how to make wine with concord grapes

Concord grapes, with their deep purple color and distinctive musky aroma, are a favorite for homemade wine. This guide will walk you through the process, from harvesting to bottling, ensuring you produce a delicious and memorable Concord grape wine.

Getting Started: Gathering Your Supplies and Grapes

Before you begin, gather the necessary equipment. A thorough preparation ensures a smooth winemaking process.

Essential Equipment:

  • Primary fermenter: A food-grade bucket with a lid is ideal (5-gallon capacity).
  • Airlock: Prevents unwanted bacteria and oxidation.
  • Siphon tubing: For transferring wine between containers.
  • Bottles and corks: For storing your finished wine.
  • Bottling bucket: For easier bottling.
  • Hydrometer: Measures the sugar content (essential for determining alcohol content).
  • Wine thief: A long, thin tube for sampling wine without disturbing sediment.
  • Sanitizer: Star San or a similar no-rinse sanitizer is recommended.
  • Crusher/destemmer (optional): Makes crushing grapes easier, but you can also crush by hand.
  • Press (optional): For extracting juice from the grape skins. If you don't have a press, you can gently squeeze the pulp.

Harvesting Concord Grapes:

  • Timing is crucial: Harvest grapes when they are fully ripe, typically late summer to early fall. Ripe Concord grapes will be plump, soft, and deeply colored.
  • Gentle handling: Avoid crushing grapes during harvesting. Bruised grapes can introduce unwanted bacteria.
  • Quantity: Plan on approximately 4-5 pounds of grapes per bottle of wine.

The Winemaking Process: Step-by-Step

Now, let's delve into the actual winemaking process. Each step is crucial to creating high-quality Concord grape wine.

Step 1: Crushing and Destemming

  • Crush: Gently crush the grapes, either by hand, using a crusher, or a combination of both methods. You want to break the skins but not pulverize the grapes.
  • Destemming (optional): Remove stems if desired. They can add bitterness to the wine.

Step 2: Primary Fermentation

  • Add yeast: Add wine yeast to initiate fermentation. Follow the yeast manufacturer's instructions for the exact amount.
  • Monitor fermentation: Keep a close eye on fermentation, checking the airlock regularly. The bubbling will slow down as fermentation progresses.
  • Temperature control: Maintain a consistent fermentation temperature (ideally around 70-75°F). Fluctuations can negatively impact the wine's flavor.

Step 3: Pressing and Racking

  • Pressing: Once primary fermentation is complete (typically 7-10 days), gently press the must (the mixture of juice, skins, and pulp) to extract remaining juice.
  • Racking: Carefully siphon the wine off the sediment (lees) into a secondary fermenter. This removes unwanted solids.

Step 4: Secondary Fermentation and Aging

  • Secondary fermentation (optional): For a drier wine, allow for malolactic fermentation (MLF), which converts harsh malic acid to softer lactic acid. This step is usually completed with a specific MLF culture.
  • Aging: Let the wine age for several months, or even longer, depending on your preference. This allows the flavors to meld and mature.

Step 5: Bottling

  • Prepare bottles: Thoroughly sanitize the bottles and corks.
  • Bottle the wine: Use a bottling bucket for easier and less messy bottling.
  • Cork the bottles: Ensure a tight seal to prevent oxidation.
  • Aging (continued): Allow the wine to age further in the bottle.

Troubleshooting Common Issues

Here are some common problems encountered during the Concord grape winemaking process:

  • Stuck fermentation: If fermentation stops prematurely, it might be due to low temperature, lack of nutrients, or too much sulfite.
  • Off-flavors: Off-flavors can result from poor sanitation, spoilage bacteria, or improper temperature control.
  • Cloudiness: Cloudiness might be due to insufficient racking or the presence of proteins.

Remember to research solutions to address any problems you might encounter.

Enjoying Your Homemade Concord Grape Wine

Your homemade Concord grape wine is now ready to be enjoyed! The exact taste and character will depend on the grapes, the yeast strain, and the aging process.

Remember to always store your wine properly to maintain its quality. Keep it in a cool, dark, and consistent temperature environment. Enjoy!
