DeLonghi DEWC46D Dual-Zone Wine Fridge Review
Reviewed by a winemaker. Owned since 2015. Still in daily use.
I bought the DeLonghi DEWC46D in 2015 for NZ$999. The context matters: I was living in a small Auckland apartment with a large Liebherr GrandCru compressor cabinet at my parents' place in Queensland for serious long-term maturation, and I needed something compact for the apartment — somewhere to keep whites, rosé, and sparkling at serving temperature, and a small stash of reds at cellar temperature without occupying kitchen fridge space.
What I didn't fully appreciate when I bought it was that the DEWC46D is a proper dual-zone compressor wine cabinet — not a basic thermoelectric drinks cooler. Ten years of daily use later, that distinction has mattered more than I expected.

Quick verdict
| Who it's for | Anyone needing a compact dual-zone wine cabinet — apartment, kitchen, under bench |
| Who it's not for | Large collections; serious long-term maturation above 50 bottles |
| Biggest strength | Genuine dual-zone compressor performance in a compact underbench format |
| Biggest weakness | Fiddly temperature controls; display reliability after 9–10 years |
| After 10 years | Still cooling. Solid value for what it is. |
Why I bought the DeLonghi DEWC46D
Living in a small apartment changes the wine storage calculus. A large freestanding cabinet was out of the question on space grounds. What I needed was a compact underbench unit with two independent temperature zones — one for whites and sparkling at serving temperature, one for reds at cellar temperature — that could sit in the living space without dominating it.
The dual-zone compressor format was the right answer for this. A compressor unit maintains temperature precisely regardless of ambient conditions. A single-zone unit would have forced me to choose between serving and cellaring temperatures. The DEWC46D solved both problems in a 575mm-wide footprint.

Temperature performance
The DEWC46D's 5–22°C range per zone is genuinely wide for a unit at this price point. In practice I run the upper zone at around 8–10°C for whites and sparkling, and the lower zone at 12–14°C for reds. Both zones hold their temperatures consistently — the compressor-based cooling maintains precision in a way that cheaper thermoelectric units at similar price points cannot.
The controls, however, are a genuine frustration. The touch-sensitive buttons require patience to set precisely — small adjustments take several presses and the interface is not intuitive. I set both zones to target temperatures early on, confirmed they were holding correctly, and have not adjusted them since. For most users that's a practical workaround, but it shouldn't be necessary on a unit at this price.
The climate class T advantage — more useful than I realised
Climate class T means the DEWC46D is rated to operate in ambient temperatures up to 43°C. Most underbench wine cabinets carry a climate class of ST (up to 38°C) or lower. I didn't specifically buy it for this capability, but it has proved its worth.
The unit has since moved from the Auckland apartment to a below-stairs garage at our current home. The garage is semi-below-ground on the back and sides, which keeps it more temperature-stable than the north-facing house above — but Auckland summers still push ambient temperatures higher than a kitchen or living room would reach. The climate class T rating means the DEWC46D handles this without complaint, in the same way my Liebherr GrandCru handles Queensland summers.
If you're placing a wine cabinet somewhere that isn't climate-controlled — a garage, a utility room, a space that gets warm in summer — checking the climate class rating before buying is more important than most buyers realise. The DEWC46D's T rating is a genuine advantage at this price point.
Dual zone in practice
Two independent zones in a 46-bottle footprint is the defining feature of this cabinet, and it works well. Whites and sparkling in the upper zone at serving temperature, reds in the lower zone at cellar temperature — both available without planning ahead or waiting for a bottle to come up or down to the right temperature.

