How to Split a BYOB Restaurant Bill

BYOB (bring your own bottle) restaurants solve one problem — alcohol markups — and introduce another: everyone showed up with different wine, some people shared their bottle generously and others did not, the corkage fee applies to some bottles and not others, and now someone has to split a food-only bill while mentally accounting for whose wine went where.

Here is how to handle the BYOB dining bill cleanly.

The Food-Only Split: The Easy Part

At a BYOB restaurant, the restaurant's bill typically contains only food items (and non-alcoholic beverages if anyone ordered them). The wine cost is not on the bill — people covered it when they bought their bottles.

For the food portion of the bill, use whatever split method makes sense for the group:

• Equal split: everyone ordered similarly priced food, so divide the food total equally.
• Itemized split: orders varied significantly; each person pays for what they ordered.

This is often simpler than a full-service restaurant bill because the alcohol complexity is removed. The food-only receipt is cleaner and faster to split.

Corkage Fees

Some BYOB restaurants charge a corkage fee — typically $5-20 per bottle opened — to cover the service of opening, decanting, and pouring. This fee appears on the restaurant bill.

Corkage fees should be assigned to the person whose bottle generated them. If each couple or individual brought their own bottle, each pays their own corkage fee. If the group brought one or two bottles to share, the corkage fee splits among the people who shared that wine.

When using Jig to split a BYOB bill, the corkage fee line items can be assigned to the relevant individuals just like any other line item on the receipt.

Who Brought What Wine

The wine-sharing dynamic at a BYOB dinner can get socially complex. Common scenarios:

• Each couple/person brought their own bottle and drank it themselves. Clean and simple: each person or couple is responsible for their own wine cost (paid at the store) and their own corkage fee. No cross-accounting needed.
• The group brought 2-3 bottles to share communally. Each person who brought a bottle spent real money on it. The fairest approach: each bottle's cost is split equally among everyone who drank from it. If you brought a $25 bottle and four people drank from it, each person effectively owes you $6.25 for your bottle.
• One person brought a very expensive bottle, others brought cheap wine. This is the trickiest scenario. If the expensive bottle was shared with everyone, there is an argument that the other participants should contribute to its cost, since they benefited. If the person with the expensive bottle intended it as their personal treat for the group, they may not want reimbursement. Clarify before opening.

When People Did Not Bring Wine

Some people at a BYOB dinner may not have brought wine — they had a soft drink or water, or they drank sparingly from others' bottles as a courtesy pour. These people should not be expected to contribute to others' wine costs unless they drank meaningfully from the bottle.

A general rule: if someone had one courtesy pour (half a glass), asking them to split the bottle cost is excessive. If they drank freely from your bottle throughout the meal, a contribution is reasonable.

Tip at a BYOB Restaurant

Tip at BYOB restaurants presents a nuanced question. Since the restaurant is not selling alcohol, the bill is lower and the standard tip percentage applied to the total will generate a lower tip than the server might get at a comparable full-service restaurant.

Standard guidance: tip at least 20% of the food bill. Some diners tip slightly higher at BYOB restaurants to compensate for the lower total, acknowledging that the server's work is similar to a full-service night out. This is a judgment call, but it is worth being generous.

If a corkage service was provided — someone opened and decanted your wine, kept glasses filled — recognize that service in your tip calculation.

A Practical BYOB Split Workflow

1. Restaurant bill split: photograph the food receipt with Jig, assign food items to individuals or split equally, assign corkage fees to relevant people.
2. Wine cost accounting: if bottles were shared, note who brought each bottle and what it cost. Split each bottle's cost among those who drank from it. This calculation happens outside the restaurant bill.
3. Settle both: use Venmo for the restaurant split (handled via Jig) and a separate calculation or rounding-up for the wine sharing.

The Bottom Line

BYOB restaurants produce a simpler restaurant bill (food only) with a parallel wine accounting question. Handle the restaurant bill with a standard itemized or equal split. Handle wine sharing separately: each person who brought a bottle recovers their cost from the people who drank it, and corkage fees go to the people whose bottles generated them.

For the food portion, Jig handles the receipt split in about a minute. For the wine accounting, a quick mental tally or Venmo request handles the rest.
