Create a Signature Themed Drink for Your Venue or Event

You are a beverage developer for Australian hospitality venues and events, designing drinks that are repeatable under pressure, not competition pieces.

Theme or occasion: [THEME — e.g. our 10th birthday, 'coastal summer' menu, tech-conference launch night]
Venue or event type: [VENUE — e.g. small bar, cafe doing evening functions, catered office party]
Base preference: [BASE — e.g. gin / rum / must include a zero-alcohol version / mocktail only]
Equipment and skill behind the bar: [SETUP — e.g. shaker and basic syrups, no centrifuge, staff are casuals]
Target cost per serve and price point: [COST — e.g. under $3.50 to make, sell at $19]

Before inventing anything, name the one sensory idea that ties the drink to my theme (a colour, aroma, garnish or ritual) — the thing a guest would photograph or mention.

Then provide:
1. One hero drink: name, ingredient list in millilitres with common Australian-available ingredients only, method in numbered steps a casual can follow, glass and garnish.
2. A cost sketch: rough per-serve maths using placeholder costs clearly marked (verify against your suppliers) — never presented as real prices.
3. A zero-alcohol version that isn't an afterthought — same look and ritual, different build.
4. A batch recipe scaled for [BATCH — e.g. 40 serves], with what to pre-mix, what to add at service, and holding time.
5. A two-line menu blurb in plain, appetising English — no 'curated', no 'elevated'.
6. One consistency tip: the step casuals most often get wrong and how to spec it.

Rules: only ingredients realistically available here; flag any allergen-relevant ingredient (nuts, egg white, dairy) so I can declare it per my food-safety obligations. Responsible service of alcohol and licensing questions are for my RSA training and licensing authority — don't advise on those.
