When it comes to running a profitable hospitality business, every drop counts – literally. Wine wastage is one of the most overlooked drains on profit in bars, restaurants, and cellar doors. But once you know how to measure it – and how to stop it – you can turn lost revenue into serious gains. > *Even if you're only wasting half a glass per bottle, that can easily be over $28,000+ in wastage every year.* Wine wastage refers to any wine that’s bought but not sold. It might be: - Glasses left over from bottles that oxidised before they were finished - Staff over-pouring beyond your standard serve - Spoilage from poor storage (including refrigeration) - Tastings or comps not properly accounted for It may not feel like much day-to-day, but over the course of a year, wastage can add up to **tens of thousands of dollars** in lost profit — especially if you’re running a by-the-glass program. ### Calculate Your Wastage Instead of spreadsheets and guesswork, use our simple calculator to estimate how much you might be losing right now. ### Wine Wastage Calculator Adjust the below assumptions to reflect your venue. Number of by-the-glass wines Bottles opened each week Glasses per bottle Average glass sale price Average wastage (%) Weeks open per year Calculate wastage **Estimated revenue lost to wastage:** - $0 per week - $0 per month - $0 per year Typical wastage ranges from 10–20% due to over-pours, oxidation and comps. On average, 10% wastage would be half a glass per bottle opened, whereas 20% would be one glass per bottle opened. ### Why You Should Track Wine Wastage Most venues don’t actually track wastage, assuming it’s just part of doing business. But 10% is a conservative figure – and even at that level, you could be losing $1,000+ per month. Tracking wastage helps you: - See exactly where you’re leaking profit - Price your wine list more effectively - Hold your team accountable for accurate pours - Make smarter decisions about your wine program ### How to Track Wastage in Real Life We recommend starting with a one-month snapshot: 1. **Measure everything** – Track how many bottles were opened and how many glasses sold. Any discrepancy = wastage. 2. **Account for tastings and comps** – Record every pour so it’s intentional, not invisible. 3. **Note spoilage** – Bottles left open too long or improperly stored should be written down. (Tip: if a bottle is faulty, you may be able to return it to your distributor — just keep the bottle and notify them quickly.) 4. **Check for over-pours** – Know your standard pour size (150ml is the most common). Anything more = lost profit. At the end of the month, multiply your wastage in glasses by your average sale price to find your **real $ cost of wine wastage**. ### How Enomatic Eliminates Wine Wastage This is where technology pays for itself. Enomatic wine dispensing systems are designed to eliminate the most common causes of wastage: - **Precise portion control** – every pour exact, no more over-pours. - **Gas preservation** – keeps wine fresh for up to 30 days, so you sell the full bottle, not just the first few glasses. - **Temperature control** – prevents spoilage from poor storage. By switching to an Enomatic, many venues recover **tens of thousands in lost profit annually**. In most cases, the system pays for itself just by eliminating your first year's wastage. ![_A7R9875](https://www.winepreservationsystems.com/hs-fs/hubfs/_A7R9875.jpg?width=2560&height=1707&name=_A7R9875.jpg) ### Next Step: See How Quickly an Enomatic Pays Itself Off We’ve created a free **By-the-Glass Profit Planner** to help you: - Calculate weekly gross profit - Track your average wastage - See how quickly an Enomatic system could pay for itself ### Get Your By-The-Glass Profit Planner   ## Share this post [mailto:https%3A%2F%2Fwww.winepreservationsystems.com%2Fblog%2Fwine-wastage-cost](mailto:https%3A%2F%2Fwww.winepreservationsystems.com%2Fblog%2Fwine-wastage-cost) ## Keep reading ### [![](https://www.winepreservationsystems.com/hs-fs/hubfs/Wine-Preservation-Systems_Edit_2026-07-22_1x%20(2).jpg?width=2304&height=1728&name=Wine-Preservation-Systems_Edit_2026-07-22_1x%20(2).jpg) How to Trial a Wine Preservation System Before You Buy](https://www.winepreservationsystems.com/blog/trials) ### [![](https://www.winepreservationsystems.com/hs-fs/hubfs/AI-Generated%20Media/Images/Le%20Verre%20de%20Vin%20Tower%20on%20Bar%20Counter.png?width=1536&height=1024&name=Le%20Verre%20de%20Vin%20Tower%20on%20Bar%20Counter.png) Why We're Now Wine Preservation Systems](https://www.winepreservationsystems.com/blog/wine-preservation-systems-new-name) ![Wine Preservation Systems white](https://www.winepreservationsystems.com/hubfs/Wine%20Preservation%20Systems%20white.png "Wine Preservation Systems white") **FREE RESOURCES** [Map of current installs](https://maps.app.goo.gl/MHRiKBvyNpyXmkn26) [Enomatic vs. Coravin](https://winepouringsystems.com/blog/enomatic-coravin) [Pricing Bottle Shop Tastings](https://winepouringsystems.com/blog/bottle-shop-tastings) [Pricing Wine Lists](https://winepouringsystems.com/blog/price-by-the-glass-wine-list) [How to Calculate Wastage](https://winepouringsystems.com/blog/wine-wastage-cost) [On-Demand Webinar](https://winepouringsystems.com/webinar) **ENOMATIC** [Unica Roma](https://winepouringsystems.com/unica) [Unica Start](https://winepouringsystems.com/unica-start) [Unica Bubbles](https://winepouringsystems.com/unica-bubbles) [Unica Bag](https://winepouringsystems.com/unica-bag) **BERMAR** [Tower](https://www.winepreservationsystems.com/lvdv-tower) [Compact](https://www.winepreservationsystems.com/lvdv-compact) [Classic](https://www.winepreservationsystems.com/lvdv-classic) **ABOUT** [Contact Us](https://winepouringsystems.com/contact) [About Us](https://winepouringsystems.com/about) [FAQs](https://winepouringsystems.com/knowledge-base/overview) [Financing](https://winepouringsystems.com/financing) [Resellers](https://winepouringsystems.com/reseller-request) **CUSTOMERS** [Knowledge Base](https://winepouringsystems.com/knowledge-base/maintenance) [Support Request](https://winepouringsystems.com/support-request) [Order new stoppers](https://bermar.com.au/shop/) [mailto:info@winepouringsystems.com](mailto:info@winepouringsystems.com) © 2026.
