Temecula Wineries

I've never been and was wondering if anyone has any recommendations for which wineries are best in Temecula?  I see a bunch of deals on groupon but not sure if those are the best choices.  Thanks!

...I go there for the baked cheese bread.

Wiens winery, they have family wineries at Laguna and Newport.  Grab some food at the grocer half a mile from them and do a tasting at their winery.  Tables outside for food.  Usually not crowded because it's not on the groupon/living social winery tours.  Big reds are what they're known for.  Wilson Creek down the road is more commercial, but plenty of seating and they are known for sweeter wines.

I ended up checking out Wein, Wilson Creek and Miramonte.

Wein was nice and chill while they others were pretty busy.  Miramonte I had the nicest outdoor patio on a hill.
