Term (also Décomposition = decomposition) for the sediment that occurs especially in full-bodied, tannin-rich red wines with barrique ageing. It is a completely natural process. The deposit is formed by polymerisation and precipitation of substances (tannins and colouring agents, dead yeast) during bottle ageing. A distinction is made between easily separable solid sediment (dépot fix) and powdery sediment (dépot poudrex). To a certain extent, a deposit is considered a sign of quality, because its appearance indicates the beginning of a wine's drinking maturity. A certain protection against the deposit being whirled up when pouring into the glass is offered by bottle bottoms with an indentation, where the sediment can collect in the groove and is thus less visually noticeable.
The wein.plus encyclopaedia is a comprehensive, well-researched reference work. Available anytime and anywhere, it has become an indispensable part of teaching, used by students and myself alike. Highly recommended!
