

The scope of whey cheeses includes varieties such as Ricotta, Gjetost, and Mysost. These cheeses are often lower in fat than their curd-based counterparts due to the composition of whey. They represent an efficient use of dairy byproducts, reducing waste in traditional cheesemaking.

Whey Cheese Production

Production begins by heating the leftover whey from cheese production, typically to near-boiling temperatures around 85-90°C. Additional acid or dairy may be introduced to encourage protein coagulation. The heat causes the remaining whey proteins to denature and form fine, delicate curds.

These fragile curds are carefully skimmed from the surface or filtered from the liquid. The resulting cheese may be drained, pressed, or further processed depending on the variety. Some whey cheeses like Gjetost undergo caramelization through prolonged heating and reduction.

Sensory Characteristics

Whey cheeses typically exhibit a mild, slightly sweet flavor profile with subtle dairy notes. Their texture ranges from moist and granular in fresh varieties like Ricotta to firm and sliceable in cooked types like Gjetost. The color varies from pure white to deep caramel brown depending on processing methods.

These cheeses generally have higher lactose content than curd cheeses, contributing to their characteristic sweetness. They lack the sharpness or complexity of aged curd cheeses, instead offering clean, straightforward dairy flavors. The mouthfeel is often light and sometimes slightly grainy.

Culinary Applications

Whey cheeses serve both savory and sweet culinary purposes across various cuisines. Fresh varieties like Ricotta are essential in Italian dishes including lasagna, cannoli, and ravioli fillings. Their mild flavor and creamy texture make them versatile ingredients that don’t overpower other components.

Firmer whey cheeses like Scandinavian Brunost are traditionally sliced thin and served on bread or crackers. They melt smoothly, making them suitable for sauces and baked dishes. Their sweetness pairs well with fruits, making them popular in dessert applications.

Regional Variations

Italy produces several whey cheeses including Ricotta Romana and Ricotta Salata. These vary from fresh, moist cheeses to salted, aged versions suitable for grating. Italian whey cheeses are protected under PDO (Protected Designation of Origin) status in some regions.

Scandinavia specializes in brown whey cheeses like Gjetost and Gudbrandsdalsost from Norway. These are made by slowly caramelizing whey until it thickens and develops a distinctive brown color and sweet flavor. Greek Manouri represents another regional variation, a semi-soft whey cheese often enriched with cream.