| The lower zone in action — maturing wines including a Gevrey-Chambertin 1er Cru, Clos du Papillon Savennières, and a 2009 Tamar Ridge Riesling I'm in no hurry to open. |
The lower zone is where I keep wines for the near-to-medium term — reds I'll open in the coming weeks or months, and occasionally a bottle I'm holding for a year or two. For wines I intend to mature for five or more years, they go into the Liebherr. The DEWC46D is not a long-term maturation cabinet at 46 bottles — it's a working wine fridge for the wines you're actually drinking.
Build quality and the UV glass
Six beech wooden shelves in a 46-bottle unit is a detail worth noting. Wire racks are the cheaper option and common at this price point; beech shelving is gentler on labels, less prone to rattling, and a marker of a cabinet that takes wine storage seriously rather than just wine chilling.
The triple-glazed UV-tinted glass door is similarly above the baseline for this price bracket. UV protection matters for any wine stored longer than a few weeks, and triple glazing contributes meaningfully to insulation and temperature stability. These are specifications you typically find on more expensive cabinets.
Reliability after 10 years
The compressor and cooling system have remained functional throughout ten years of daily use. The unit maintains temperature, the door seals properly, and the shelving is in good condition.
The display and interior lighting became intermittently unreliable after nine to ten years — flickering, occasionally unresponsive. I'll be honest: my young children spent considerable time treating the control buttons as entertainment, and this almost certainly accelerated whatever was going to happen eventually. Whether the same would occur without that assistance, I can't say. It's worth knowing regardless.
The cooling system continuing to work while the display components failed is consistent with what I experienced with my Liebherr — the core refrigeration outlasts the electronics. In a wine cabinet, that's the right failure mode.
Real-world capacity
Forty-six bottles, stated. In mixed use — Burgundy-shaped bottles, Champagne, the odd magnum — expect closer to 32–38 usable bottles. Factor in the physical division between two zones and you're looking at roughly 15–20 bottles per zone in practice. That's the right scale for a rotating drinking selection, not a serious growing collection.
What I would change
The temperature controls. They're fiddly enough that I've left them untouched for years rather than make fine adjustments. A clearer, more responsive interface — or a simple dial — would have been far more practical.
The display longevity. The cooling components outlast the electronics, which is arguably the right priority — but at NZ$999 and with a 3-year warranty, the display should last longer than a decade even under occasional misuse.
Current alternatives — DeLonghi no longer makes wine cabinets
DeLonghi has exited the wine cabinet category entirely. If you're looking for a current equivalent, these are the options I'd consider:
Best like-for-like replacement: Robinhood RWCD46BUB — 46-bottle dual-zone compressor, similar dimensions, triple-glazed glass, beech shelves, broadly comparable price. The closest match to what the DEWC46D was.
Budget alternative: Sheffield 46 Bottle Built-in Wine Cooler — similar headline specs at a lower price, but only a 12-month warranty. Treat it as a value option rather than a long-term investment.
Premium step-up: Vintec VWD050SBB-X — dual-zone, 50-bottle, 595mm wide. Significantly more expensive but a stronger wine storage brand with a better long-term reputation. If the budget stretches, this is the more serious cabinet.

Who should buy a compact dual-zone wine cabinet
Buy it if: You need a compact underbench unit. You want to serve whites and reds at different temperatures simultaneously. Your collection is 30–40 bottles in active rotation. Space is the primary constraint.
Don't buy it if: You're building a collection for long-term maturation — the capacity isn't there, and a single-zone cabinet with better maturation credentials is a more focused tool. See the Liebherr GrandCru review for what that looks like at the premium end.
Frequently asked questions
Is the DeLonghi DEWC46D a compressor or thermoelectric wine fridge?
Compressor. Despite being a compact 46-bottle unit, the DEWC46D uses a proper compressor cooling system — not thermoelectric — which gives it better temperature stability and a wider ambient operating range (climate class T, up to 43°C) than thermoelectric alternatives at this size.
Is the DeLonghi DEWC46D still available?
No. DeLonghi no longer manufactures wine cabinets. The closest current alternative is the Robinhood RWCD46BUB, which matches the 46-bottle dual-zone compressor format at a similar price point.
What temperature should each zone be set to?
Upper zone (whites, rosé, sparkling): 7–10°C depending on the wine and your preference. Lower zone (reds at cellar temperature): 12–14°C. The DEWC46D's 5–22°C range per zone gives you plenty of flexibility beyond these defaults.
Can the DeLonghi DEWC46D be used in a garage?
Yes — the climate class T rating means it operates reliably in ambient temperatures up to 43°C. I use mine in a below-stairs garage in Auckland with no issues. In a very cold space (below around 10°C), performance may be affected at the lower end.
How does the DeLonghi DEWC46D compare to the Liebherr GrandCru?
Different tools for different jobs. The Liebherr is a single-zone cabinet designed for serious long-term maturation — larger capacity, built to last decades, priced accordingly. The DeLonghi is a compact dual-zone unit for managing drinking stock and serving temperatures. I use both, for exactly those purposes. See the full Liebherr WKt 5552 GrandCru review.
