St Martin's Day is celebrated all over Europe and through South America. The tradition is that it is a feasting time, before the fast for 'Advent' and marks the end of harvesting time and the start of winter.
In Portugal, Sao Martinho's Day is associated with the maturation of the season's wine and the first day of tasting the new wine. It is commonly marked by roasting chestnuts and drinking 'Jeropiga'.
Personally I do not like Chestnuts but might partake of a glass of 'Jeropiga' in honour of Sao Martinho.
