The Long Island Iced Tea is the cocktail that broke every rule and got away with it. Five spirits in one glass, no tea whatsoever, and a flavour so smooth that most people forget they are drinking the equivalent of three drinks at once. It has been the most ordered cocktail at house parties, nightclubs, and late-night bars since the 1970s for good reason. Here is the authentic recipe, why it works despite all logic, and how to serve it responsibly at events.
Add 15ml each of vodka, gin, white rum, tequila, and triple sec to a cocktail shaker. Equal measures are essential — the balance between the five spirits is what makes the recipe work. If one spirit dominates, the cocktail falls apart.
Add 25ml fresh lemon juice and 15ml sugar syrup. The lemon is doing heavy lifting here — it provides the acidity that masks the alcohol and gives the drink its clean, citrus finish. Bottled lemon juice will taste noticeably worse.
Fill the shaker with ice and shake hard for 10-12 seconds until the outside of the shaker is frost-cold. Shaking integrates the spirits and chills the liquid rapidly, which is important for a drink this strong.
Strain into a highball glass filled with fresh ice cubes. Do not reuse the shaker ice — it has already started to dilute.
Top with a splash of Coca-Cola. This is the most misunderstood step. You want 30-50ml — just enough to turn the drink an iced-tea amber colour. It is not a vodka-and-Coke. The cola provides colour and a hint of sweetness, not volume.
Garnish with a lemon wedge and serve with a straw. The straw is functional, not decorative — it lets the guest sip from the bottom of the glass where the cocktail is most concentrated.
A standard Long Island Iced Tea contains 75ml of spirits at 40% ABV, which equals three UK units of alcohol in a single glass. For context, that is the same as three single-measure gin and tonics or nearly a third of the NHS recommended weekly limit in one drink.
The reason it does not taste strong is chemistry. The five spirits share similar base flavour compounds but have different secondary flavours — the juniper in gin, the agave in tequila, the sugarcane in rum. When combined, these flavours cancel each other's harshness rather than amplifying it. The lemon juice and sugar syrup then coat the palate with acidity and sweetness, further masking the alcohol.
| Drink | Spirits (ml) | UK Units | Approx ABV |
|---|---|---|---|
| Long Island Iced Tea | 75ml (5 spirits) | 3.0 | ~22% |
| Margarita | 50ml (tequila + triple sec) | 2.0 | ~18% |
| Gin & Tonic | 25ml (single) | 1.0 | ~7% |
| Porn Star Martini | 50ml (vodka + Passoa) | 2.0 | ~14% |
| Glass of wine | — | 2.1 | ~13% |
Replace cola with cranberry juice. Produces a pink drink with a sharper, fruitier finish. Popular at summer events.
Replace cola with Midori (melon liqueur). The drink turns bright green and gains a sweet melon flavour. A favourite at themed parties.
Replace cola with bourbon and sweet tea. Stronger and darker, with a genuine sweet-tea flavour.
Replace cola with blue curacao and lemonade. Neon blue, sweeter, and slightly less strong. Very photogenic at events.
Use 10ml of each spirit instead of 15ml, increase lemon and cola. Brings it down to roughly 2 UK units — a more responsible event serve.
At events, the Long Beach and Electric Lemonade variations are the most popular alternatives. Both are visually striking and taste distinct enough from the original to justify having two Long Island-style drinks on the same menu. Our bartenders can advise on which variations work best for your crowd — see the full event cocktail menu.
Long Island Iced Tea is one of the most requested cocktails at events we serve, particularly at birthday parties, house parties, and festival bars. It is the cocktail that guests order when they want something strong, familiar, and satisfying.
Responsible service matters with Long Islands. Our bartenders are trained to monitor consumption and offer lower-strength alternatives when appropriate. We use the standard 15ml-per-spirit recipe (not the 25ml heavy pour that some bars use) and always recommend that event hosts provide food alongside cocktail service. For wedding receptions and corporate events, we can offer the Low-Strength Long Island variation that delivers the same flavour at two-thirds of the alcohol content.
For dry hire events, Long Islands are cost-effective despite requiring five spirits. Each drink uses only 15ml of each, so a single 700ml bottle of each spirit produces approximately 46 cocktails. Factor in lemon, sugar, and cola and the per-drink cost is around £2.50 — competitive with simpler cocktails. See our packages or cost guide for full pricing.
