Timmermans Oude Gueuzes special flavour derives from its time-honoured method of preparation. It is a blend of old lambic, which has been aged for three years in wooden barrels, and young lambic which ensures spontaneous fermentation in the bottle. The different lambics are carefully selected by the brewer to obtain a perfect flavour. After it has been produced, Timmermans Oude Gueuze, which is refermented for four months in the bottle, continues to improve for 20 years.
