Make Kosher Wine at Home
Step-by-step guide from grape selection to bottling — including kosher certification
Home wine can be kosher if all handling from the start of crushing is done exclusively by Shabbat-observant Jews. For Mevushal wine, heat to 85°C before bottling. Consult with a qualified rabbi for guidance.
Step 1: Grape Selection
The foundation of great wine. Choose certified kosher grape varieties from a licensed supplier. In Israel, look for grapes from Judean Hills, Galilee, or Golan Heights.
For home wine to be halachically kosher, you must ensure the grapes were handled only by Shabbat-observant Jews from this point forward.
- Choose grapes with a sugar level (Brix) of 22–26 for dry wine
- Inspect for mold, rot, or damage before purchase
- Red varieties: Cabernet Sauvignon, Merlot, Shiraz
- White varieties: Chardonnay, Sauvignon Blanc, Muscat
- Buy 10–15 kg per 8–10 liter batch of wine
Step 2: Equipment & Sanitation
Clean equipment is the single most important factor in making good wine. Any contamination can ruin an entire batch.
- Primary fermenter: food-grade plastic bucket (20L)
- Secondary fermenter: glass carboy (10–20L)
- Airlock, rubber stopper, siphon tube
- Hydrometer (to measure sugar/alcohol)
- Sanitize everything with potassium metabisulfite solution (no rinse needed)
- Optional: crusher/destemmer, wine press
Step 3: Crush & Press
Breaking the grape skins releases juice and begins the winemaking process. Traditional foot-crushing is still effective (and fun)!
- Remove stems before crushing (destemming)
- Crush grapes into the primary fermenter
- For red wine: leave skins in during fermentation (adds color + tannins)
- For white wine: press immediately and ferment only the juice
- Add 50 ppm potassium metabisulfite to prevent oxidation
- Measure initial Brix with hydrometer
Step 4: Primary Fermentation
Yeast converts sugar to alcohol and CO₂. This is the most exciting phase — you'll see it bubbling and smell the transformation.
- Add wine yeast (Lalvin EC-1118 or Red Star Premier Classique)
- Maintain temperature: 18–24°C for red, 12–18°C for white
- Punch down the cap (skins) twice daily for red wine
- Fermentation takes 7–14 days for dry wine
- Monitor with hydrometer until SG reaches 0.990–0.998
- Rack (siphon) to secondary fermenter when sugar is nearly gone
Step 5: Secondary Fermentation & Aging
Secondary fermentation (malolactic) softens the wine. Aging in carboy or oak barrel develops complexity.
- Add MLF culture for malolactic fermentation (especially for reds)
- Keep airlock topped with water — no oxygen allowed
- Rack every 4–6 weeks to remove sediment (lees)
- Add SO₂ after each racking
- Minimum aging: 3 months for fresh whites, 6+ months for reds
- Oak chips or spirals can add vanilla and toast notes
Step 6: Bottling & Labeling
The final step — transferring your wine into bottles. Take pride in labeling your creation!
- Sanitize bottles, corks, and all equipment
- Fine the wine if needed (bentonite for whites, egg whites for reds)
- Filter using a wine filter (optional, for clarity)
- Bottle using a gravity filler or bottle wand
- Cork immediately with a hand corker
- Label with wine name, vintage year, and hashgacha
- Rest bottles upright for 1 week, then store on side
🧰 Complete Equipment List
Total basic equipment cost: ~₪400–₪800. Grape cost: ~₪10–₪20/kg. Every 10kg of grapes yields ~7L of wine (≈9 bottles).
