\ud83e\udded Step-by-Step Wine Fermentation Process<\/h2>\n\n\n\nStep 1: Prepare and Clean the Tank<\/strong><\/h3>\n\n\n\nCleanliness is the foundation of a successful fermentation.
Like a cold brew system, any residue, mineral film, or microbial contamination will affect product clarity and taste.<\/p>\n\n\n\n
Best Practices:<\/strong><\/p>\n\n\n\n\n- Rinse the tank with hot water to remove visible residues.<\/li>\n\n\n\n
- Perform CIP (Clean-in-Place) with alkaline detergent followed by acid neutralization.<\/li>\n\n\n\n
- Passivate the stainless surface using citric or nitric acid to rebuild the protective oxide layer and prevent corrosion.<\/li>\n\n\n\n
- Pre-chill or pre-heat the cooling jacket to the starting temperature before filling.<\/li>\n<\/ul>\n\n\n\n
Step 2: Fill the Must or Juice<\/strong><\/h3>\n\n\n\nWhen the tank is spotless and temperature-ready, it\u2019s time to fill the grape must or juice.
Stainless steel\u2019s smooth, non-porous interior minimizes microbial risk during filling.<\/p>\n\n\n\n
Guidelines:<\/strong><\/p>\n\n\n\n\n- Red wine (on skins): Fill to 70\u201385 % of capacity to allow cap expansion during fermentation.<\/li>\n\n\n\n
- White wine: Fill to 95 % since there is no cap formation.<\/li>\n\n\n\n
- Confirm that sampling valves, manways, and drains are securely closed.<\/li>\n\n\n\n
- Optional: use inert gas purging to eliminate oxygen from headspace before fermentation begins.<\/li>\n<\/ul>\n\n\n\n
Step 3: Inoculate and Start Fermentation<\/strong><\/h3>\n\n\n\nOnce the must is in place, yeast inoculation begins. Yeast selection and temperature management directly shape the aroma, mouthfeel, and fermentation speed.<\/p>\n\n\n\n
Process Recommendations:<\/strong><\/p>\n\n\n\n\n- Add activated yeast (approx. 20 g\/hL) and nutrient supplements if needed.<\/li>\n\n\n\n
- Set the fermentation temperature:\n
\n- White wines:<\/em> 14\u201318 \u00b0C for slow, clean fermentation.<\/li>\n\n\n\n
- Red wines:<\/em> 24\u201328 \u00b0C to enhance color and tannin extraction.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
- Monitor \u00b0Brix (sugar content), temperature, and CO\u2082 release daily.<\/li>\n<\/ul>\n\n\n\n
Step 4: Control the Fermentation<\/strong><\/h3>\n\n\n\nActive fermentation produces heat and CO\u2082. Controlling these factors ensures yeast health and preserves delicate aromatics.<\/p>\n\n\n\n
Key Controls:<\/strong><\/p>\n\n\n\n\n- Use Meto\u2019s advanced cooling jackets to keep core temperature within \u00b10.5 \u00b0C of the setpoint.<\/li>\n\n\n\n
- For red wines, perform gentle pump-overs or punch-downs to mix skins and juice evenly.<\/li>\n\n\n\n
- Seal the manway and apply CO\u2082 or N\u2082 blanket to minimize oxidation.<\/li>\n\n\n\n
- Optional: integrate digital sensors to track dissolved oxygen, pressure, and thermal profiles.<\/li>\n<\/ul>\n\n\n\n
Step 5: Clarify, Stabilize, and Mature<\/strong><\/h3>\n\n\n\nWhen sugar reaches near zero and fermentation slows, clarity and stability become the focus.<\/p>\n\n\n\n
Finishing Steps:<\/strong><\/p>\n\n\n\n\n- Cool the wine to \u2013<\/strong>2 \u00b0C for one week to complete cold stabilization and tartrate precipitation.<\/li>\n\n\n\n
- Maintain an inert gas layer to prevent oxygen contact during storage.<\/li>\n\n\n\n
- Filter or rack off lees as needed.<\/li>\n\n\n\n
- For extended stainless-steel aging, Meto tanks can support up to 12 months of maturation, maintaining freshness while avoiding oxidative effects from oak.<\/li>\n<\/ul>\n\n\n\n
