Black Spanish Wine

BLACK SPANISH WINE

Black Spanish — also known as Jacquez — is a grape with deep roots in Texas winemaking history, and a personality to match. Think dark fruit, firm tannins, and an earthy backbone that can go dry and bold or slide into rich port territory depending on how you handle it. Most Texas wineries have leaned port-style, but treated carefully, this grape can hold its own as a straight table wine with real structure and complexity. This recipe makes one gallon and scales up cleanly.

The beginner trap: Skipping the twice-daily cap punch during primary fermentation leaves color, flavor, and tannin locked in the skins instead of in your wine.

Ingredients

• 12–15 lbs Black Spanish grapes (fresh or frozen), crushed and destemmed
• 1 crushed Campden tablet (or ¼ tsp potassium metabisulfite powder)
• 1 tsp pectic enzyme
• ¾ tsp yeast nutrient
• ¾ tbsp Oak-Mor powder (or ½ tsp medium-toast oak powder)
• 1 packet Bordeaux wine yeast (or any full-bodied red wine yeast)

Method

1. Sort through your grapes and discard any spoiled or shriveled ones. Crush and destem the fruit into your primary fermenter.
2. Stir in the crushed Campden tablet and pectic enzyme. Cover loosely and let the must rest overnight.
3. Check and adjust acid if needed, then stir in the yeast nutrient and Oak-Mor powder.
4. Prepare an activated yeast starter according to the packet directions, then pitch it into the must. Cover the primary fermenter.
5. Once fermentation kicks into high gear, punch the grape cap down twice a day to keep the skins submerged and extracting color and flavor.
6. When the specific gravity drops to 1.000, strain the solids into a press and extract the remaining juice. Transfer everything to a sanitized secondary fermenter and attach an airlock.
7. After one month, rack the wine into a clean, sanitized carboy. Top it up to minimize headspace and refit the airlock.
8. Repeat that racking process two more times, one month apart each time. Add one crushed Campden tablet after every other racking to protect against oxidation.
9. Once the wine clears on its own, decide whether you want it dry or slightly sweet. To sweeten, stabilize first, then add sugar syrup to taste, wait 14–21 days, and bottle.
10. Cellar the bottles for at least six months before opening.

Why this works

Black Spanish grapes are loaded with anthocyanins — the pigment compounds responsible for deep red and purple color — along with substantial tannins. Punching the cap keeps those compounds dissolving into the liquid instead of sitting trapped in a dry crust on top. The pectic enzyme breaks down pectin in the grape skins, which improves juice yield and helps the finished wine clear without going hazy. Oak-Mor adds a controlled dose of tannin and subtle wood character early in the process, mimicking what barrel aging would do over months. Bordeaux yeast specifically tolerates the high sugar and tannin load of thick-skinned red grapes without stalling out.

Notes

Frozen Black Spanish grapes work well here — freezing ruptures the skin cells, which actually improves color and juice extraction. If you can’t find Oak-Mor at your local homebrew shop, a small amount of food-grade medium-toast oak powder or oak chips works as a direct substitute. If your finished wine tastes too tannic or astringent, a longer cellaring time (up to 12 months) will smooth it out considerably.
