A busy Dublin pub discovered they were losing €18,000 annually just from bartenders pouring an extra 8ml of gin per cocktail. Many bars hemorrhage money through generous pours without realizing the true cost. Standardized pour sizes can increase your bar profit by 15-25%.
Why standardized pour sizes matter
Drinks are all about milliliters. A few extra ml per drink seems insignificant, but it compounds dramatically. A standard gin and tonic uses 50ml gin. Your bartender pours 60ml? You've just lost 20% of your margin.
⚠️ Note:
Alcohol has 21% VAT, not 9%. Always calculate with the price excluding VAT for your pour cost calculation.
The basic savings formula
Your calculation needs three components:
- Current pour volume - what you're actually pouring now
- Standardized volume - what you should be pouring
- Difference per drink - your savings per glass
The formula: Annual savings = Difference per drink × Number of drinks × 365 days
💡 Example gin and tonic:
You sell 40 gin and tonics per day at €8.50 (incl. 21% VAT)
- Current pour volume: 60ml gin
- Standardized: 50ml gin
- Difference: 10ml per drink
- Gin costs €25 per liter = €0.025 per ml
Savings: 10ml × €0.025 × 40 drinks × 365 days = €3,650 per year
Measure your current pour volumes
You can't calculate what you don't measure. Track your actual pours for a full week:
- Let bartenders pour normally
- Measure 10 drinks per type with a measuring cup
- Calculate the average pour volume
- Compare with your target pours
Most bars are stunned by the results - something most kitchen managers discover too late after months of wondering why beverage costs stay high. Differences of 20-30% aren't uncommon.
Calculate the impact per drink type
Not all drinks affect your bottom line equally. Target your most expensive and popular drinks first:
💡 Priority list:
- Premium spirits: Biggest impact due to high cost price
- Popular cocktails: High volume means every ml counts
- Wine by the glass: 150ml vs 180ml creates €1+ difference per glass
- Beer: Lower impact, but still relevant at high volumes
Calculate annual savings
For a complete picture, add up all drink types. Use this formula per drink category:
Savings = (Current volume - Standard volume) × Price per ml × Number per day × 365
💡 Complete bar calculation:
Average bar with 150 drinks per day:
- Gin and tonics: €3,650 savings per year
- Whiskey neat: €2,800 savings per year
- Wine by the glass: €4,200 savings per year
- Other cocktails: €2,100 savings per year
Total savings: €12,750 per year
Calculate pour cost improvement
Standardized pour sizes directly improve your pour cost - the percentage of your drink price spent on ingredients. It's the beverage equivalent of food cost.
Standard pour cost for alcohol runs 18-25%. With standardized measures you can often improve this by 3-5 percentage points.
⚠️ Note:
Always calculate pour cost with the drink price excluding 21% VAT. A gin and tonic of €8.50 incl. VAT is €7.02 excl. VAT.
Implementation and control
You only realize savings through consistent execution:
- Make measuring cups mandatory for all spirits
- Mark wine measures on glasses
- Check weekly by measuring volumes
- Train your team on why measures matter
Systems like KitchenNmbrs let you record drink recipes with exact volumes and automatically calculate pour cost per drink.
How do you calculate the savings? (step by step)
Measure current pour volumes
Let bartenders pour normally for a week and measure 10 drinks per type with a measuring cup. Calculate the average volume per drink type and compare with desired standard measures.
Calculate difference per drink
Subtract the desired volume from the measured volume. Multiply this difference by the price per ml of your alcohol. This gives you the savings per individual drink.
Calculate on an annual basis
Multiply the savings per drink by the number of drinks per day and by 365 days. Add up all drink types for your total annual savings from standardized pour sizes.
✨ Pro tip
Track your top 3 spirit-based cocktails for exactly 7 days - this captures weekend vs weekday variations and gives you 70% of your potential savings data. Most bars see the biggest pour inconsistencies during busy Friday nights.

Frequently asked questions
How much can I realistically save with standardized pour sizes?
An average improvement of 15-25% of your bar profit is achievable. For a bar with €200,000 annual drink revenue, this means €8,000-€15,000 extra profit per year.
What are standard pour sizes for popular drinks?
Gin/vodka: 50ml, whiskey neat: 35ml, wine by the glass: 150ml, cocktails: follow the recipe exactly. These measures provide a good balance between taste and profitability.
Which drinks have the biggest impact when standardizing?
Premium spirits and popular cocktails first. A 10ml difference with premium gin at €40/liter has more impact than beer. Focus on your most expensive and best-selling drinks.
