I wonder where these two come from?

Retailers all around the world have wines labelled for them. They make up brand names or simply use their own name. Which means the same wine could conceivably be on the market under many different labels. In the UK they've gone one step further:No brand and no indication of who it was made for.
But there is absolutely no mistaking their country of origin.
The Pinotage is unmistakeably South African with that earthy feral character displayed by this hybrid variety. If you like your reds squeaky clean this is to be avoided. Otherwise I recommend a try. It has a bit of grunt at 14% a/v and at just £3.89 at Lidl scores 4/5 from me
The Pinot Grigio has a little more palate weight than usual and a dash of sweetness. It's not particularly exciting but I could see it being a real crowd pleaser. £4 at Tesco scores 3.5/5 from me
