wines and ratings

Here's a wine list and some of my ratings. The scale is from 0 to 10. Bitterness is in an inverse scale: the higher the number the less bitter it is (the better).

Little Penguin Merlot Australian bitterness: 8 rating: 9
Sangloves di Tusdano, Dievole bitterness: 7 rating: 7
Peller Cabernet Sauvignon bitterness: 7 rating: 8
Chardonnay Brancott Classic bitterness: 8 rating: 9
Serras de Azeitão Merlot bitterness: 8 rating: 9

Redwood Creek Merlot bitterness: 8 rating: 8
Copper Merlot bitterness: 8 rating: 8
... Shiraz bitterness: 8 rating: 8
Pinot Grigio bitterness: 7 rating: 6
Cabernet Merlot Australian bitterness: 8 rating: 5

I couldn't find a reference to this Copper Merlot anywhere. It's too soon to draw conclusions. I need a larger database! Who knows - perhaps later on I can create an ontology to classify the wines.
