Why Should Gelato Be Stored at -12°C to -14°C?

Have you ever wondered: Why does Gelato need to be kept very cold, yet it should not be served at -18°C like conventional frozen ice cream?

A tray of Gelato taken directly from a deep freezer can be so hard that it is difficult to scoop. But when the product is brought to around -12°C to -14°C, Gelato becomes softer, smoother, more elastic, easier to shape, and—most importantly—its flavors become more noticeable.

This is not a random difference. Behind a smooth scoop of Gelato at serving temperature lies a complex balance involving water, sugar, PAC, total solids, fat, Stabilizer, freezing conditions, and storage temperature.

So, what actually happens inside Gelato when its temperature changes?

Let's explore it together with FABBRI 1905 & IKEM.

1. -12°C to -14°C: The Temperature for a Beautiful Scoop of Gelato

First, it is important to clarify one point: -12°C to -14°C is generally a reference range for serving/displaying artisanal Gelato. It does not necessarily mean the ideal temperature for long-term storage.

This temperature range helps Gelato achieve a balance between stability and softness.

• Too cold → Gelato becomes hard.
• Not cold enough → Gelato becomes too soft, melts, and struggles to hold its shape.

Therefore, professional Gelato makers need to find the right balance for their specific recipe.

This is also why a good Gelato recipe cannot be evaluated simply by asking: “Does the Gelato taste good?”

You should also ask: “Does the Gelato reach the right serving condition at the target temperature?”

2. Why Does Gelato Become Hard at -18°C?

Imagine taking a tray of Gelato at around -18°C and immediately trying to scoop it with a spatula.

You will notice:

• The spatula is difficult to push into the Gelato.
• Gelato may crack.
• The surface is hard.
• It is difficult to create beautiful swirls.
• Customers may find it difficult to enjoy immediately.

The reason lies in water. Gelato contains a significant amount of water. As the temperature decreases, more of that water turns into ice.

The lower the temperature → the more water freezes → the harder the Gelato becomes.

When Gelato is brought back to approximately -12°C to -14°C, some of the water is no longer completely frozen, allowing the structure to become softer and more elastic.

That is why Gelato can both hold its shape and remain easy to scoop at the appropriate serving temperature.

3. Why Does Gelato Need to Be “Frozen Properly,” Not Simply “Frozen”?

This is one of the key differences between simply making ice cream and producing professional Gelato.A frozen product is not simply about lowering the temperature as much as possible.

The goal of Gelato production is to control:

• Frozen Water: Determines hardness and the amount of ice in the product.

• Ice Crystal Size:The larger the ice crystals, the coarser the mouthfeel.

• Air Content: Affects lightness, density, and eating sensation.

• Total Solids: Affects body and Gelato structure.

• PAC: Directly affects the ability to control softness at low temperatures.

Therefore: Great Gelato is not the Gelato that is frozen the hardest. It is the Gelato with the best-controlled structure.

4. PAC – The “Key” to Keeping Gelato Soft at Low Temperatures

Have you ever experienced this situation? “The freezer is at -13°C, but the Gelato is still hard!”

Don't immediately increase the freezer temperature.

Instead, look at PAC – Power of Antifreeze. PAC represents the ability of components in the formulation to lower the freezing point.

Simply put: An appropriate PAC level helps prevent Gelato from becoming excessively frozen at serving temperature.

This is why two recipes stored at exactly the same temperature can have completely different textures.

One recipe may have:

Appropriate PAC → soft, elastic, easy to scoop.

Another may have:

PAC too low → hard, difficult to scoop.

Conversely, if PAC is too high:

Gelato may become too soft, melt quickly, and struggle to hold its shape.

This is precisely why recipe balancing is more important than simply adjusting the freezer temperature.

5. Sugar – More Than Just Sweetness

This is one of the most common misconceptions in Gelato making.

Many people think:

“Sugar is only there to make Gelato sweet.”

In reality, sugar also affects:

• Freezing point
• Gelato softness
• Structure
• Melting sensation in the mouth
• Stability during storage

Most importantly, different sugars do not have the same effect.

Sucrose, dextrose, glucose syrup, fructose, and other sugars can have different effects on sweetness and antifreeze properties.

Therefore, changing the type of sugar without recalculating PAC/POD can significantly change the texture of the Gelato.

6. Water – The “Invisible” Ingredient That Determines Hardness

A Gelato recipe containing too much free water may result in:

Large ice crystals → coarse texture → faster melting when the temperature rises.

Conversely, a recipe with too little water or excessively high total solids may cause:

Gelato becomes dense → heavy → hard → difficult to scoop.

Therefore, Gelato makers need to find the right balance between:

Water ↔ Total Solids ↔ Sugar ↔ Fat ↔ PAC

This is why a professional Gelato recipe needs to be calculated rather than simply: “Add the ingredients and adjust based on intuition.”

7. Why Can Pistachio and Fruit Gelato Be Different in the Same Freezer?

Here is an interesting experiment. Take two different recipes and place them in the same freezer at the same temperature:

Pistachio

and

Strawberry

They can have completely different levels of softness.

