Wine produced by ecological methods produces relatively little nasal blockage in wine-sensitive subjects.
CONCLUSIONS
Subjects with self-reported nasal symptoms following consumption of red wine may respond with less nasal blockage to a wine produced with ecological methods than to wine not labelled as ecologically produced.


OBJECTIVE
To compare nasal symptoms following intake of three different wines--one that was ecologically produced and two that were traditionally produced.


METHODS
Individuals with self-reported nasal symptoms following consumption of red wine were subjected to controlled intake of three different wines in a double-blinded, randomized, and crossover design. Nasal symptoms and peak nasal inspiratory flow (PNIF) were monitored before and 15, 30, 45, and 60 min following intake of wine.


RESULTS
All wines produced nasal symptoms, notably nasal blockage. While blockage scores did not differ between the two non-ecological wines, the ecological wine was associated with significantly lower blockage scores, as compared with both the other wines.
