Keeping your Coravin Timeless Wine by-the-glass system clean is one of the easiest ways to protect every pour. Greg, Coravin's founder and inventor, shares his go-to maintenance tip to keep things running at their best.
Why Cleaning Matters
Unlike a corkscrew, your Coravin system makes direct contact with wine. Over time, residue can build up inside — and that can affect the taste of the wine you're preserving. A quick clean after each use keeps your system free of buildup and ready to pour wine exactly as the winemaker intended.
Simple Cleaning Steps
- Rinse After Use: At the end of every session, hold your Coravin system under the faucet and run hot water through the spout and precision-engineered needle. This clears any wine residue from the valve and needle – simple and effective.
- Deep Clean for Older Systems: If your system hasn't been cleaned in a while, give it a deeper clean. Pour a small amount of inexpensive vodka through the spout to break down any buildup inside. It's a straightforward step that helps maintain long-term performance.
Pro Tip
Make rinsing part of your end-of-night routine. The more consistently you clean your system, the better every pour will taste.
Deep Cleaning with Sodium Percarbonate
For a more thorough clean – particularly if your system has been stored or used heavily — 100% sodium percarbonate is an effective option. It's the active ingredient in oxygen-based cleaners and breaks down residue without leaving any chemical trace behind.
What to look for: Always use a product that is 100% sodium percarbonate with no added agents, fragrances, or additives. We've tested OneStep and The Malt Miller 100% Sodium Percarbonate — any other product with the same pure formulation should perform consistently, but remains untested by Coravin.
