Sub-Zero has just announced a new line, its "Built In Refrigeration Series," which will keep food fresher longer, effectively reducing food waste. Between its unique dual-compressor system, advanced air purification and water filtration system, this refrigerator is a work of science. For those of us who don't quite understand how aforementioned systems work, there's also a "freshness guide" inside the unit to tell us where best to store fruits versus leftovers.

The line will be available in Fall 08. Check out the gallery to see some of your options!

While the phrase "Enter to win!" is often accompanied by eyerolling and a lesson in probability, when it comes to the 2008 Sub-Zero Dream Kitchen -- and dreamy it is, complete with sleek sub-zero fridge, freeze and wine storage alongside $2,000 worth of gourmet goodies from Dean & Deluca, Wolf dual range, Kohler kitchen gear ... the list goes on -- the words just may inspire a foodie frenzy. Until July 31, enter here if you aspire to cook and entertain in this kitchen-for-the-gods (did we mention ambrosia flows freely from those Kohler products? And there is a subscription to the Windsor Sonoma Wine Club?). Winners of the $50,000 in kitchen booty will be notified August 3. I hope I'm invited to your first dinner party.

New York's Core Development Group previewed Lux 74, its newest high-end development the other night. The "Full Service Luxury Residence" at 429 East 74th Street will be ready for occupancy this summer; there are only 12 units in the building, ranging from studios to five bedrooms, priced at $685,000 to $8.2 million. With a focus on modern design, the fully-finished units feature Viking, Sub-Zero and Miele appliances, hand mitered Giallo Elena limestone counter tops, Italian Stone and mosaic accents, walnut paneling, Lava stone clad fireplaces, thermostatically controlled radiant floor heating in all bathrooms, oversized air jet bath tubs, three fixture laundry rooms, and Panasonic plasma TVs and Bose hi-def surround sound A/V systems. Many also include private outdoor space, and the building boasts a 24-hour concierge to cater to residents' every whim. See the gallery for more.

Sub-Zero recently announced an overhaul of its line of built-in models, to be available this fall. What's especially interesting and appealing is that all the air in the line's models will be "scrubbed" by a purification system an average of once every 20 minutes to eliminate odors, viruses and bacteria that can lead to hastened ripening and, ultimately, spoilage. Additionally, the products offer something Sub-Zero states no refrigerator ever has -- a water filter that reduces viruses and bacteria, in theory reducing contaminants while keeping water and ice tasting fresh.

Other new features: brighter lighting, crisper drawers that have an improved glide system, an easy-to-use digital control panel and adjustable door shelves that can be moved in one-inch increments. The exterior can be customized, too, using one of these options:

• Flush Inset: Flush with surrounding cabinetry. Has a smaller profile and facilitates inset installation. Available in Classic Stainless, Platinum Stainless or Carbon Stainless Steel panels, or can be fitted with custom panels.
• Stainless Steel: Finished in Classic Stainless Steel, ready out-of-the-box. Works with any commercial-style kitchen. Redesigned with a new ventilation grille.
• Framed: Consumer may slide a custom cabinetry panel into an existing frame so that the door better matches the kitchen. Has a new extruded handle and redesigned louvered grilles.
• Overlay: Consumer may incorporate cabinet panels and custom handles into the doors and grille.

I have a Sub-Zero integrated model (similar to the model in the photo, a current Sub-Zero product) with an overlay that blends in so well that when the real estate agent was showing me the kitchen, I had to ask her where the refrigerator was. But buyer beware -- a Sub-Zero costs quite a lot, and definitely delivers on its promises, but can be expensive to repair. I learned this the hard way last year when my motor burned out because I hadn't "serviced" the system. Who knew a refrigerator required a yearly tune-up? It seems I have the Mercedes of refrigerators -- lovely to look at, performs like a dream, but even a simple oil change can set you back $300 (or, in my case, $1,000 for a new motor and yearly servicing).

Those who buy Sub-Zero appliances likely can afford any repair work on them, but why waste money? If you get one of these new models, be sure to ask the sales rep about yearly service.
