Cream produced by cows (particularly Jersey cattle) grazing on natural pasture often contains some natural carotenoid pigments derived from the plants they eat; this gives the cream a slight yellow tone, hence the name of the yellowish-white colour cream. Cream from cows fed indoors, on grain or grain-based pellets, is white.

Types of cream
In the United States, cream is usually sold as:

• Half and half (10.5–18% fat)
• Light, coffee, or table cream (18–30% fat)
• Medium cream (25% fat)
• Whipping or light whipping cream (30–36% fat)
• Heavy whipping cream (36% or more)
• Extra-heavy or manufacturer's cream (38–40% or more), generally not available at retail.

Not all grades are defined by all jurisdictions, and the exact fat content ranges vary. The above figures are based on the Code of Federal Regulations, Title 21, Part 131 and a small sample of state regulations.

In the United Kingdom, the types of cream are legally defined as follows:

Other cream products
Sour cream in the U.S. is cream (18% or more milk fat) that has been subjected to a bacterial culture that produces lactic acid (0.5%+), which sours and thickens it.

Crème fraîche is a heavy cream slightly soured with bacterial culture, but not as sour or as thick as American sour cream. Mexican crema (or cream espesa) is similar to crème fraîche. Smetana is a Central and Eastern European sour cream.

In the UK, clotted cream (similar to Indian malai) is a very high-fat (55%) product processed with heat.

Butter is made by churning cream.

Whipped cream

Whipped cream may be sold ready-to-use in pressurized containers. Nitrous oxide is used as a propellant, and when the cream leaves the nozzle, it produces four times the volume of whipped cream, i.e., twice the volume produced by whipping air into it. Using this technique, it may also be prepared in reusable dispensers, similar to a seltzer siphon bottle, using inexpensive disposable nitrous oxide cartridges.

Chantilly cream (French: crème Chantilly) is whipped cream with sugar and vanilla.

Cream as an ingredient
Cream is used as an ingredient in many foods, including ice cream, many sauces, soups, and some custard bases, and also uses for cakes.

In the United States of America, cream (usually light cream or half-and-half) is often added to coffee.

Other foods called cream
Some foods or even cosmetics may be labelled cream but not because they are made with cream, but because they make claim to the consistency or richness of cream. In some locations labelling restrictions prevent the use of cream so variations such as creme, kreme, creame, or whipped topping may be found.
