Wine Testing Labs

Using state-of-the art enzymatic discrete analyzation tools our lab can run just about any test needed for wine and hard cider production. We offer this at a discounted rate for those utilizing our bulk wine production capabilities, or as a standalone service for clients simply looking for a lab partner.

At Fenn Valley, we provide wine testing services that ensure your wine meets the highest standards of quality, consistency, and stability. Our wine testing laboratory is equipped with state-of-the-art enzymatic discrete analyzation tools, allowing us to perform a wide range of wine analysis for wineries and cider producers.

Whether you are utilizing our bulk wine production services or simply need a reliable wine lab testing partner, we offer affordable, precise, and timely analysis to help you maintain full control over your production process.

Our wine testing lab is designed to meet the needs of wineries at every stage of production. We provide comprehensive wine analysis to monitor fermentation, stability, and overall wine quality.

1. Fermentation Monitoring & Yeast Health Analysis

To ensure smooth and efficient fermentation, we offer detailed testing on:

• Brix (sugar levels) – Monitors the fermentation process and tracks sugar depletion.
• Yeast viability and nutrition – Determines if yeast requires nutrient supplementation for a healthy, efficient fermentation.
• Alcohol content (ABV) – Ensures compliance with labeling and legal requirements.
• Malolactic fermentation progress – Tracks bacterial conversion for smooth, balanced wines.

Our precise wine analysis for wineries helps winemakers avoid stalled fermentations, off-flavors, and costly production errors.

2. Chemical Composition & Stability Testing

For wine to be stable and ready for bottling, it must undergo a series of wine testing services that evaluate key chemical components:

• pH & Total Acidity (TA) – Ensures proper balance and mouthfeel.
• Volatile Acidity (VA) – Detects spoilage risks from acetic acid bacteria.
• Sulfur Dioxide (SO₂) Monitoring – Essential for oxidation and microbial stability control.
• Residual Sugar (RS) Analysis – Ensures wines meet target sweetness levels.
• Dissolved Oxygen (DO) & Carbon Dioxide (CO₂) Testing – Monitors oxidation potential and wine freshness.

By analyzing these factors in our wine testing laboratory, we help wineries maintain consistent quality and prevent spoilage or microbial issues.

3. Microbial & Contaminant Testing

Microbial contamination can ruin an entire batch of wine. Our wine testing lab offers:

• Brettanomyces Detection – Identifies spoilage yeast that can cause off-flavors.
• Lactic Acid Bacteria (LAB) Testing – Ensures proper malolactic fermentation without unwanted bacterial activity.
• Yeast Contamination Screening – Detects rogue yeasts that can affect wine stability.

With our wine lab testing, you can safeguard your wine from unexpected microbial faults.

4. Stability & Bottling Readiness Testing

Before bottling, wines must be checked for stability to ensure they remain clear, balanced, and free from defects over time. We conduct:

 

• Cold Stability Testing – Prevents tartrate crystal formation in bottled wines.
• Heat Stability Testing – Ensures proteins do not create haze or sediment.
• Filtration Suitability Analysis – Determines whether additional filtration is needed before packaging.

Our wine testing services ensure that wines are bottled in optimal condition for long-term stability.

Fenn Valley offers flexible wine testing solutions, whether you need occasional lab support or a long-term wine analysis partner.

With our wine testing laboratory, wineries can confidently produce high-quality wines with precision and consistency.
