30 Second Wine Tasting Tip:
"Cooking" wine: An experiment

Pushed-out cork It's a summer morning, and you stop by the wine shop on your way to work to pick up something for dinner. Carelessly, you leave a bottle locked in your car in an open parking lot. The blazing sun beats down all day, and when you come back in late afternoon, the steering wheel and seat covers are too hot to touch ... and the cork in your wine has pushed up through its protective capsule, filling the overheated space with the ripe, grapey aroma of "cooked" wine.

Is your wine ruined?

The conventional wisdom says so. Every wine expert will tell you that even brief exposure to extreme heat will destroy wine; and it seems obvious that heat sufficient to push out the cork can't be good for the nectar in the bottle.

But what exactly does happen? A note from reader Vance Gregory, an Oklahoma wine-shop proprietor, challenged me to find out.

To put it to the test, I purchased two identical bottles of Louis M. Martini 1998 California Cabernet Sauvignon, choosing this wine for the experiment partly because it is a sentimental favorite - Martini was one of the first wineries I ever visited, and I admire them for making quality wines at reasonable prices - and partly because I expected it to be a robust wine, capable of standing up to careless handling.

Then I waited for the next heat wave ... and in the Ohio Valley in June, it wasn't long coming: Highs in the lower 90s (33C) were forecast last Wednesday. At 9 a.m., I put one of the bottles in a bag, taped an oven thermometer to its side, and placed it on the front seat of my car parked in direct sunlight. Eight hours later, with the temperature outside reading 92 and the reading inside the car a toasty 120F (49C), I retrieved the bottle. It was hot to the touch, and the cork had pushed out approximately 1/2 inch (13mm), ripping the top of the capsule and shoving it aside.

I let the bottle cool, then pushed the cork back in and, a day or two later, served both bottles with dinner. (To make the test fair, I marked the heated bottle with a cryptic symbol, then asked my wife to pour them out of my sight, so neither of us knew which bottle had received the heat treatment.)

The results were, well, interesting. The differences between the wines were obvious, but neither was spoiled. The un-heated wine (described in detail in the tasting note below), was ripe, slightly tannic, rather simple, but showed the fruit, balance and structure to suggest aging potential. The heated wine seemed muted at first, but developed with a little air into something surprisingly like a more mature Cabernet; not so tannic but showing subtle, earthy nuances that made it more complex than its gently handled sibling.

This might suggest that a collector who wanted to enjoy aged wines quickly could short-cut the process by heating, a process not unlike that used to make Madeira. Frankly, I wouldn't recommend that! No matter how one isolated experiment comes out, it simply makes sense to take care of your wine and keep it cool ... and that goes double if you're talking about an expensive, ageworthy wine that you intend to keep for a long time. At the same time, the reassuring lesson is that, even if you make a mistake and let your wine get overheated, you needn't assume that it's ruined and can't still be enjoyed in the short term.

30 Second Tasting Notes:
Excellent Value Cabernet
Louis M. Martini Louis M. Martini 1998 California Cabernet Sauvignon ($9.99)
This wine (not the bottle that was deliberately mishandled) is a clear garnet color, with ripe, appealing Cabernet aromas - blackcurrant and cedar - and juicy black-fruit flavors over a good acidic structure and soft but perceptible tannins. It gains richness and complexity over a couple of hours in the glass, hinting at the surprising ageworthiness that has long been typical of Martini's Cabernets. (June 14, 2001)

FOOD MATCH: Works quite well with a simple dish of chicken thighs fricaseed with onions and served with a light sauce of yogurt with black olives.

Wine Tasting 101:
A reminder
If you haven't yet joined in the fun at WINE TASTING 101, the new Wine Lovers' Page feature that we announced last week, I hope you'll take a look.

Dedicated to sharpening your wine-tasting palate by learning to record your impressions and share them with others, WINE TASTING 101 is an interactive online forum in which participants will try the same wine (a new one will be featured each month), then post a tasting report for comment and encouragement in a civil, supportive atmosphere.

This month's wine is PAUL JABOULET AINE 1998 "PARALLELE '45'" COTES-DU-RHONE, a modest French red that should be available in most parts of the world for $10 or less.

I hope you'll click to for the details.
