What’s the Winemaker’s Think Tank? 

Every Thursday we will post about a few frequently asked questions that our winemaker has answered. If you have a winemaking question you would like to have answered, please email us at support@juicegrape.com and we will try to get into next week’s post. Cheers! 🙂

What is the best way to sanitize my equipment?

It is important to differentiate between cleaning, sanitizing, and sterilizing. Cleaning is removing any dirt, grape debris, or build-up from your equipment. Sterilizing is the process via heat or chemicals of eliminating all micro-organisms, which is nearly impossible in a home winemaking environment. Sanitizing is the goal for home winemakers. Sanitizing is the removal of harmful micro-organisms from the winemaking equipment. This will give the winemaker the healthiest environment possible for their wine. One of the most chemically and cost effective ways to sanitize winemaking equipment is by using potassium metabisulfite. Potassium metabisulfite works best in an acidic environment. To create a strong sanitizing solution, mix 2 tbsp. of citric acid and 1 tbsp. of potassium metabisulfite with 5 gallons of warm water. Mix all of these in a 6 gallon pail. You can now use this solution to sanitize all of your equipment. Submerge or rinse all of the equipment in this solution. This solution will sanitize the equipment of any harmful bacteria that could spoil the wine. Any tool, vessel, or hose that touches the wine should be rinsed thoroughly with the solution to prohibit contamination.
