Bespoke cocktail boxes are pre-mixed, ready-to-drink cocktails packed to your specification and delivered as a complete drinks solution for weddings, corporate events and parties. At Letterbox Cocktails, we build every box around your guest list, your menu and your branding, so nobody queues at a bar while the speeches start.
The maths is simple. A hired bar means staff costs, glassware, ice runs and a drinks menu that runs out halfway through the night. A curated collection of bottled cocktails arrives portioned, labelled and ready to serve. Guests open a box, pour over ice, and they're drinking within seconds.
What most guides miss is that the real advantage isn't convenience. It's control. You decide the exact cocktails, the measures, the strength and the presentation before the day arrives, rather than hoping a bartender interprets your brief correctly at 9pm.

Ordering is a four-step process: pick your cocktails, choose your measures, set your quantity, then confirm your delivery date. Our build-your-own bundle lets you assemble the box yourself, mixing flavours across the range until the selection fits your event.
Start with the guest count, not the drinks list. A 40-guest wedding with three cocktail options needs roughly 120-160 servings if you're covering the full evening. Work backwards from there.
Single or double measures change both the cost and the pacing of your event. A single measure suits a long reception where guests will drink steadily for hours. Doubles work better for shorter, sharper celebrations where you want impact over duration.
Mix your selection across styles: something citrus-led, something spirit-forward, something lighter. A curated collection of three or four flavours keeps everyone happy without turning your order into a logistics puzzle.
Place your order at least three weeks before the event. That gives time for custom branding, personalisation and a delivery slot that isn't a panic.
For quantity:
| Event Size | Recommended Pack | Price | Best For |

| 20-30 guests | Go Big 6-Pack | £71.95 | Intimate parties, pre-drinks |

| 80+ guests | Go Biggest 24-Pack | £285.95 | Large weddings, big launches |

Personalised cocktail boxes have overtaken sugared almonds and printed coasters as the wedding favour guests actually take home. A single bottle with the couple's names and wedding date on the label does more than sit on a shelf. It gets opened, photographed and remembered.
Our wedding favours collection is built for exactly this. You choose the cocktail, we add the personalisation, and every guest leaves with something that tastes as good as it looks.
The practical benefit matters too. Favours that fit through a letterbox can be posted to guests who couldn't attend, which solves the awkward problem of leftover gifts after the big day.
Custom branded cocktail kits work for corporate gifting because they're consumed, not stored. A branded notebook gets filed away. A box of handcrafted cocktails gets opened that evening and shared, which means your brand is in the room long after the event ends.
For client thank-yous, a personalised box signals effort. For staff rewards, it signals a company that understands what people actually want at the end of a long quarter. Our corporate gifting range covers both, with options for individual gifts or bulk orders across a team.
Ordering in bulk for a client list or a full department is straightforward: send us your quantities, your branding requirements and your deadline, and we handle the rest.
Custom branding covers the label and the box itself. Company logos, event names, a short message from the host, or a QR code linking to a menu all work. The result is a kit that looks like it was made for your event, because it was.
There's a line worth respecting here. Branding should feel considered, not cluttered. One clean logo and a date beats five colours and a slogan fighting for space.
Most guides stop at "we deliver to your door". For an event, the delivery is the easy part. The hard part is making 200 boxes arrive in the right place, at the right time, in the right condition, without anyone chasing a courier on the morning of the wedding.
Here is how a large order actually works.
Every box is sized to fit through a standard letterbox, so nothing needs signing for and nothing gets taken back to a depot. That matters most when the venue is locked until the morning of the event and there is no one on site to accept a pallet.
For orders above roughly 100 boxes, splitting the delivery across two or three dates rather than one drop can be helpful. Confirm your delivery window at least a fortnight ahead. If the venue can accept parcels on your behalf, get that in writing from the venue coordinator, not just a verbal yes from the events team.
A five-minute call with the venue saves a lot of awkwardness later.
Sustainability is now a standard question from event planners, and venues increasingly ask for it in their supplier paperwork. Ask about three things before you order:
If your venue has a sustainability policy, ask for the packaging spec in writing so you can pass it on. It is a small step that avoids a last-minute scramble.

Pairing is where a good cocktail selection becomes a great one. The rule is simple: match intensity to the food and the mood, not to a rulebook. But the detail is where most event planners get stuck, so here is how to actually build the list.
Work backwards from the menu. A cocktail that tastes great on its own can clash badly with a main course, and a cocktail that seems plain on its own can lift a whole course.
The most common mistake with event drinks is over-ordering variety and under-ordering quantity. Guests drink more of two familiar favourites than they do of six unfamiliar options. Order deep on your bestsellers, not wide across the range.
A workable rule for most events:
If you are ordering a fully bespoke selection, tasting before you commit can be a good idea. Taste at the strength you plan to serve, not neat, because dilution changes the drink.
Before you confirm any order, run through this checklist:
What to avoid: leaving the order to the last fortnight, assuming a venue will store 40 boxes for you, and choosing flavours based on what looks good rather than what your guests will actually drink.
Bespoke cocktail boxes give every guest the same bar-quality drink. You can mix flavours across a single order, add company branding to the packaging, and have boxes delivered straight to an office, venue or each attendee's home. That makes them practical for large teams, remote workers and client gifts.
Yes. Personalisation usually covers names, dates, a short message or a monogram, and corporate orders can carry a company logo and brand colours. For weddings, many couples add the couple's names and the date to the box or bottle label so the favour doubles as a keepsake. Share your artwork or wording when you order and ask for a proof before printing starts.
For 40 guests or more, allow at least four to six weeks. That gives time for artwork proofs, flavour choices and a scheduled delivery window. Peak wedding season and December fill up fastest, so booking earlier is safer. If your date is close, ask what can be turned around quickly and whether the order can be split across two deliveries.
They do. Because the boxes are designed to fit through a standard letterbox, you can send them to individual home addresses rather than one venue. That suits virtual team events, hybrid celebrations and guests who cannot travel. Just confirm the delivery address list in advance and allow a few days for boxes to arrive before the event date.
Planning an event means juggling a hundred details, and the drinks shouldn't be one of them. Letterbox Cocktails delivers premium ready-to-drink cocktails through the letterbox, with build-your-own boxes, personalised wedding favours and custom branded corporate kits, all backed by UK-wide delivery and a five-star reputation. Get started with Letterbox Cocktails and give your guests a drinks experience they'll remember for the right reasons.
