How to Build a By-the-Glass Wine Program That Actually Makes Money

A well-run by-the-glass wine program is one of the most profitable things a restaurant or bar can do with its wine list. It brings in guests who aren't ready to commit to a bottle, encourages exploration, and – when done right – increases wine revenue per head significantly.

But a by-the-glass program only makes money if you manage it properly. Open bottles left to oxidise, staff who can't speak to the list, and pricing that ignores your cost structure will turn a great concept into a slow bleed.

Here's how to build one that works.

1. Start with eight wines, not twenty

More options don't mean more sales. A by-the-glass program of eight wines, chosen thoughtfully, will outperform a list of twenty that no one can speak to.

A solid eight-wine spread might include: a refreshing white, a fuller white, a rosé, a lighter red, a bolder red, a sparkling option, and one or two wildcards – a skin-contact, a lesser-known variety, something to start a conversation. Rotate the wildcards regularly. Regulars notice, and it gives your staff something new to talk about.

2. Solve the preservation problem

The number one reason by-the-glass programs underperform is waste. An open bottle degrades from the moment you open it – depending on the variety, you might have a day, maybe two, before it's not worth serving.

Wine preservation systems that use inert high-purity argon gas change this entirely. Kept under argon, wines stay fresh for weeks. You can open a bottle on a quiet Tuesday and serve the last glass next Saturday without any loss in quality.

Without preservation, you're either limiting your range or writing off bottles. Neither is a good business model.

3. Lock in your margins with calibrated pours

The best wine dispensing systems protect your margins through calibrated pour sizes. Every glass is the same, every time. No over-pouring at the end of a busy shift. No variance between staff.

The wine profit margin you calculate on paper is the one you actually make. This is the part most operators overlook until they run the numbers and realise how much they've been losing to inconsistent pours. Wastage is not just about oxidation.
