It is a Grenache.

 

Did you have a feeling it might be a Grenache or were you completely off with your guess?

Now you know it is a Grenache, why not try the wine again and see what characteristics you might be able to pick up, which hint towards it being this grape. Or is it such an unusual Grenache, that you can't find any "typical" features?

So, to summarise:

This is a Spanish Grenache.

It comes from a region called Castilla y Leon.

The only thing left to find out is...

Who could be the producer of this wine?
