How to Make Wine from Welch’s Grape Juice: A Step-by-Step Guide
You bought a case of Welch’s Concord grape juice on sale, and now it’s sitting in your pantry. You’ve heard people turn it into wine, but you’re not sure where to start. Maybe you tried once and ended up with something that smelled like nail polish remover.
This guide walks you through the entire process — from ingredients to bottling — so you get a drinkable, honest table wine on your first try. I’ve made this exact recipe over a dozen times, and I’ll tell you what actually matters and what you can skip.
By the time you finish reading, you’ll know exactly how to make wine from Welch’s grape juice without special equipment or a chemistry degree.
What You Need Before You Start
Making wine from store-bought grape juice is more forgiving than starting with fresh grapes. The juice already has the right sugar and acid balance. But you still need a few specific things.
Ingredients
- 1 gallon Welch’s 100% grape juice (no preservatives — check the label for potassium sorbate or sodium benzoate; those kill yeast)
- 1 teaspoon wine yeast (Lalvin EC-1118 works great for beginners — it’s tough and clean)
- 2 cups granulated sugar (optional — only if you want higher alcohol; skip for a lighter wine around 9% ABV)
- 1/2 teaspoon yeast nutrient (not strictly required, but it prevents sulfur smells)
- 1 Campden tablet (optional — helps kill wild microbes before pitching yeast)
Equipment
- 1-gallon glass carboy or food-grade plastic fermenter
- Air lock and rubber stopper
- Siphon hose (auto-siphon makes life easier)
- Sanitizer (Star San or similar — no bleach)
- Glass bottles with corks or screw caps (six 750ml bottles per gallon)
That’s it. If you want to skip buying a special fermenter, a cleaned plastic water jug works — but glass is easier to keep clean and see what’s happening.
Step-by-Step: Turning Welch’s Juice into Wine
These steps cover one gallon. Scale up if you want more, but don’t double the yeast — one packet handles 5 gallons easily.
- Sanitize everything. Mix your sanitizer according to the label. Drench the carboy, air lock, siphon, and any spoon you’ll touch. Rinse with hot water if the sanitizer says to. This step is not optional — dirty gear gives you vinegar, not wine.
- Prepare the juice base. Pour the Welch’s juice into the carboy. If you’re adding sugar, dissolve it in a cup of warm juice first, then pour it in. Don’t use boiling water — it sets off the pectin and creates haze.
- Add the yeast nutrient. Stir it in gently. No need to aerate much — Concord juice already has enough oxygen.
- Pitch the yeast. Sprinkle the yeast on top of the juice. Wait 10 minutes. Stir gently. Fit the air lock (fill it halfway with water or vodka). Put the stopper in the carboy.
- Ferment for 7–10 days. Keep the carboy somewhere dark between 65–75°F (18–24°C). Too cold and fermentation stalls. Too hot and you get off-flavors. You’ll see bubbles in the air lock — that’s CO2. When bubbles slow to one every 60 seconds, primary fermentation is done.
- Rack to a second vessel. Siphon the wine off the sediment (lees) into a clean, sanitized carboy. Leave the thick sludge behind. This step clears the wine and prevents yeasty flavors.
- Age for 3–4 weeks. Let it sit in the dark with the air lock on. If a new layer of sediment forms, rack again after two weeks. Most Welch’s juice wines clear up in about a month.
- Bottle. Siphon into clean bottles. Cork or screw-cap tight. Store upright for a few days, then on their side if you used corks.
Comparing Yeast Options for Welch’s Juice Wine
| Yeast Strain | Best For | Ferment Range | Alcohol Tolerance | Flavor Impact |
|---|---|---|---|---|
| Lalvin EC-1118 | Beginners, high sugar, low temp | 50–86°F | 18% | Neutral, clean finish |
| Red Star Premier Blanc | White wine style, crisp | 55–75°F | 15% | Mild fruity notes |
| Lalvin D-47 | Sweet whites, floral | 59–77°F | 14% | Enhances grape character |
| Lalvin K1-V1116 | Fast ferments, high acidity | 50–95°F | 15% | Slight citrus edge |
My go-to is EC-1118 for Welch’s juice because it’s a machine. It never stalls, and it leaves almost no yeast bite. If you want a slightly sweeter finish, try D-47 — but keep the temperature below 72°F or it throws off fusel alcohols.
