Wine Temperature And How It Affects Wine Tasting

Wine is a sensitive and complex combination of chemical components, and the way it is crafted depends on various processing operations and decisions. Temperature plays a significant role at various stages during the lifetime of wine and continues to be critical in maintaining wine in its optimal state up to transportation and storage.

How Wine Temperature Affects Wine Quality

Elevated and fluctuating temperature can accelerate a wine’s ageing process and can also alter its colour and its sensory attributes, in terms of aroma and mouthfeel. There are seven main critical control points at which temperature needs to be adequately controlled, namely:

1. Crushing,

2. Fermentation,

3. Blending,

4. Maturation,

5. Bottling,

6. Shipping, and

7. Storage.

The chemistry changes that occur from elevated temperatures in red wines are generally more complex than they are in white wines. However, white wines are more heat-sensitive. High temperatures reduce sulphur dioxide levels which are important in preventing wine from reacting with oxygen. This results in browning (e.g. in white wines) and off-odours (oxidation). Sulphur dioxide is also important in inhibiting the growth of bacteria and undesirable wild yeasts.

Unfortunately, changes in wine become apparent only when the wine reaches you. Your part in storing wine well until you come to taste it is also critical. Wine should be stored in cool cellars or air-conditioned facilities at 15–20°C. A wine that is held at a low temperature (e.g. less than 10°C) is less suspectible to spoilage, but will also take much longer to develop1.

The ideal temperature in serving wine then comes as an important factor as to what aromas you’ll smell and what flavours you’ll taste. Here are some best practices on the ideal wine serving temperature based on the style of wine.

Ideal Wine Temperature For Serving Wine

Generally speaking, it is better not to serve white wines too cold or reds too hot. Remember that the cooler the wine, the less aroma will volatilize in your glass. This tip comes in handy when it comes to lower quality wines as a cooler temperature will conceal potential flaws in the aromas.

In determining whether the temperature is good, follow these quick tips:

• If you smell too much alcohol, then it might be that the wine is too warm and you need to cool it down.

• If the wine does not lift many aromas to your nose and barely has a flavour, then most probably the wine is colder than it should be and you need to warm it up a bit. Depending on whether it is too cool or not, you can start by warming the glass in the palm of your hands. Otherwise, leave it for a while at room temperature before beginning your wine-tasting experience.

You may always serve wine according to your personal preferences. However, starting with what is generally considered to be the ideal serving temperature by type of wine, allows you to reap better the aromas and flavours of the wine. After that, go ahead and experiment to come up with the temperature that works best for you.

Wine Coolers

Nowadays you are spoilt for choice when it comes to wine coolers. You can find wine coolers in various sizes, built-in or free-standing, and in a variety of designs that aligns with your interior home décor.

In ensuring your wine is kept at the optimum temperature and is protected against humidity, for Maltese residents I recommend you give Crosscraft a visit. Crosscraft offers a wide range of built-in wine coolers by Caple. If you have forgotten to incorporate a wine cooler when designing your home or have developed a passion for wine afterward, you can rest assured that at Crosscraft you can also find free-standing wine coolers. For international clients, you may find wine coolers here.
