Alcoholic Fermentation (AF) Tracking, Bulk Entry & Temperature Control

🎯 Winemaking Goal

Monitor daily Alcoholic Fermentation (AF) kinetics on lot C03 - 26-SAUV-FA: log daily density, temperature, and cooling setpoint (Setpoint °C) from the lot sheet or via the cellar-wide Bulk AF Entry modal, record yeast nutrition (Fermaid E) and oxygenation (5 mg/L), and inspect the color-coded intervention markers directly on the interactive AF curve.

✅ Prerequisites

• Lot 26-SAUV-FA (140 hL, Sauvignon blanc) is active in tank C03 with status Fermenting.

🛠️ Step-by-Step Instructions

Step 1 — Log Daily Density, Temperature & Cooling Setpoint (Setpoint °C)

1. Open the lot sheet C03 - 26-SAUV-FA (Tracking tab).
2. In the New AF reading card on the right:
   • Enter Density (e.g., progressing over 6 days from 1082 → 1068 → 1050 → 1034 → 1022 → 1014 g/L).
   • Enter Temp. (15.5 °C to 17.2 °C, then 16.4 °C).
   • Enter Setpoint °C (16 °C).
   • Select any sensory aroma note (e.g., Slight reduction) and click Confirm.
3. The Alcoholic fermentation curve plots three series simultaneously:
   • Solid purple line: Density (g/L).
   • Dashed orange line: Must temperature (°C).
   • Horizontal dashed blue line: Cooling setpoint (16 °C).

Step 2 — Use the Cellar-Wide Bulk AF Reading Entry

1. During the morning tank round, open the Bulk AF readings modal from the Dashboard (/).
2. Enter Density, Temperature, and Cooling setpoint (or flag valve position) across all fermenting tanks in a single table—or use CSV Import / OCR Scan—and click Confirm all.

Step 3 — Record Nutrition & Oxygenation with Interactive Curve Markers

1. On C03 - 26-SAUV-FA, click the purple Job (Travail) button in the top right:
   • Nutrient addition at d = 1068: select Nutrition, choose stock item Fermaid E at 30 g/hL (4.2 kg automatically deducted from stock for 140 hL), and save.
   • Oxygenation at d = 1050: select Oxygenation, enter 5 mg/L in the built-in calculator (700,000 mg / 0.49 L O₂ gas for 140 hL), and click Save.
