Use this guide to check the assumptions, then open the wedding alcohol calculator with your own figures.
Ask before buying
Venue rules can change what you are allowed to bring, serve, return, or store.
- Is outside alcohol allowed?
- Is there corkage or a licensed bartender requirement?
- Can unopened bottles be returned or removed after the event?
Plan the non-alcohol items
The alcohol estimate is only one part of the bar setup.
- Water and soft drinks.
- Ice, cups, glassware, and napkins.
- Mixers, garnishes, and alcohol-free alternatives.
Wedding alcohol buffer and return policy planning
A buffer is more useful when returns are allowed or the venue is hard to restock during the event.
Match the buffer to the risk
The calculator includes a default buffer, but the right order depends on how easy it is to return, store, or restock drinks.
- Use a smaller buffer when unopened returns are not allowed.
- Use a larger buffer when the venue is remote and returns are possible.
- Ask suppliers about case minimums before finalizing the order.
Keep the estimate separate from service rules
Quantity is only one part of a wedding bar plan. Venue rules and local alcohol laws decide what can be served and by whom.
- Confirm corkage, licensing, and bartender requirements.
- Check storage and chilling arrangements before delivery.
- Do not use the estimate to encourage overconsumption.
Buffer decision checks
The buffer decision checks reference keeps the relevant comparisons together so each assumption can be checked before changing the calculator inputs.
- Situation: Returns allowed; Buffer impact: Larger buffer is less risky; Question to ask: What unopened items qualify?
- Situation: Remote venue; Buffer impact: Running short is harder; Question to ask: Can anyone restock safely?
- Situation: No returns; Buffer impact: Tighter order may be better; Question to ask: What minimum cases are required?
Wedding alcohol case sizes and rounding guide
The calculator rounds bottles, but suppliers may require cases, minimums, or sale-or-return terms.
Bottle counts are not always order counts
The calculator returns practical bottle and can counts, but suppliers may sell by case, keg, crate, or mixed case. Convert the result into supplier order units before buying.
- Check wine case size before rounding the final order.
- Check beer pack size, keg size, or can count.
- Ask whether unopened cases or bottles can be returned.
Return rules change the buffer
A generous buffer is easier to justify when unopened returns are allowed. If returns are not allowed, tighten the order and make sure water and alcohol-free options are still well planned.
- Write down return deadlines and conditions.
- Keep receipts and unopened cases together.
- Confirm who takes leftover alcohol after the event.
Supplier rounding checks
The supplier rounding checks reference keeps the relevant comparisons together so each assumption can be checked before changing the calculator inputs.
- Item: Wine; Calculator gives: Bottle count; Supplier may require: Cases of 6 or 12.
- Item: Beer; Calculator gives: Bottles or cans; Supplier may require: Packs, crates, or kegs.
- Item: Spirits; Calculator gives: 750 ml bottles; Supplier may require: Brand-specific bottle sizes.
Venue questions
| Question | Why it matters | Where to confirm |
|---|---|---|
| Can we bring alcohol? | Affects whether buying your own is possible. | Venue contract or coordinator. |
| Who serves it? | May require licensed staff. | Venue or caterer. |
| Can we return extras? | Changes how large a buffer is sensible. | Retailer or supplier. |
