Quick answer
Fill the Au Colour Changing Cup with a well-chilled drink and enough ice to keep it cold, then hand wash and air dry it after each use. The colour shift depends on sustained cold, so the cup works best as a serving vessel for drinks you have already chilled.
Why the cup needs cold, not just a cold-looking drink
The Au Colour Changing Cup is designed to change colour when a cold drink is added. That makes temperature the main variable: a drink that is merely cool may produce a weaker or slower change than one poured straight from the fridge or freezer. For vodka serves, chill the vodka and any mixer first, then pour over ice in the cup. The cup is a serving piece, not a chiller, so it will not rescue a warm drink.
When the cup is the wrong choice
The cup is a limited-edition, reusable 395ml vessel with a purple and blue design, and it is best treated as a cold-serve accessory rather than an all-purpose tumbler. Avoid using it for hot drinks, and do not assume it is insulated or dishwasher-safe, because those specifications are not supplied. If you need a cup for long outdoor sessions or hot beverages, choose a different vessel and keep this one for chilled vodka drinks and summer gatherings.
Step-by-step: using and caring for the Au Colour Changing Cup
- Chill the drink before it goes in: Store your vodka and any mixer in the fridge until you are ready to serve. Pour the chilled liquid into the cup over ice rather than adding warm liquid and waiting for the cup to cool it. Checkpoint: the cup changes colour from the cold drink, so pre-chilled ingredients give the clearest effect.
- Add ice first, then pour: Fill the cup partway with ice, then pour your chilled vodka drink over it. Leave a little headroom so the drink does not spill when you move the cup. Common mistake: overfilling a 395ml cup with ice and liquid can cause overflow once the ice settles.
- Watch the colour change as a cold cue: Use the colour shift as a visual check that the drink is cold. If the colour barely changes, the drink or the cup is not cold enough yet. Do not put the cup in the freezer to force the change; chill the drink instead.
- Hand wash after each use: Rinse the cup with warm water and a little washing-up liquid, then wash gently by hand. Avoid abrasive sponges and harsh chemicals that could dull the printed design. Checkpoint: hand washing protects the colour-changing finish; dishwasher use is not confirmed for this cup.
- Air dry fully before storing: Leave the cup upside down to drain and air dry completely before stacking it in a cupboard. Store it away from heavy items that could scratch the outside. Common mistake: storing a damp cup can trap moisture and odour.
