In this article
Every independent restaurant with a wine list longer than one page eventually asks this: hire a sommelier, send someone on a course, or just let whoever's free that night make the call — "something red, medium-bodied"? Almost nowhere is this treated as a number instead of a gut feeling. Restaurants either splash out on a full-time sommelier they can't yet support, or never invest at all and leave wine margin on the table forever. This article treats it as a genuine three-tier decision with a real floor below which neither tier pays for itself yet — the same honest "sometimes the answer is no" the cash-flow planner and the ambiance tool already model, rather than a sales pitch for hiring.
This isn't about building the list or giving pairings
How to put together a wine list that actually works, how to give confident wine recommendations at the table, how to pair wine with food, and how to manage a wine cellar without capital sitting idle for years — those four articles all assume somebody is already doing that work. This article asks the question that comes before all of them: who should that be, and is it worth paying for? Not as a matter of taste, but as arithmetic.
Number 1: the wine gross-profit gap you already have
A well-run wine list keeps its cost-% — the wholesale price of the bottle divided by what you charge for it, ex VAT — inside a target band of 25 to 33%. That figure isn't invented for this piece: it is the exact band this site already established for the wine line in its pour-cost and beverage-margin analysis, and this article deliberately reuses it rather than re-deriving a conflicting one — one band, two articles, one number.
A wine list with no owner rarely drifts downward. Without someone actively managing pricing, buying and the by-the-glass programme, cost-% creeps upward: a supplier raises the wholesale price and nobody adjusts the list, a bottle gets priced too cautiously out of fear it won't sell, or the by-the-glass selection never rotates with what's already open anyway. At most restaurants with no one assigned to it, wine cost-% sits 3 to 8 points above that target band.
| Figure | Value |
|---|---|
| Target wine cost-% (well-run list) | 25–33% |
| Example: your current wine cost-% | 38% |
| Gap above the top of the band | 5 percentage points |
| At €6,500 wine revenue/month, that's | €325/month |
Work this out for your own restaurant: take last month's wine revenue, multiply by however many points you sit above 33%, and divide by a hundred. That amount is margin that already exists today — no extra sales required, just the list, the buying and the pricing brought back inside the band. That figure is the foundation for everything that follows: it's the first money a trained staff member or a sommelier recovers, before a single extra bottle is sold.
Why wine drifts, and food doesn't
Food cost stays inside a narrow band thanks to recipes and portioning. Wine has no equivalent mechanism — unless somebody makes it their job.
The food-cost band comes from this site's own restaurant benchmark; the wine target band from the pour-cost and beverage-margin analysis. The third bar — a wine list with no owner — is this article's own working assumption, based on how much further a wine cost-% can drift than a recipe-priced dish: there's no portion or recipe control holding it back automatically.
Number 2: the break-even to train someone
The cheapest move isn't hiring — it's training someone already on staff. A WSET-style course (Level 1 or 2) is a one-off cost of around €900, and it's reasonable to give that person a modest wage bump afterwards — €150/month is typical once someone is genuinely responsible for the list. Spread the course cost over 24 months and you get a fixed monthly cost.
| Cost item | Amount |
|---|---|
| Course (one-off, WSET-style Level 1/2) | €900 |
| Spread over 24 months | €37.50/month |
| Ongoing wage bump | €150/month |
| Total monthly cost | €187.50/month |
Subtract the money from number 1 — the margin you're already leaving on the table by sitting above the target band. In the example above that's €325/month, comfortably more than the €187.50 training costs. In other words: at most restaurants with a real cost-% gap, training already pays for itself just from fixing the list — no extra revenue required at all. That's the figure most owners miss, because they assume training only pays off if wine revenue actually grows.
