Editing Pomace

'''Pomace''' or '''marc''' is a solid byproduct of the [[winemaking]] process. It is derived from the pulp, skins, stems, and seeds of [[grape]]s after the juice has been extracted for wine production. Pomace has been used in various ways throughout history and across cultures, including as a fertilizer, a source of [[biofuel]], and a component in the production of certain types of [[brandy]] and [[grappa]].

== History ==

The use of pomace dates back to ancient times. The [[Romans]] and [[Greeks]] used pomace as a fertilizer, recognizing its rich nutrient content. In more recent times, pomace has been used in the production of [[pomace brandy]], a type of brandy made from the fermented pomace.

== Composition ==

Pomace is composed of the skins, pulp, seeds, and stems of grapes. The exact composition can vary depending on the type of grape and the winemaking process. Generally, pomace is rich in [[fiber]], [[antioxidants]], and [[polyphenols]], which are beneficial compounds found in plants.

== Uses ==

=== Winemaking ===

In winemaking, pomace is often used to produce a second, less expensive wine known as [[pomace wine]] or ''vin de piquette''. This is made by soaking the pomace in water and fermenting it a second time.

=== Distillation ===

Pomace can also be distilled to produce a type of brandy known as pomace brandy or ''marc''. This is a common practice in countries such as [[Italy]], where it is known as ''grappa'', and [[France]], where it is known as ''marc de Bourgogne''.

=== Fertilizer ===

Due to its rich nutrient content, pomace has been used as a fertilizer for centuries. It can be composted and used to enrich soil, promoting plant growth.

=== Biofuel ===

More recently, pomace has been explored as a potential source of biofuel. The high sugar content in the grape skins and pulp can be fermented to produce [[ethanol]], a type of biofuel.