Why?

Because each recipe has different:

• Water content
• Total solids
• Sugar content
• Fat content
• Ingredients
• PAC

Therefore:

There is no single temperature that can solve the needs of every Gelato recipe.

The range of -12°C to -14°C is an important reference range for serving, but the recipe itself still needs to be properly balanced.

8. Batch Freezer – Where Gelato Structure Is Created

Serving temperature is only the final link in the chain. Gelato quality begins to be determined inside the Batch Freezer.

During batch freezing:

The mix is simultaneously cooled, agitated, and frozen.

This process helps control ice crystal formation and incorporates air into the Gelato structure.

If the freezing process is not appropriate, even if the freezer is later set to -13°C, the product may still fail to achieve the desired texture.

9. Blast Freezer – An Important Step After the Batch Freezer

After leaving the Batch Freezer, Gelato is not yet completely stable.

This is where the Blast Freezer plays an important role.

A Blast Freezer helps rapidly lower the temperature, supporting the control of ice crystal formation and stabilizing the product structure.

It can be understood simply as:

Batch Freezer → Creates the Gelato structure

Blast Freezer → Stabilizes the structure

Display Freezer → Maintains the serving condition

Three pieces of equipment, three different functions.

10. So, What Temperature Should Gelato Be Stored At?

This is an important distinction to make.

Long-Term / Inventory Storage: Gelato is generally kept at a temperature lower than its serving temperature, often around: -18°C or below depending on the equipment and operating process.

Display and Serving: Artisanal Gelato is commonly brought to approximately: -12°C to -14°Cto achieve a condition that is easy to scoop and enjoyable to eat.

Therefore, it is important not to interpret this too simply: “-12°C to -14°C is the ideal temperature for every stage.”

Each stage has a different purpose.

11. Gelato Is at -13°C but Still Hard? Check These 7 Points!

If Gelato is still too hard, check:

① PAC Is Too Low: The formulation may not have sufficient antifreeze power.

② The Sugar System Is Not Properly Balanced: The type and ratio of sugars may not be appropriate.

③ Total Solids Are Too High: Gelato may become dense and hard.

④ Water Is Not Properly Balanced: This affects the amount of ice that forms.

⑤ The Recipe Contains Many Structure-Building Components: Protein, fat, total solids, and other components can all affect texture.

⑥ Gelato Has Just Been Removed from Deep Storage:The product may not have had enough time to reach serving temperature.

⑦ The Actual Freezer Temperature Is Lower Than the Displayed Temperature: The temperature shown on the display does not always accurately reflect the core temperature of the Gelato.

12. Gelato Is at -13°C but Melts Too Quickly?

Conversely, if Gelato is too soft or melts too quickly, check:

Water → PAC → Sugar → Total Solids → Stabilizer → Freezing Process → Freezer Temperature

In particular, if the formulation contains a high amount of free water or PAC is not properly balanced, Gelato may soften quickly even when the freezer temperature is within an appropriate range.

Therefore:

Do not immediately lower the freezer temperature to -18°C.

Doing so may make the Gelato harder, but it will not address the root cause of the formulation.

13. FABBRI 1905 – When Ingredients Become Part of the Formulation

Professional Gelato requires more than just a good machine.

It requires:

Quality Ingredients + The Right Recipe + Suitable Equipment + Precise Technique

This is also why FABBRI 1905 is an important consideration for those developing professional Gelato recipes.

From flavor pastes and Bases to other specialized ingredients, the goal is not simply to create a delicious flavor, but also to achieve a product with:

Clear flavor – smooth texture – good elasticity – stable shape retention – an appealing eating experience

With Gelato, flavor and structure must work together.

• A delicious Gelato that is too hard does not provide a good eating experience.
• A soft Gelato that melts too quickly is not a perfect Gelato either.

14. The Secret Is Not “One Number”

If you remember only one thing from this article, remember this:

No single temperature can rescue an unbalanced Gelato recipe.

• Freezer too cold → Gelato becomes hard.
• Freezer too warm → Gelato melts.
• PAC too low → Gelato becomes hard.
• PAC too high → Gelato becomes too soft.
• Too much water → Greater risk of ice formation and fast melting.
• Total solids too high → Gelato may become heavy and hard.
• Improper freezing → Poor texture.
• Unstable storage → Structural deterioration.

Temperature is only one part of the equation.

The most important factor is:

The balance of the entire system.

15. Perfect Gelato Is When Customers Can “Feel” the Difference

A good Gelato does not require customers to know what PAC is.

It does not require customers to understand POD.

It does not require customers to know how a Batch Freezer works.

What customers actually notice is simply:

• “The Gelato is so smooth.”
• “It is elastic and aromatic.”
• “It scoops beautifully.”
• “It melts so smoothly in the mouth.”
• “The flavor is so clear and pronounced.”

That is the ultimate result of a well-balanced Gelato recipe.
