There are a lot of great wines. What I found is that my taste of wine changes through the years, and my favorite wines have varied as my experience grown.
Many years ago, I was a strict Californian Merlot and Cabernet drinker. I am still a huge fan of Californian Merlot and Cab - those huge, in-your-face wine that is big on fruit and big on oak. With the Bordeaux having several good years over the last decade and half, I have grown a love for nice French Bordeaux. Then I discovered Italian, especially the SuperTuscans. My friend then bought a Portland vineyard and start making Pinot Noir, so that becomes a essential ingredient of our regular drinking when we go out for dinner. It took me many years to find a liking of the spicy Syrahs/Shirazs, but since then I have also enjoyed my Cali and Australian Syrahs. Most recently, I have fallen in lover Petit Syrah, which actually is reminiscent of the big Californian Cab. What an interesting circle of interest.
However, through all of these changes, I have fallen in love with a particular winery, Pride. It is a nice boutique winery that makes many varietal of wine, including Viogneir, Chardonnay, Merlot, Cabernet Sauvignon, Cabernet Franc, Meritage/Claret, Syrah, Petit Syrah (sadly no longer in production), Sangiovese, and dessert wine called Mistelle of Viogneir. Their wine making philosophy remains the same - to show off the fruity mountaintop wines from Napa and Sonoma area. The end results are consistantly good wine years after years, not mentioning the ability to cellar and age these wines over the years. I have Merlot for almost 10 years and still drinking great. This is definitely my favorite winery. The Pride wines are hard to find on liquor stores and only limited in availability in fine restaurants, but they are worth every penny - usually $40-60 per bottle from winery and up to $125-150 for reserve wines.
As for other favorite wines, I also like Caymus Conundrum ($20), Revana Cabernet ($110), Joseph Phelps Cabernet ($50) and Syrah ($35), Swanson Merlot ($25), Frank's Family Cab ($45), Chateau Pichon Lougeville ($50-100), La Sirena Muscato Azule ($35), Bonny Doon Vin Gris de Cigares ($15), Heitz Port ($30), Frank's Family Rouge Champagne ($45).
As for you, might I suggest Molly Dooker (mollydookerwines.com), a nice Australian winery that makes good cab and syrah, some at good price (try Boxer, $20) and some more expensive (Goosebump, $50, amazing sprakling pink syrah, wow)
Cheers!
