Science, Salt, and Sheffield Grit: The Toffee Vodka Takedown
Share

Quick Summary / TL;DR
- The Issue: A batch of Sticky Situation Handcrafted Toffee Vodka developed a stubborn butterfat emulsion that wouldn't clear through standard 0.5-micron filtration.
- The Obstacle: Our freezers were packed tight with seasonal Chuckleberries and Sloes, leaving zero room for chill-filtering.
- The Sheffield Hack: We used a kitchen sink "bain-marie" to heat the spirit to 50°C, melting the fats and resetting the emulsion.
- The Cold Crash: Rapidly cooled the spirit using an ice, water, and salt mixture to force the fats to clump together (flocculate).
- The Result: After an overnight soak and one last filter, we achieved a crystal-clear vodka with a deep butter-toffee punch.
Distilling isn't always about fancy copper stills and botanical charts. Sometimes, it’s about standing over a kitchen sink in Sheffield, wondering why your latest batch of Sticky Situation Handcrafted Toffee Vodka looks more like a muddy puddle than a world-class spirit.
At Hawkins Distillery, we’re proud to be Actually Made in Sheffield. That means when things go sideways, we don’t call a consultant; we use our heads, a bit of science, and a healthy dose of Yorkshire grit to fix it. This is the story of how we took down a stubborn butterfat emulsion using little more than a hot tap and a bag of salt.
The Cloudy Catastrophe
We’ve been handcrafting spirits in-house since 2019, and if there’s one thing we’ve learned, it’s that natural flavours are temperamental. When you’re making something like our Sticky Situation Handcrafted Toffee Vodka, you’re dealing with real fats.
Usually, a 0.5-micron filter does the job, stripping out the bits you don't want while leaving the flavour intact. But this time? No chance. The emulsion was so stable it laughed at the filter. It stayed cloudy, stubborn, and, frankly, not up to the Hawkins standard.
The Freezer Crisis
The textbook solution for a cloudy spirit is "chill-filtering." You stick the batch in a freezer, wait for the fats to solidify, and then skim them off or filter them out while they’re cold.
Simple, right? Except for one tiny problem: our freezers were absolutely rammed.
We’re right in the middle of processing our seasonal hauls. We’ve got bags of Chuckleberries, Rhubarb, and Sloe berries taking up every square inch of cold storage. The Chuckleberries were just hogging freezer space; it was the Sticky Situation Handcrafted Toffee Vodka that needed tapping and salting. There wasn’t enough room left in those freezers for a pint of milk, let alone a massive vat of vodka.
We had to get creative.
The "Sheffield Bain-Marie"
If we couldn't get the spirit cold enough to break the emulsion immediately, we decided to do the opposite: we turned up the heat.
Butter has a melting point of around 35°C. To get those stubborn butterfats mobile and ready to move, we needed to go higher. We rigged up a makeshift bain-marie using the most sophisticated equipment available, the distillery kitchen sink and the hot tap.
We brought the spirit up to a steady 50°C. By holding it at this temperature for a couple of hours, we essentially "reset" the emulsion. The fats melted completely, becoming liquid and mobile within the alcohol. This was the setup for the big crash.

The Science of the "Cold Crash"
Once the fats were fully melted and "unlocked" from their stable state, we needed to shock them. Rapid cooling forces these fat molecules to bump into each other and stick. This is called flocculation. Instead of millions of tiny particles staying suspended, they join up into larger clumps that are much easier to catch in a filter.
To do this without a freezer, we went old-school.
- Initial Rapid Cooling: We ran cold water over the container to drop the temp from 50°C as fast as possible.
- The Ice Bath: We moved the whole container into a larger vat and packed it with ice and water.
- The Magic Ingredient: We dumped a load of salt into the ice bath.
Why salt? Because salt lowers the freezing point of water. That was the trick that let the bath drop below zero overnight, far colder than ice water on its own. We left it outside in the cold Sheffield air and let the salty slush do the hard graft.

The Transformation: From Cloudy to Crystal
Before the final filter did its thing, the batch looked exactly like the sort of mess that makes a distiller mutter under their breath. Cloudy, heavy, and absolutely not shelf-ready.

Batch clarification in all its messy glory: a proper cloudy infusion that still had a fight left in it.
And then came the payoff. This is what all that Sheffield graft is for: absolute clarity. Clean, bright, and looking like it should.

The "after" shot: what Sheffield grit achieves when the batch finally comes good. Crystal clear and ready for action.
The Glorious Result
When we came back the next morning, the transformation was staggering. The magic ingredient really was the salt. It dragged the temperature below zero overnight and gave the fats exactly the shock they needed to clump together properly.
We ran it through the final filter one last time, and out came Sticky Situation Toffee Vodka. Crystal clear, sparkling, and packed with the deep, rich toasted sugar notes we were after. No cloudiness, no sediment, just proper, handmade vodka.
Why We Bother
You might ask why we don't just use artificial flavourings or "toffee-flavoured" syrups like the big industrial brands do. Those things don't go cloudy because they aren't real.
We use natural flavours because that's the Sheffield way. We pursue perfection in distillation because we want to honor the city’s legacy of craftsmanship. If that means we have to spend half the night messing about with salt and ice in a kitchen sink, then that’s what we do.
Whether it's our 4Ships Navy Strength Gin or a batch of experimental Green Apple Vodka, every bottle that leaves this distillery has had someone’s undivided attention, and occasionally a bit of sink-based science.
FAQ: The Toffee Vodka Takedown
Why does vodka go cloudy in the first place?
Usually, it’s due to "louching" (essential oils coming out of solution) or, in this case, butterfat emulsions. When you use real ingredients like toffee or butter, the fats want to stay suspended in the liquid. If the temperature changes or the ratio isn't perfect, they form a cloudy mist.
Can I try this at home?
If you’re making your own infusions, the "ice and salt" trick is a great way to clarify liquids without needing a commercial freezer. Just be careful with glass containers and rapid temperature changes, you don't want them cracking!
Does the salt get into the vodka?
Nope! The salt stays in the "cooling jacket" (the water outside the container). The vodka stays sealed and salt-free inside its own vessel.
Where can I buy the Sticky Situation Handcrafted Toffee Vodka?
Check out our Vodka Collection to see what’s currently in stock. We produce in small batches, so when it's gone, it's gone!
What's a Chuckleberry?
It’s a cross between a gooseberry, a redcurrant, and a jostaberry. It’s tart, dark, and makes for a bloody brilliant vodka.
