As you already noticed, our collection is mostly red wines. We have been collecting for over 20 years.
I will preface our "favorites" with..."you might not know or be able to find these in stores near you"...
That said, we are partial to:
Paloma
Pahlmeyer
Ridge
Williams Selyem
Flowers
Bouchaine
Tom Eddy
Araujo
Rafanelli
Galleron
Karl Lawrence
Pride Mountain Vineyards
Shafer
Turley
Kapscandy
to name a few

And that's just the US wines. I also collected many French wines while living in France, but haven't kept up with the French wines since moving home about 7 years ago...
