Mr. Wine Pimp here ......
I'm not a big Chardonnay fan but I did try one over the weekend that I had to buy 4 bottles of, Windy Oaks. A small winery in the Santa Cruz Mountains, this Chad is more Burgundian in style than most, it was a big hit at the tasting event. Unfortunately it is very limited production and they are down to their last few cases from what I understand. I also prefer my Chardonnay's aged, at 7-10 years you begin to get some very interesting character to it, but you do need to start with a Chard that has ageing potential.
I'm a huge Zin fan, one of my favorite varietals when done right. For your larger producers of QPR Zinfandels check out Bogle, Rosenblum Cellars, Michael David (7 Deadly Zins), Bonny Doon, Cline and Dancing Bull, De Loach and Quivira, Renwood. I generally stick with smaller producers but those are some pretty nice Zin producers, we served the
7 Deadly Zins at a festival last year and it was a huge hit!
There are so many good Syrah/Shiraz out there and I am a snob where those are concerned, buying mostly from small CA producers. Our Syrah, Eno Wines, produces an outstanding CA style Syrah which you can purchase from the website. Other than that, there are so many large producers of quality Shiraz/Syrah that you shouldn't have a problem finding a good one.
Hope this helps!
