I think everyone gets the drift though. Apart from Keith....

You did not Dave.
You posted,
"Well, post brexit when said vino is subject to import tariffs I suspect our little trattoria will find Calafornian Zinfandel at 10p a bucket will make better financial sense"

You clearly had no idea what difference taiffs make to wine.
Californian and other non-EU wines would only be 10p a bottle cheaper if tariffs were removed, and EU wines only 10p dearer if tariffs were applied.

I am constantly astonished that you people can have such strong opinions on something you know nothing about.
