Cream sherry is a fortified wine that has been artificially sweetened by blending in sweet wine. While cream sherry originated in Spain, the term is now a generic one, as cream sherries are now produced in the US and other countries.
In Spain a cream sherry is also known as Dulce; it is often made by taking a dry Oloroso wine and blending in Pedro Ximénez or Moscatel wines.
The style originated with Harvey's Bristol Cream, which was quite popular some thirty years ago. Today cream sherries have lost a good deal of sales in the market, as consumers are looking for drier products.
Cream sherries tend to pair well with vanilla ice cream, pastries or as an after-dinner drink.
