Benefits of Clear Ice vs Cloudy Ice

When it comes to ice for your drinks, you might not give it much thought, but there's more to ice than meets the eye. Clear ice and cloudy ice are not created equal, and each has its own set of advantages and drawbacks. Let's explore the benefits of clear ice compared to cloudy ice:

Clear Ice:

1. Aesthetics:

  • Elevated Presentation: Clear ice cubes are visually stunning and enhance the overall presentation of your drinks, making them look more appealing and sophisticated.

  • Visual Clarity: The crystal-clear appearance of clear ice adds a touch of elegance to cocktails and beverages, creating a more visually appealing experience.

2. Flavor Preservation:

  • Unaltered Taste: Clear ice maintain the integrity of your drink's flavor. They do not introduce unwanted flavors or dilute your beverages as they melt, allowing you to enjoy the full taste of your drink.

3. Purity:

  • Impurity-Free: Clear ice undergoes a controlled freezing process that effectively eliminates impurities. This ensures that your ice is free from off-putting tastes or odors that can sometimes be present in cloudy ice.

4. Craftsmanship:

  • Crafted with Care: Making clear ice requires attention to detail and precision, reflecting a commitment to the quality of your beverages.

  • Enhanced Drinking Experience: The effort put into creating clear ice enhances the overall drinking experience, showcasing a dedication to craftsmanship.

Cloudy Ice:

  • Ease of Production: Cloudy ice is the result of a simple and straightforward freezing process. It doesn't require any special equipment or techniques, you could just use a simple ice tray.

2. Quick Freezing:

  • Rapid Formation: Cloudy ice cubes freeze faster than clear ice due to their less controlled freezing process. This can be advantageous when you need ice in a hurry.

3. Accessibility:

  • Readily Available: Cloudy ice is typically what you get from your refrigerator's ice maker or standard ice trays, making it widely accessible and convenient for everyday use.

How to Make Perfectly Clear Ice Cubes?

Now that we've established the importance of clear ice, let's explore how to create them in the comfort of your home. But before we delve into the methods, it's essential to understand the science behind crystal-clear ice and acquaint yourself with the concept of directional freezing and removing trapped air.

The Science Behind Crystal Clear Ice

To grasp how to make clear ice, it's crucial to understand the science behind it. The key lies in controlling the freezing process to allow the ice to form in a single, uniform layer. This prevents the entrapment of impurities and tiny air bubbles, resulting in the coveted clarity.

The freezing process begins with the slow cooling of water, typically from top to bottom or from the outside in. This controlled freezing method forces impurities and tiny air bubbles to move away from the forming ice. The result? A perfect, clear ice that's both visually stunning and taste-neutral.

What Is Directional Freezing?

Directional freezing is the technique used to create crystal ice. As mentioned earlier, it involves freezing water in a specific direction, usually from top to bottom or from the outside in. By carefully managing the freezing process, you can ensure that impurities are pushed away from the developing ice, leaving you with flawless, clear ice.

Now that we've laid the groundwork, let's explore two popular methods for making clear ice at home, each with its own advantages and disadvantages.

How to Make Clear Ice at Home

1. Clear Ice from the Cooler method

This method involves using a standard cooler or ice tray to create crystal-clear ice cubes. It's a straightforward approach that doesn't require any special equipment.


  • Minimal equipment is needed.

  • Suitable for beginners.


  • Longer freezing time.

  • Limited ice size and shape options.

  • May require multiple attempts for perfect clarity.


  1. Fill the Cooler: Begin by filling your cooler with distilled water. Using distilled water is crucial for achieving optimal clarity.

  1. Position the Cooler: Place the filled cooler in your freezer. Make sure it sits level to ensure even freezing.

  2. Freeze Gradually: Allow the water to freeze slowly over a period of 12 to 24 hours. The slower freezing process is essential for pushing impurities away from the forming ice.

  3. Extract the Ice: Once fully frozen, remove the cooler from the freezer. You'll notice that the top layer is cloudy, while the bottom portion is clear. Carefully chip away the cloudy layer to reveal the pure ice beneath.

  4. Cut into Desired Shapes: Cut the clear ice block into the desired shapes or sizes for your drinks. You can use a sharp knife or ice pick for this step.

2. Crystal Ice with the Berlinzo Clear Ice Maker

Is clear ice only for alcoholic drinks?

No, clear ice can enhance the quality of any beverage, from water and iced tea to soda and cocktails. Its clarity and purity benefit all types of drinks.

Can I use tap water to make clear ice or bottled water?

While tap water can be used, it may contain impurities that affect the clarity of the ice. For the best results, it's recommended to use distilled water.

How long does it take to make clear ice in a cooler?

The freezing time in a cooler can vary but typically takes 12 to 24 hours, depending on the size of the ice block and your freezer's temperature. Patience is key to achieving clear ice with this method.

Do I need special molds for clear ice in the Berlinzo Ice Maker?

The Berlinzo Ice Maker comes with specialized molds designed for clear ice production. Using these molds ensures consistent results and makes the process easier. You could buy additional ice mold to produce ice of different forms.

Can I flavor clear ice with fruits or herbs?

Yes, you can add flavor to your clear ice by placing slices of fruits or herbs in the molds before freezing. This not only adds a unique twist to your drinks but also enhances the visual appeal of your clear ice cubes. Experiment and create ice that complements your favorite beverages perfectly.

Does Boiling Water Make Clear Ice?

Boiling water can help reduce the air content in the water, which is one of the factors contributing to cloudy ice. When you boil water, it releases dissolved gases, such as oxygen and carbon dioxide. These gases can form tiny air bubbles in the ice as it freezes, leading to cloudiness. By boiling water before freezing it, you can reduce the number of air bubbles, potentially resulting in clearer ice. However, it's essential to note that while boiling water can help, it may not guarantee perfectly clear ice on its own.
