Within the Catholic Church and traverse many international borders mulled wine is a favourite drink in many a Catholic homes on the Feast of the Apostle St. John (December 27).
Of Course mulled wine is a very popular tradition on this day and throughout the Christmas season.
St. John the Apostle, is the disciple "whom Jesus loved". It is a custom in the old countries to drink of "St. John's Love". The Church provided a special blessing of wine in honour of the Saint. According to legend St. John drank a glass of poisoned wine without suffering harm because he had blessed it before he drank. The wine is also a symbol of the great love of Christ that filled St. John's heart with loyalty, courage and enthusiasm for his Master; he alone of all the apostles was not afraid to stay close to Our Lord during the Passion and Crucifixion. - St. John's Wine
Nowadays the faithful drink mulled wine (Glühwein) on the Feast of St. John. Many different cultures still take part in this tradition.
This hot mulled wine can be served on St. John's feast day. On St. John's Day, the Roman Ritual tells us that "wine offered by the faithful is blessed in remembrance and in honour of St. John who without any ill effects drank a cup of poisoned wine." It was by faith that St. John was saved, and through the mystical union became the disciple whom the Lord loved best. By love and faith man comes to God. We, too, pray as members of the mystical body. - St. John's Wine
Then there is the Nordic Glögg mulled wine tradition which is served on St. Lucy's Day (December 13) in Sweden.
Glögg, gløgg, glögi and similar words are the terms used for mulled wine in the Nordic countries.
In Sweden, ginger bread and lussebullar (also called lussekatter), a type of sweet bun with saffron and raisins, are typically served on December 13 to celebrate Saint Lucia's Day. It is also traditionally served at the julbord, the Christmas version of the classic, Swedish buffet smörgåsbord. In Denmark, gløgg pairings typically include æbleskiver sprinkled with powdered sugar and accompanied with strawberry marmalade. In Norway, gløgg is paired with rice pudding (Norwegian: riskrem). In such cases, the word graut-/grøtfest is more precise, taking the name from the rice pudding which is served as a course. Typically, gløgg is drunk before eating the rice pudding, which is often served with cold, red cordial (saus). - Mulled Wine (Wikipedia)
Many European countries including Germany celebrate Silvesterabend (New Yerar's Eve) with mulled wine.
Austria, and its neighbour to the north, Germany, call New Year's Eve Silvesterabend, or the eve of Saint Sylvester. Austrian revelers drink a red wine punch with cinnamon and spices, eat suckling pig for dinner and decorate the table with little pigs made of marzipan, called Marzipanschwein. New Year's food traditions around the world
The last day of the year is called "Sylvester" in Europe. This word is derived from the liturgical feast, celebrated on December 31, of St. Sylvester, pope and confessor, who died in the fourth century.
The end of the old and the beginning of the new year was, and still is, observed with popular devotional exercises. Special services are held in many churches on New Year's Eve to thank God for all His favours in the past year and to implore His blessings for the new one.
A distinctive feature of the traditional celebration is the feasting and merrymaking during the night, often combined with masquerades, singing, and noisemaking. This is a relic of the pre-Christian reveling in ancient Rome; its original significance was to salute the New Year and to drive the demons away.
The main item of Sylvester drinking is the punch bowl. Today we have quite a variety of punches. The modern form of punch originated in England in the early seventeenth century. It consists of alcohol, water, spice, sugar, fruit essence. The word seems to be an abbreviation of "puncheon," which was the name of the cask from which grog used to be served on English ships. - Mulled Wine
