While most restaurant owners obsess over food costs, the real profit opportunity sits in your bar program. Drinks deliver substantially lower cost percentages than food - typical pour costs hover around 20% versus food costs of 30-35%. Each additional drink per guest directly amplifies your table margins.
Why drinks are so important for your margin
Drinks function as your restaurant's profit engine. That €6.50 glass of wine costs you just €1.30 to pour - a clean 20% cost ratio. Meanwhile, your main course at 32% food cost generates proportionally less profit.
- Average pour cost alcohol: 18-25%
- Average restaurant food cost: 28-35%
- Difference: 10-15 percentage points more margin on drinks
💡 Example:
Table of 4 people, average bill €120:
- Scenario A: €80 food + €40 drinks
- Scenario B: €60 food + €60 drinks
Difference in margin: €4.80 extra profit per table!
Calculate your current drink-food ratio
You can't improve what you don't measure. Pull these numbers from your POS system for the last 30 days:
- Total food sales (excl. VAT)
- Total drink sales (excl. VAT)
- Number of covers (guests)
Then run these calculations:
- Average food per guest = Food sales / Number of guests
- Average drinks per guest = Drink sales / Number of guests
- Drink-food ratio = (Drink sales / Food sales) × 100
💡 Example calculation:
- Food sales: €45,000
- Drink sales: €18,000
- Number of guests: 1,500
Average food per guest: €30
Average drinks per guest: €12
Drink-food ratio: 40%
Calculate the impact of increased drink consumption
Here's where the math gets exciting. Use this formula to project your additional profit:
Extra margin = (Extra drinks per guest × Number of guests × Working days) × (100% - Pour cost%)
⚠️ Note:
Calculate with prices excl. VAT. Alcoholic drinks carry 21% VAT, so that €6.00 wine actually rings up as €4.96 excl. VAT.
💡 Example impact:
Current drinks per guest: €12 excl. VAT
Target: €16 per guest (+€4)
- Extra per guest: €4
- Pour cost: 22%
- Margin on extra drinks: 78%
- Extra margin per guest: €4 × 0.78 = €3.12
At 100 guests/week: €3.12 × 100 × 52 = €16,224 extra per year
Strategies to increase drink consumption
Now that you've crunched the numbers, here's how to boost those drink sales systematically. This is a pattern we see repeatedly in restaurant financials - places that nail these tactics consistently outperform on margins:
- Wine-food pairings: Train staff to suggest specific wines with each dish
- Aperitif routine: Make pre-meal drinks part of your standard greeting
- Digestif suggestion: Offer liqueurs or dessert wines after the main course
- Carafe wines: Encourage sharing with half and full carafes
Monitor your results
Track your progress every 30 days. Focus on these key metrics:
- Average drinks per guest (should climb steadily)
- Drink-food ratio (target 50-60%)
- Total margin per table
Systems like tools like KitchenNmbrs can automate this tracking and show you which tactics deliver the biggest profitability boost.
How do you calculate the margin impact? (step by step)
Gather your current figures
Pull from your POS system: total food sales, drink sales and number of guests from last month. Convert everything to excl. VAT (food ÷ 1.09 and drinks ÷ 1.21).
Calculate averages per guest
Divide food sales by number of guests and drink sales by number of guests. This gives you current average food and drinks per person.
Set a realistic target
Increase your drink target by 20-30% (for example from €12 to €16 per guest). Calculate the difference and multiply by (100% - pour cost%) for the extra margin.
✨ Pro tip
Track your top 10% of servers' drink attachment rates over the next 6 weeks. You'll likely find they're suggesting wine pairings 3x more often than your average staff - then train everyone on their techniques.

Frequently asked questions
What is a good drink-food ratio?
A healthy ratio falls between 40-60%. Restaurants with strong beverage programs typically hit 50-60%, where drink sales equal half of food sales. Anything below 35% suggests missed profit opportunities.
How do I calculate the pour cost of my drinks?
Pour cost = (purchase price / selling price excl. VAT) × 100. So that €8 bottle of wine you sell for €40 excl. VAT delivers a 20% pour cost.
Should I include VAT in my calculation?
Always calculate excluding VAT for accuracy. Alcoholic drinks carry 21% VAT while food gets 9%, so including VAT skews your comparisons with purchase costs.
How often should I check these figures?
Review your drinks per guest and drink-food ratio monthly. This frequency lets you spot trends quickly and adjust tactics before problems compound.
