Is drinking a glass of red wine a day healthy?
For most commercially available wine, the answer is no.
Surprisingly, the reason has nothing to do with unhealthy additives.
It's about what gets taken out.
The health case for red wine is built entirely on polyphenols.
Polyphenols are antioxidants that reduce chronic inflammation and feed the gut bacteria tied to immune function.
Red wine has significantly more polyphenols than white because they concentrate in grape skins and seeds, which stay in contact with the juice throughout red wine fermentation.
Their volume is high in all red wine, but their bioavailability is a different story.
Polyphenols need the proteins, peptides, and colloids that naturally occur in wine to slow gut transit long enough for your microbiome to convert them into something absorbable.
In nearly all commercial wine, those proteins, peptides, and colloids that your body needs to process polyphenols have been filtered out.
The polyphenols are still in the wine. Your body just doesn't absorb them anymore.
If the wine doesn't explicitly say unfiltered, it has been filtered.
Peony lane wine is unfiltered.
