Selection Criteria Wine Coolers

Methodology

Topten.eu presents the most energy efficient wine coolers on the European market. Only E and F models are listed on topten.eu. All listed products use natural climate-friendly refrigerants.

Scope

The wine coolers listed:

have no compartments other than one or more wine storage compartments
belong to one of two categories: one temperature zone or multi temperature zones
are designed either for short-term wine storage to bring wines to ideal drinking temperature (serving) and/or for long-term wine storage to allow wine to mature (ageing)
are available on the European market

Technical criteria

All models on Topten.eu meet the following criteria:

Natural refrigerant with global warming potential (GWP) of ≤ 3 (e.g. R290/propane, R600a/isobutane, R744/CO2)
Minimum energy efficiency class as given in the following table:

Category	Energy efficiency class
One temperature zone	minimum F
Multi temperature zones	minimum F

Data sources

Manufacturers’ declarations according to the EU energy label (regulation (EU) No 2019/2016).

Order of presentation

Products are ranked according to energy efficiency index. The order of presentation can be changed by selecting the sort order on the top right side of the product list.

Glossary

Brand, Model, Other models

Products’ model and brand name with link to its specific website. Other very similar products are listed as other models.

Electricity costs

Costs for electricity during product's life time. Assumptions:

Typical life time: 10 years
Annual energy consumption: according to EU energy label in kWh/year
Tariff of electricity: 0.3 €/kWh (however can be large differences depending on country or electrical utility)

Total net volume

Sum of the storage volumes of all compartments in liters according to the EU energy label.

Max. number of 75cl Bordeaux bottles

Maximal number of standard Bordeaux bottles of 75 centilitres that may be fitted in the appliance in accordance with the manufacturer’s instructions. Size of a standard bottle by the EU-Norm NF H 35-124:2006-07-22: H: 300.5 mm, Ø: 76.1 mm.

Storage temperatures

Storage temperature range in °C.

Temperatures zones

Number of zones with the possibility to have different temperatures, according to the declared design of the appliance.

Typically, each zone is design for a different purpose, for example: for aging (10 to 15°C), for chilling champagne (4 to 6°C) or for serving red wine (18°C).

Independent compartments

Number of different temperature zones, which are physically separated and temperature is independently controlled.

Energy efficiency class

Energy efficiency class according to the EU energy label. Most efficient is A, least efficient is G.

Energy Efficiency Index

Energy efficiency index (EEI) according to the EU energy label. Value in percent (%). The lower the value, the more efficient the product.

Energy

Annual energy consumption in kWh/year according to the EU energy label.

Energy efficiency class	EEI	EU energy label
A	≤ 41
B	41 < EEI ≤ 51
C	51 < EEI ≤ 64
D	64 < EEI ≤ 80
E	80 < EEI ≤ 100
F	100 < EEI ≤ 125
G	EEI > 125

Refrigerant

R600a (isobutane, natural climate-friendly refrigerant)
R290 (propane, natural climate-friendly refrigerant)
R744 (CO2, natural climate-friendly refrigerant)

Type

Compression
Thermoelectrical (without refrigerant)

Noise

Airborne acoustical noise emissions expressed in dB(A) according to the EU energy label.

Ambient temperature

Manufacturer's recommendation. Suitable temperature range for placing the cabinet.

Name	Climate class	Ambient temperature range
SN	Extended temperate	+10°C to +32°C
N	Temperate	+16°C to +32°C
ST	Subtropical	+16°C to +38°C
T	Tropical	+16°C to +43°C

Dimensions

Width x depth x height in cm.

Countries available

This item displays the availability of models in European countries according to producers’ information. "EU" means that the model is available in all or most European countries. If the model is available in a number of countries only they are indicated by country codes according to ISO. "On demand" means that producers could not indicate the availability and that consumers have to ask in their countries on their own.
