Black radish extract may replace sulphur dioxide for wine: study

An extract of black radish (Raphanus niger) may provide a natural alternative to sulphur dioxide for viticulturists, according to a new study from Greece.

this last part is where the problem is ...taste...bottom line... also when SO 2 was used alone you got more anthocyanin...this seem like it's great at first glance , but take a good look and you smell @rap...

Wines produced from four different red vinifications using the black radish extract with or without sulphur dioxide. Results showed that “commercially acceptable red wines were produced” in all cases, said the researchers.

The anthocyanin content of the wines was not affected by the use of the black radish extract or the sulphur dioxide, but a higher total and individual anthocyanin content was observed when sulphur dioxide was used alone.

The same was observed for the total phenol and flavanol content of the wine. Despite such observable differences, the wines were still considered to be within in the “range expected for commercially acceptable red wines”, said the researchers.
