In commercial scenarios, you can always see a variety of drinks being placed in commercial glass-door beverage display refrigerators or open chillers. This is not only to better display these drinks but also because of the better flavor and longer shelf life.
This article will introduce the optimal storage temperature conditions to preserve some common drinks and explain why they need to be stored at low temperatures.
Safety Tips: Do not put any carbonated soft drinks or beer in the freezer (below 0 degrees) to avoid an explosion. This is because carbon dioxide is released and accumulated in the sealed container during the freezing process, causing the internal pressure to increase sharply, and eventually exceeding the container’s tolerance limit and causing an explosion.
Perfect Temperature for Alcoholic Beverages
Best Fridge Temperature for Beer
Since the temperature of the beer may rise due to the warmth of the hand and the room temperature of the wine glass, the beer storage temp should be slightly lower than the best drinking temp.
Lager beer uses bottom-fermenting yeast, and the fermentation and cellaring temperature is lower, the fermentation time is longer, and the low-temperature cellaring time is longer, which helps to maintain the quality and taste of the beer.
German Pilsners, wheat beer, and Cologne beer highlight fresh, floral, and fat-scented styles, which are suitable for drinking at a higher temperature. The best drinking temperature for IPA, Porters or stronger beers is higher.
| Beer Type | Optimal Storage Temperature |
| Light Lagers | 33-40°F (1-4°C) |
| Pilsners, Wheat Beers, Kölsch | 38-45°F (3-7°C) |
| Ales (including IPAs), Stouts, Porters | 45-50°F (7-10°C) |
| Stronger Beers, British Bitter | 50-55°F (10-13°C) |
Reasons for Optimal Beer Storage Temp
High temperature storage has a significant impact on the flavor and shelf life of beer. On the one hand, high temperatures can make the carbon dioxide and alcohol in beer more volatile, causing the beer to become sour, thicker, or taste different.
On the other hand, high temperatures can accelerate the deterioration of beer, and if stored at temperatures above 25 °C, the shelf life will be greatly shortened.
Too low a temperature can affect the flavor or appearance of the beer. Too low a temperature can cause the beer to have a “cold haze” phenomenon, which refers to the liquid becoming cloudy after the beer is cooled or frozen, but when the temperature rises, this turbidity disappears and the beer returns to clarity.
Although the cold haze phenomenon does not affect the taste of the beer or pose a threat to drinking safety, it does give the beer a cloudy appearance, which may affect consumers’ desire to buy.
In addition, too low a temperature can cause the beer to be over-carbonated, causing the beer to foam continuously and in large quantities. This phenomenon usually results in a poor taste, a weak taste, and “hissing” bubbles like soda.
Best Fridge Temperature for Wine
| Wine Type | Subcategory | Optimal Storage Temperature | Examples |
| Red Wines | Light, Fruity Reds | 55-60°F (13-16°C) | Pinot Noir, Lambrusco, Sherry |
| Medium-bodied Reds | 57-62°F (14-17°C) | Merlot, Malbec | |
| Full-Bodied, Tannic Reds | 60-65°F (16-18°C) | Cabernet Sauvignon, Syrah, Bordeaux, Port | |
| White Wines | Light, Crisp Whites | 45-50°F (7-10°C) | Sauvignon Blanc, Pinot Grigio |
| Medium, Aromatic Whites | 50-55°F (10-13°C) | Chardonnay, Riesling | |
| Sweet, Dessert Whites | 45-50°F (7-10°C) | Moscato, Sauternes | |
| Rosé Wines | Rosé | 50-55°F (10-13°C) | |
| Sparkling Wines | Sparkling Wines | 40-45°F (4-7°C) | Champagne, Prosecco |
Reasons for Optimal Wine Storage Temp
High temperature accelerates the chemical reactions and microbial activities of wine, causing the wine to mature faster. This acceleration is not always positive, it makes the flavor of the wine develop too quickly, causing it to lose complexity and layering.
High temperature accelerates the oxidation process of wine, causing the chemicals in the wine, such as organic acids and phenolic compounds, to decompose, thereby destroying the acidity balance and flavor characteristics of the wine. This oxidation will not only change the color and flavor of the wine, but may also cause it to deteriorate.
In addition, high temperatures will make the tannins in the wine more prominent, the taste will become astringent and fierce, and the originally soft and smooth wine will become rough and difficult to drink.
Too low temperature may slow down the maturation process of wine or even stagnate.
Too low temperature will also directly destroy the taste structure of the wine, damage the body of the wine, and the flavor substances cannot be fully experienced. At this time, there is no difference between wine and grape juice.
Perfect Temperature For Non-Alcoholic Beverage
Best Fridge Temperature for Milk and Yogurt
Fresh Milk (Pasteurized), ESL milk (Extended Shelf Life Milk), and yogurt are usually stored at 32°F to 39.2°F (0-4°C). UHT milk (Ultra-High Temperature Sterilized Milk) can be stored at room temperature, but once opened, it must be refrigerated at 32°F to 39.2°F (0-4°C) and consumed as soon as possible.
Reasons for Optimal Milk Storage Temp
Apart from the taste and texture, the importance of the right refrigeration temperature for milk is two-fold: to prevent bacterial growth and nutrient loss.
On the one hand, both fresh milk and ESL milk contain natural bacteria that will accelerate growth at 7°C (45°F) or higher, causing sourness and off-flavors, and producing toxins, significantly shortening the shelf life of milk.
In addition, freezing does not kill all bacteria. If the conditions are not right during the thawing process, bacteria may multiply rapidly, causing the milk to deteriorate, which can easily cause diarrhea or other gastrointestinal problems.
On the other hand, when stored at a suitable temperature, the nutrients in milk are relatively stable, but high temperatures can accelerate the loss of nutrients or destroy B vitamins and other sensitive nutrients.
Freezing denatures the protein in the milk and stratifies the fat. After thawing, the protein and fat precipitate and coagulate, which is not conducive to human absorption and reduces the nutritional value. During the freezing process, the vitamins in the milk are also oxidized and lost.
Best Fridge Temperature for Carbonated Soft Drink
You may often see Coca Cola display fridges or Pepsi display fridges in convenience stores or supermarkets. Coke is a common carbonated soft drink. Since it can be stored at room temperature, the storage temperature range of carbonated soft drinks is extensive, but the most recommended storage range is 35.6°F to 42.8°F (2-6°C).
Reasons for Optimal Carbonated Soft Drink Storage Temp
Although carbonated drinks can be stored at room temperature, bubbles are one of the pleasures of drinking such drinks. To ensure the best taste and safety, refrigeration before drinking is recommended.
A large amount of carbon dioxide gas is dissolved in carbonated drinks. Refrigeration can keep the carbon dioxide in carbonated drinks in a relatively stable dissolved state and avoid gas release problems caused by temperature fluctuations.
