Sanitation is non-negotiable in winemaking. Proper cleaning prevents spoilage and off-flavors:
- Use a no-rinse sanitizing solution specifically designed for winemaking equipment.
- Sanitize all vessels, spoons, airlocks, and bottles before contact with must or wine.
- Regular boiling of small accessories like tubing and stoppers is advisable.
“Sanitation is the invisible foundation of successful winemaking.” We never skip or rush this critical step to maintain wine quality.
Preparing the Grapes
Proper preparation of Concord grapes is the foundation for producing high-quality Concord grape wine. Careful washing, sorting, crushing, and destemming ensure the essence and flavor of the grapes shine through in every bottle.
Washing and Sorting Grapes
We begin by thoroughly washing the Concord grapes to remove dirt, pesticides, and any unwanted residues. Use cold water and gently rinse the grapes in a large colander or basin. Avoid soaking the grapes for too long to maintain their freshness.
Next, we sort the grapes meticulously. Remove any stems, leaves, overripe, moldy, or damaged grapes. This step prevents unwanted bitterness and off-flavors in the wine. Remember, only the best ripe and plump grapes make for the richest, most flavorful wine.
| Step | Purpose | Tips |
|---|---|---|
| Rinse with cold water | Remove dirt and residues | Use gentle motion to avoid bruising |
| Inspect and remove | Eliminate unripe or spoiled grapes | Sort by hand for precision |
| Discard stems/leaves | Prevent bitterness and unwanted tannins | Use scissors or fingers carefully |
“The quality of your wine starts with the quality of your grapes.“
