 "Crème" in this case refers to the consistency.
 This category includes crème de cacao (chocolate), crème de menthe (mint), crème de mûre (blackberry), and crème de cassis (black currant).

Skin-contact wine, amber wine, or orange wine is a type of wine made from white wine grapes where the grape skins are not removed, and stay in contact with the juice for days or even months.
 This contrasts with conventional white wine production, which involves crushing the grapes and quickly moving the juice off the skins into the fermentation vessel.
 The skins contain color pigment, phenols and tannins that would normally be considered undesirable for white wines, while for red wines skin contact and maceration is a vital part of the winemaking process that gives red wine its color, flavor, and texture.
 This style of wines can also be known by their colour references of having an amber or orange tinge that the base white wine receives due to its contact with the coloring pigments of the grape skins.
