Thx that's a very extensive explanation.

I'm a red wine fan, when I do drink white, I get a headache.

In France only a few vineyards refrain from adding sulphites to red, which, as rightly point out, should not always be necessary thx to tanins who also have an anti-oxidant action.

In Europe over la last 30 years, there has been a trend away from quantity and towards better quality. That's why I steer away from too cheap wines in order to reward those who make an effort in improving their product.
