Behind the Flavours: How We Develop Our Signature Slush Syrups

Creating a good slush flavour is about more than choosing a name and adding colour.

A flavour that works well in a fizzy drink does not always taste the same once frozen. That is why every Florida Syrups slush flavour goes through a development and testing process before it becomes part of the range.

We develop our slush flavours in-house, usually starting with either an existing Florida Syrups SodaStream-compatible flavour or a new idea that comes from within the team.

From there, we create several samples, compare them and test the most promising versions as finished frozen slush drinks.

Where Do New Slush Flavour Ideas Come From?

Most new slush flavours begin in one of two ways.

Sometimes we start with an existing flavour from our SodaStream-compatible range that we think would work well as a frozen drink.

Other times, someone in the office comes up with a new idea that we think is worth developing.

That gives us a starting point, but the first version is rarely the final one.

Are Slush Flavours the Same as Our SodaStream Syrups?

Not exactly.

The aim is often to keep a familiar flavour profile, especially when a slush flavour starts with an existing SodaStream favourite.

However, fizzy drinks and frozen slush behave differently.

Freezing can change how strong, sweet, sharp or aromatic a flavour seems. As a result, the formulation may need adjusting before it works properly as a slush.

That is why we develop and test the frozen version separately.

How Many Samples Do We Make?

There is no fixed number.

We usually make several samples of a new flavour before deciding which version works best.

Each sample may be slightly different in areas such as flavour strength, colour or sourness.

We then compare them and refine the formulation until the overall balance feels right.

What Do We Look for When Testing a Slush Flavour?

We judge the flavour as a complete finished drink rather than looking at one factor in isolation.

We assess:

• Colour
• Smell
• Taste
• Overall flavour strength
• Balance
• Sourness, where the flavour is intended to be sour

For example, a Sour Cherry or Sour Apple needs enough sharpness to taste genuinely sour without losing the underlying fruit character.

A flavour such as Cream Soda needs a very different balance because the aim is smoother and softer rather than sharp.

Why Do We Test Flavours as Frozen Slush?

Because that is how the customer will actually drink them.

We test developing flavours as finished frozen slush drinks, rather than relying only on how they taste as liquids.

Freezing can change the way a flavour comes across.

A sample that tastes right before freezing may seem weaker, sharper or simply different once frozen.

Testing the final drink therefore helps us judge whether the flavour works in the form it is actually intended to be served.

How Do We Turn Familiar Soda Flavours into Slush?

Some slush ideas begin with established Florida Syrups SodaStream flavours.

Cream Soda, Classic Cola and Bubblegum, for example, already have clear flavour profiles.

When we adapt one for slush, the goal is to keep that recognisable character while making sure it still works once frozen.

So the slush version is not simply a SodaStream syrup with a different label.

It is developed as a frozen-drink version of the flavour.

How Do We Test Sour Slush Flavours?

Sour flavours need extra attention to balance.

It is not enough for them to taste strongly acidic. The fruit flavour still needs to come through clearly.

When testing flavours such as Sour Apple, Sour Cherry, Sour Lemon or Sour Raspberry, we judge whether the sourness feels right alongside the underlying flavour.

Too little sourness and the drink may lose its intended character.

Too much and the fruit itself can become harder to recognise.

That is why sour flavours usually need careful comparison between several samples.

Why Does Colour Matter in a Slush Drink?

Slush is a highly visual product.

People often see the colour before they taste the drink, so the appearance needs to fit the flavour and the type of drink we are trying to create.

We therefore assess colour alongside taste and smell during development.

The finished frozen drink should look consistent with what someone would reasonably expect from that flavour.

Why Does Smell Matter?

Aroma is an important part of flavour.

Before you taste a drink, its smell already influences what you expect.

That is why we check whether the aroma supports the intended flavour rather than judging taste alone.

How Do We Decide a Slush Flavour Is Ready?

A flavour is ready when the finished frozen drink gives us the overall result we are looking for.

There is no single measurement that makes that decision.

Instead, we ask:

• Does the colour look right?
• Does it smell like the intended flavour?
• Does the taste match the original idea?
• Is the flavour strong enough once frozen?
• If it is sour, is the sourness balanced properly?
• Would we be happy to sell the finished slush?

Only once we are satisfied with the overall result do we move forward with the flavour.

Why Do We Develop Our Slush Flavours In-House?

Developing the flavours ourselves gives us direct control over the process.

We can start with an idea, create several samples, freeze them, taste them, make changes and repeat the process until we are happy with the result.

It also allows us to build on flavours we already know well from our SodaStream-compatible range while still treating the slush version as a separate product.

Frequently Asked Questions

How does Florida Syrups develop new slush flavours?

We usually begin with either an existing SodaStream-compatible flavour or a new idea created in-house. We then make several samples, compare them and test the strongest versions as finished frozen slush drinks.

Do you test slush flavours in frozen form?

Yes. We test them as finished frozen drinks because freezing can change the flavour, aroma and overall balance.

What do you judge when testing a new flavour?

We assess colour, smell, taste, flavour strength, overall balance and, for sour flavours, the level of sourness.

Are slush versions identical to SodaStream syrups?

No. They may be based on the same flavour profile, but the slush version is developed separately so that it works properly as a frozen drink.

How many versions of a flavour do you make?

There is no fixed number. We usually make several samples and refine them until we are happy with the finished frozen product.

From Idea to Finished Slush

A new slush flavour usually starts with a simple idea.

What comes next is the important part: making samples, comparing them, freezing them, tasting them and refining the details.

By testing colour, smell, taste and overall balance in the final frozen product, we can make sure each flavour works as a slush rather than simply assuming that a liquid flavour will behave the same way once frozen.

That is how a flavour moves from an idea in the office to a finished Florida Syrups slush product.
