Orange wine, also known asskin-contact white wine,skin-fermented white wine, oramber wine,[1] is a type ofwine made fromwhite wine grapes where the grape skins are not removed but stay in contact with the juice for days or even months, as is more typical with red wines.[2] This contrasts with conventional white wine production, which involves crushing the grapes and quickly moving the juice off the skins into thefermentation vessel. The skins containcolor pigment,phenols andtannins that would normally be considered undesirable for white wines, while for red wines skin contact andmaceration is a vital part of the winemaking process that gives red wine its color, flavor, and texture.[3] Orange wines tend to benatural (a.k.a. minimal intervention) wines.
TheInternational Organisation of Vine and Wine describes orange/amber wine as "White wine with maceration" and prescribes the minimum duration of the maceration phase to be 1 month. In theUSA,Marlo Anderson, founder of the registered trademark “National Day Calendar”, has deemed the 6th of October to be National Orange Wine Day.[4]
The practice has a long history in winemaking dating back hundreds of years inSlovenia andFriuli-Venezia Giulia,[5] and thousands of years in the Eastern European wine producing country ofGeorgia.[6] The practice was repopularized by Italian and Slovenian winemakers, after visiting Georgia and importingqvevris, initially in the cross-borderFriuli-Venezia Giulia wine andGorizia Hills regions,[7] while there is also production in Spain,Slovenia,Croatia,Slovakia,Austria,Germany,New Zealand, andCalifornia.[8][9]
Skin-fermented white wines were common in Italy up until the 1950s and 1960s, but fell out of fashion when technically 'correct' and fresh white wines came to dominate the market.[10]
The popular termorange wine was coined by a British wine importer, David A. Harvey, in 2004.[11] This style of wines can also be known by their color 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.[12][13]
In Georgia, skin-contact white wine is known as “karvisperi ghvino", which translates asamber wine. This term was introduced bySandro Shanshiashvili in his 1920 poem "Wine".[14]
The basic differences of orange wine with the other wine 'colors' are based on the color of the grape and the duration of their skin contact.
| Long contact with grape skins | Short contact with grape skins | No contact with grape skins | |
|---|---|---|---|
| Red grapes | red wine | rosé | white wine |
| White grapes | orange wine | ||
Red wine is made with red grapes. After the red grapes are crushed, their skins stay in contact for a period of 1 week to 1 month, and the wine gets a red or deep red color. Rosé, at least when rosé wine is the primary product, is produced with the skin contact method, using red grapes. After the grapes are crushed, their skins only stay in contact a few hours before pressing, but in that short period they give the wine the characteristic light pink hue.
White wine is made either with red or white grapes. The grapes are pressed and their skins are removed immediately. Because the grape skins do not "participate" in the fermentation, their color does not matter and the wine acquires a neutral, green to slightly yellow hue. Orange wine is made with white grapes. After they are crushed, their skins stay in contact for 1 month to 6 months, and the wine acquires an amber, orange color.
