Not Sure Which Wine Test You Need?

That's exactly why this directory was created.

The included Quick Test Selector helps connect common winemaking questions with the type of professional analysis you should investigate.

Questions such as:

Is my fermentation actually finished?

Did malolactic fermentation complete?

Does my wine have enough SO₂ protection?

Could Brettanomyces or another microorganism be affecting my wine?

Is my wine stable enough to bottle?

Which laboratory should I consider for regulatory or export analysis?

Start with the problem. Then identify the appropriate test and laboratory.

Perfect For

Home Winemakers — Know when you've reached the limits of home testing and where to look for professional analysis.

Serious Hobby Winemakers — Investigate fermentation, spoilage, stability, and bottling concerns with greater confidence.

Small & Boutique Wineries — Compare analytical resources and build stronger quality-control procedures.

Emerging Commercial Winemakers — Develop the testing and documentation practices needed as production becomes more professional.

Winery Owners & Production Teams — Keep a practical laboratory reference available when troubleshooting or preparing wine for bottling.

Stop Guessing. Start Testing.

A wine can look clear and taste finished while still having residual fermentable sugar, incomplete malolactic fermentation, insufficient protection, microbial activity, or stability problems.

Professional laboratory analysis can help answer questions that sight, smell, taste, and basic home testing cannot.
