Looking for a Buy and Hold wine
I'm not a wine drinker at all but my wife loves to drink and taste it. She always talks about getting a case of wine and letting it age for years then drinking it when it peaks. I'm looking for suggestions for wines that I can buy her that will be good/better to drink in 10-20 years.
If they are affordable (whatever that means to you) that is even better.
It's more important, of course, what affordable means to you, since you'll be doing the buying...
As burgundy, bordeaux, and barolo have all been mentioned here, I'll give you a lower-cost option... tempranillo. Look specifically at Reservas from the fabulous 2001 vintage in Rioja and Ribera del Duero... Many reserva bottlings from the also-great 2004 vintage have yet to be released but are also great candidates for your objective. These wines will mature and evolve for 15+ years and are still priced in the $20's per bottle in many instances.
In white wines I'd go a bit out on a limb and suggest that with good cellaring you're going to get remarkable evolution from the 2005 riesling vintage in the Mosel region of Germany, and again, these wines are very reasonably priced, many great bottles are in the teens or low 20's.
Lastly, since you've "saved" on the red and white cases, add a couple bottles of dessert wines.... the 2000 and 2003 Vintage Ports are excellent, with good bottles well under $100....
Ditto the incredible 2001 Vintage in Sauternes with great bottles still available under $70 and the 2003 vintage available under $50.
That's my "affordable" cellaring plan: Case of 2001 Rioja Reserva, Case of 2005 Mosel riesling, one bottle of Vintage Port and one bottle of Sauternes....
Cellar them well, and enjoy in about 10 to 15 years :)
I have to agree with Mengathon, esp insofar as Burgundy is concerned. Most Burgundies that I would age, that used to cost $50-$150 bottle, in '05 cost $100-$500.
Look to the Northern Rhone -- specifically Hermitage. Not cheap, but a $70 Hermitage can age effortlessly for 10-20 years and provides a much better value than Burgundy. I'm nto a huge Bordeaux fan to begin with, but there are some good values to be had there, as well. I'd look to 2001 Montrose for around $50 and 2005 Montrose for about $100.
If white wine is an option, there are SOOOO many great German whites at the Auslese level for under $50/bottle...
There's a million possible answers to this question, as you may have guessed. All the previous posters have really great suggestions.
If your wife prefers white wines, you could also go for a 2005 Savennieres from the Loire Valley (Closel is a good producer), or a 2004 white burgundy.
For reds, you could also go Italian and get a case of 2004 Barolo -- these will definitely get better with age. Or you could go Spanish and get some 2004 Rioja, another great wine that ages well.
These wines won't be cheap, but the prices aren't as sky-high as the much-sought-after 2005 red bordeaux and burgundy wines.
I'd recommend staying away from California, New Zealand, or Australian wines -- you'll have better luck finding age-worthy wines in France, Italy and Spain.
The '05 Bordeaux and Burgundies have gotten great reviews, but they just seem far over-priced. On the other hand, a lot of the '05 Rhônes should age just as well and be a lot more palatable to your wallet.
But for my money, I'd go and buy a couple of cases of the 2005 Domaine des Baumard Coteaux du Layon, Clos de Ste Catherine, around $45-50. It's a sweet chenin blanc from the Loire Valley. I had one recently on another hound's rec, and immediately went out and bought another half case. I've never had such a complex white. It's half as expensive as Sauternes, and a good bet to last a couple of decades.
2005 bordeaux. Great year, and they are classic hold'em wines. Because the vintage is so strong, you can buy more reasonable wines ($20-30 price range). The less expensive wines are drinkable now. We had a Chateau Moulin de Curat 2005 Saint-Emilion the other day (about $21 Canadian). It had loads of fruit and a tight tannin backbone which was present but still smooth enough to drink now. So it is fun to drink it now, and then follow it as it ages. Because of the tannins, I think this wine will age well, and for the price it was a real winner. I haven't had a chance to explore this vintage significantly, but I plan to as the wines get released. I think there will be some great age-worthy wines at prices that regular humans can afford, and with the quality of this vintage, they will be relatively easy to hunt out! And they go so well with lamb....
Now if you want high end, well, just go to any good wine store, open your wallet and go to town...