Three Common Mistakes and How to Avoid Them
Mistake 1: Using juice with preservatives
Welch’s makes a “natural” line that’s just grapes. But their standard Concord juice sometimes contains potassium sorbate. That chemical stops yeast from reproducing. Check the label. If you already bought the wrong bottle, you can try adding more yeast (double or triple the dose), but results are unreliable.
Mistake 2: Skipping the sanitizer
I did this once. Used plain hot water. After three days I had a film on top. That was a bacterial infection. It smelled like wet dog. Throw out any batch that grows mold or smells like vomit. Sanitizing takes five minutes. Do it.
Mistake 3: Bottling too early
Primary fermentation looks done when bubbles stop, but there’s still CO2 dissolved in the wine. If you bottle right away, you’ll get fizzy wine and possibly exploding bottles. Wait until the air lock stays still for a full 48 hours. Rack it, then wait another week.
Frequently Asked Questions
Can I make wine from any Welch’s juice flavor?
Only 100% grape juice works reliably. Concord grape is the classic. White grape blends can work but often taste thin. Avoid blends with added sugar, high fructose corn syrup, or flavorings — they ferment unpredictably and leave a weird aftertaste.
How long does it take to make wine from Welch’s juice?
About 5 to 6 weeks from start to bottle. Active fermentation runs 7–10 days. Aging and clearing takes another 3–4 weeks. You can drink it young, but it tastes noticeably better after two months in the bottle.
Do I need a hydrometer?
Not strictly, but it helps. A $10 hydrometer tells you your starting and final gravity. That lets you calculate alcohol content (ABV) and know when fermentation is truly done. Without one, you’re guessing. If you drink grape juice for its flavor, you might not care about exact ABV — but for wine, it’s worth the small cost.
Why does my wine smell like sulfur?
That’s hydrogen sulfide, usually from stressed yeast. Cause is typically low nutrients or temperatures over 80°F. Prevention: add yeast nutrient at the start, and keep the fermenter cool. If it already smells, splash the wine into a clean jug (aerate it) — the smell will blow off in a few hours.
Can I backsweeten the finished wine?
Yes, but carefully. If you add sugar after fermentation, the remaining yeast will eat it and create more alcohol or carbonation. Use an unfermentable sweetener like erythritol, or add potassium sorbate (a stabilizer) 24 hours before adding sugar. A simpler route: serve the wine chilled — cold masks the dryness.
What You’ll Actually Get — and How to Improve It
Welch’s juice makes a simple, fruity red wine. It won’t taste like a Bordeaux. Think of it as a country table wine that goes well with burgers or pizza. The color is deep purple. The flavor is grape-forward with low tannins and moderate acidity.
If you want better body, add a cup of strong black tea during step 2 — the tannins add structure. For a more complex profile, toss in a cinnamon stick and a strip of orange zest during aging (remove after 5 days). Some home winemakers use a centrifugal juicer to blend in other fruits, but I keep it simple with just the Welch’s base.
Also consider: lemon juice maker machines aren’t relevant here, but if you ever try making wine from fresh juice, you’ll want one to acid-correct your must.
Five Quick Takeaways for Your First Batch
- Check the Welch’s label for potassium sorbate before buying.
- Sanitize everything — no shortcuts.
- Keep fermentation temperature between 65–75°F for clean flavors.
- Don’t bottle until the air lock has been still for two full days.
- Wait at least two months before judging the taste — young wine is rough.
- Add yeast nutrient even if the package says you don’t need it.
- Write down what you did so you can repeat or tweak next time.
That’s the whole process. Skip the fancy gear, follow these steps, and you’ll have a drinkable homemade wine for about fifteen bucks a gallon.
