English wine.
British. It's not only from the part of Britain that's England.
I have never seen an English wine in the store.
In Kaufland and Lidl in Germany? Fime if you want a bottle of liebfraumilch for 6 euros....
Most wine from the UK is sold quickly to good restaurants and wine merchants or gets bought and laid down by investors
