Most restaurant owners think wine turnover is just about how fast bottles sell. But it's actually about cash flow - slow turnover locks up your money in dusty bottles while fast turnover means you're losing sales from empty shelves. Finding the sweet spot keeps your wine program profitable.
What is wine turnover?
Turnover (also called 'stock turnover') shows how many times your entire wine inventory sells and gets replaced annually. A turnover of 6 means you cycle through your complete wine stock 6 times yearly - that's every 2 months.
💡 Example:
Restaurant with wine cellar:
- Annual wine sales: €120,000
- Average inventory value: €20,000
- Turnover: €120,000 ÷ €20,000 = 6
Your wine inventory renews 6 times per year.
The formula for turnover
Turnover = Annual wine sales (purchase price) ÷ Average inventory value
Remember: use the purchase price of sold wine, not selling price. You can't mix purchase costs with retail values.
⚠️ Important:
Always calculate using purchase price of sold wine, not selling price. Mixing these creates meaningless numbers.
Calculate step by step
Step 1: Gather your wine sales (purchase price)
Total all wine sold this year at what you paid for it. Example: you sold €80,000 worth of wine (selling price), but your purchase cost was €32,000.
Step 2: Calculate your average inventory value
Add January 1st and December 31st inventory values, then divide by 2. Monthly counts divided by 12 give better accuracy.
Step 3: Divide sales by inventory
€32,000 (sold at purchase price) ÷ €8,000 (average inventory) = 4. Your wine turns over 4 times yearly.
💡 Real-world example:
Bistro with 40 wine selections:
- Wine sales (purchase): €28,000
- Inventory start of year: €6,000
- Inventory end of year: €8,000
- Average inventory: €7,000
Turnover: €28,000 ÷ €7,000 = 4
What do the numbers mean?
Typical turnover rates in restaurants:
- 2-4 turnover per year: Sluggish. You might have excess inventory or poor wine selection
- 4-8 turnover per year: Solid. Good balance between variety and movement
- 8+ turnover per year: Rapid. You could be losing sales from limited options
Poor turnover ties up cash in bottles that collect dust. Excessive turnover suggests you're missing revenue from stockouts. I've seen this mistake cost the average restaurant EUR 200-400 per month in lost profits and tied-up capital.
⚠️ Important:
Premium wines move slower than house pours. Calculate by price tier for clearer insights.
Improving your turnover
If your turnover is too low (under 4):
- Identify your slowest-moving bottles
- Swap poor performers for proven sellers
- Coach staff on wine recommendations
- Host wine events to boost interest
If your turnover is too high (above 10):
- Broaden your selection within each price range
- Include premium options for better margins
- Verify you're ordering enough popular wines
💡 Practical tip:
Monitor your top 10 wine sellers:
- If these represent 80% of wine sales: your selection works
- If sales spread evenly: you might have too many options
Turnover by wine type
Different wines move at different speeds:
- House wine by glass: 15-30 turnover yearly (reorder weekly)
- Mid-range bottles €20-40: 8-15 turnover yearly
- Premium wines €40+: 2-6 turnover yearly
- Sparkling wines: 6-12 turnover yearly (seasonal spikes)
Tools like KitchenNmbrs track wine sales and inventory values automatically, eliminating manual counting.
How do you calculate wine turnover? (step by step)
Gather your wine sales (purchase price)
Add up all the wine you sold this year, but at purchase price. If you sold €100,000 in wine at selling price, and your purchase price was on average 40%, then this is €40,000. Use your POS system or invoices to find this.
Calculate your average wine inventory
Add up your wine inventory at the beginning and end of the year, divide by 2. For more precision: count each month and divide by 12. Calculate using purchase price of wines in your cellar, not selling price.
Divide sales by average inventory
Turnover = Annual wine sales (purchase) ÷ Average inventory value. A result of 6 means your wine inventory turns over 6 times per year, in other words completely renews every 2 months.
✨ Pro tip
Track your wine-by-the-glass turnover weekly rather than annually - aim for 2-3 complete bottle turnovers per week to ensure freshness. Opened bottles that sit longer than 5 days hurt quality and profits.

Frequently asked questions
What counts as healthy wine turnover?
Most restaurants see 4-8 annual turns as optimal. House wines move much faster at 15-30x yearly, while premium bottles turn 2-6x. Your concept and price points determine what's normal.
Should I use purchase price or selling price?
Always purchase price for both sales and inventory calculations. Mixing purchase costs with retail prices creates meaningless comparisons. Your balance sheet shows inventory at cost anyway.
Why do my expensive wines barely turn over?
Premium wines naturally sell less frequently than house pours. Turnover of 2-4 yearly is typical for bottles over €50. Focus on total wine profit margins, not just turnover speed.
How frequently should I track turnover?
Monthly tracking catches trends early and allows quick adjustments. Quarterly is the minimum for useful data. Seasonal businesses especially need monthly monitoring to optimize inventory timing.
What should I do about slow-moving inventory?
First, identify your worst performers and replace them with proven sellers. Train staff on wine sales techniques and consider wine tastings to generate buzz. Sometimes you simply have too much stock for your sales volume.
Can I calculate turnover for wine categories separately?
Absolutely - and you should. Break down by house wines, mid-range bottles, and premium selections to see exactly where inventory moves too slowly or quickly. Each category has different optimal turnover rates.