Number 3: the break-even to hire a sommelier
A full-time sommelier or dedicated wine steward is a different order of magnitude: budget around €3,200/month in full cost, including employer overhead — for someone who fully owns the list, the buying, the cellar and the advice at the table. That's nearly 17 times the monthly cost of training, and that gap is exactly why the two options don't deserve the same answer.
| Cost item | Amount |
|---|---|
| Gross salary, full-time sommelier | €2,300–2,600/month |
| Employer overhead (varies by country) | €600–900/month |
| Full monthly cost | ≈ €3,200/month |
Subtract number 1's money here too. In the example, €2,875/month remains to come from new wine revenue — not a cost-% correction, but genuinely more bottles and glasses sold. At a margin of 62% (100% minus the current 38% cost-%), that's about €4,637/month in extra wine revenue, on top of what you already do. Compare that with number 2 and the gap between "train" and "hire" becomes tangible: one asks you to fix your list, the other asks your wine revenue to grow by tens of percent.
The three rungs of the ladder
Cost per month against the extra wine revenue needed to cover it — on top of whatever the cost-% gap already recovers
No new cost — but the cost-% gap of €325/month just sits there.
Already covered by the cost-% gap — no extra wine revenue needed.
Needs +€4,637/month in extra wine revenue, on top of what the gap covers.
Based on the worked example above: €6,500/month wine revenue, 38% wine cost-%, a target band of 25–33%. Plug in your own figures with the calculator below.
Work out your own break-even point
Enter your own wine revenue, cost-%, course cost, wage bump and sommelier salary, and see instantly how much money your current list is already leaving on the table, how much extra wine revenue training or hiring would need, and where the floor sits below which neither one pays for itself yet.

All amounts are indicative — enter your own figures
The calculator above follows exactly the logic of numbers 1 through 3: first the cost-% gap is credited as money you already have, and only what's left afterwards gets converted into the extra wine revenue that's actually needed. As a rule of thumb, the tool uses: training is realistic if the extra revenue needed stays under 20% of current wine revenue, hiring under 35%; above 50% the jump is too large to make this year, and that's exactly the floor from number 4.
Number 4: the floor — when neither one pays off
With the figures above, the floor sits at roughly €521 in monthly wine revenue: €187.50 ÷ (5% + 50% × 62%) ≈ €521. Below that level, even the cheapest move — training someone — needs wine revenue to grow by more than half, and that isn't a realistic jump for one course and one wage bump. That's the figure most sommelier pitches never mention: they quietly assume there's already enough wine revenue to build on.
A restaurant below the floor
Take a restaurant doing €500/month in wine — a short list, mostly there to tick a box. At the same 38% cost-%, the gap against the target band only recovers €25/month. To cover the €187.50 that training costs, wine revenue would need to grow by more than half — 52%, to be exact. That's not impossible, but it isn't an investment decision any more, it's a growth target. The honest move there isn't "train someone," it's growing wine revenue first — a wider by-the-glass offer, a list that's less overwhelming, a team that consistently asks one question at the table — and only then running this arithmetic again.
Above the floor: the question becomes real
Once wine revenue clears the floor — as in the main example, where €6,500/month sits comfortably above the €521 — training is almost always defensible, and hiring becomes a question of how much further wine revenue can realistically grow. That's the real conversation: not "can we afford it," but "how much extra wine revenue is realistic, and does that cover the jump from number 3."
Action plan
This week: calculate your own wine cost-% (wholesale cost of wine sold divided by wine revenue, ex VAT) and compare it against the 25–33% target band. Enter your own figures into the calculator above.
This month: if you're above the target band, start with the cost-% correction from number 1 — that money immediately funds (part of) training. Get a quote for a WSET-style course in your country and decide who's a fit for it.
This quarter: if you're below the floor from number 4, use the revenue simulator or the covers forecast to see how much extra covers or a wider by-the-glass offer could realistically add to your wine revenue, before running this decision again. If you're above it, use the staff-cost calculator to work out the full cost of a sommelier for your own country — the €3,200 above is an EU average, not an exact figure for your situation.
Conclusion
The sommelier decision isn't a matter of taste or a status symbol — it's arithmetic with three possible answers and an honest fourth: sometimes the answer is neither, not yet. Most restaurants with a wine list worth having already pay for training without knowing it, just by fixing the list and the prices. Hiring is a different decision, one that genuinely needs revenue to grow. And below a certain revenue level, the honest move is neither — it's making sure there's enough wine revenue to make this arithmetic worthwhile in the first place.
