One of my very favorite wines is a Casel Garcia from Portugal. It is probably a better summer wine than winter, so my timing is a bit off (but hey - the sun is shining somewhere right?!).
My friend Alex and I used to drink this out on the patio under the sun while grilling up some delicious foods. It is light enough to go with just about everything, and it has a nice effervescence to it - and it is under $10!
The best part of all (for all you suckers like me) is the gorgeous label - it is dark blue with a delicate lace pattern covering it. Two thumbs up from me!
