Slushies FAQ's

1. What is the most popular slushie flavour?

Blue raspberry reigns supreme as the most popular slushie flavour worldwide and here in Australia! Its vibrant colour and sweet-tart taste make it an instant crowd-pleaser.

At Last St, we have a huge range of Isabella's cordials and syrups you can use to create your own flavour combinations. Some of our most popular slushie flavours include:

  • Blue Raspberry – Our Raspberry Vinegar cordial is the perfect match, we just have a beautiful red colour instead of the blue.
  • Pine Lime – A quintessential Aussie favourite with that nostalgic fizzy drink flavour
  • Fairy Floss – Sweet, pink, and perfect for kids (and Instagram-worthy drinks!)
  • Fruit Tangle – Tastes just like those corner shop lollies we all remember
  • Strawberries & Cream – A nostalgic favourite for little kids and big kids alike
  • Heritage Cola – That classic cola taste everyone loves
  • Watermelon – Refreshing and perfect for hot Aussie summers

Other crowd-pleasers include Sour Apple, Portello, Peaches & Cream, and Tropical Punch. With over 50 Isabella's cordial and syrup flavours to choose from, you can create endless combinations. Slushie, slushy or slushi, we have a flavour for everyone!

Can you make alcoholic slushies?

Absolutely! Alcoholic slushies (also called frozen cocktails or "boozy slushies") are a fun drink alternative! At Last St, we have an extensive range of handcrafted liqueurs and spirits from our Beechworth distillery that work perfectly to add a delicious boozy twist to your slushies. From frozen margaritas to spiked daiquiris, there's a world of possibilities!

Popular alcoholic slushie combinations we recommend:

  • Espresso Martini Slushie – Coffee Liqueur + Pure Spring vodka + ice
  • Salted Caramel Colada – Salted Caramel Liqueur + pineapple cordial + Spiced Rum
  • Chocolate Mint Frozen Cocktail – Chocolate Mint Liqueur + cream + Pure Spring vodka
  • Apple Crumble Slushie – Apple Crumble Liqueur + cinnamon + Pure Spring vodka
  • Butterscotch White Russian – Butterscotch Liqueur + Pure Spring vodka + cream

Creative Premium Twists:

  • Elderflower Gin Slushie – Elderflower cordial + George’s gin + cucumber
  • Lychee Martini Slushie – Lychee, Lime & Lemon Iced Tea cordial + Pure Spring vodka
  • Tropical Whisky Sour – Tropical Punch cordial + whisky Liqueur + lemon

Pro tips for boozy slushies:

  • Add alcohol after the slushie has formed (alcohol doesn't freeze well), or use a lower alcohol ratio to ensure proper freezing
  • Start with 30-60ml of spirits per serve and adjust to taste
  • Our liqueurs are already sweet and flavourful, so you may need less cordial when using them

Explore our full range of spirits and liqueurs online at Last St to create your perfect boozy slushie!

What syrup and cordials do you use for slushies?

At Last St, we offer Isabella's range of concentrated cordials and syrups – handcrafted in Beechworth using pure alpine spring water from our 150-year-old red brick well. These are specifically designed for creating incredible slushies!

Why Isabella's products are perfect for slushies:

  • Highly concentrated – A little goes a long way, so your bottles last longer
  • Heritage recipes – Many dating back to 19th-century formulas we discovered in the brewery basement
  • Versatile – Perfect for slushies, cocktails, sodas, baking, and more
How much flavour do you need?

We find that mixing concentrated cordial or syrups into your slushie machine requires less product than pre-made mixes, so your bottles last longer and you save money!

Be sure to refer to our 'Slushie Maths' guide above to create the ideal mix ratio for your specific machine. Most machines work well with a 1:3 to 1:5 ratio (cordial/syrup to water), but always check your machine's recommendations first. And, always taste and tweak as you create! The fun is in flavour play!

Money-saving bundles: We offer Cordial Bundles at discounted prices – perfect for stocking up on multiple flavours or trying new combinations. Make sure to share your creations with us.

What machine makes the best slushies?

The best slushie machine really depends on your needs and how you plan to use it.

But here's the secret: The machine is only half the equation. What really makes a slushie stand out is the quality of your cordials and flavour combinations.

At Last St, we believe it all comes down to the flavours you use. With Isabella's 50+ handcrafted cordials made from heritage recipes you can get creative, mix flavours, play with colours and tastes – the possibilities are endless.
