The 3 mistakes that ruin homemade wine (and how to fix them)
I've been making wine in Georgia for over a decade, and I've tasted thousands of homemade wines — from incredible to undrinkable.
Here are the three most common mistakes I see:
1. Wrong harvest timing
Most people pick grapes too early or too late. Too early = sharp, acidic wine with no body. Too late = overly sweet, flat, and prone to spoilage. The trick is measuring sugar content (Brix) and tasting daily in the final week before harvest.
2. Poor temperature control during fermentation
Fermentation generates heat. If your must gets above 30°C, you'll kill off the yeast and end up with a stuck fermentation — a half-sweet mess. If you don't have a temperature-controlled room, ferment in smaller batches.
3. Ignoring sanitation
This is the #1 killer. One dirty bucket, one unwashed qvevri, and you've introduced bacteria that will turn your wine to vinegar. Clean everything. Then clean it again.
Master these three fundamentals and you're already ahead of 90% of home winemakers.
I teach all of this (and much more) in my Complete Winemaking Course — from grape selection to bottling. If you're serious about making wine you're actually proud of, come learn with us.
