Its levels can fluctuate due to numerous factors, including grape maturity and disease pressure. When gluconic acid levels become excessively high, it can have negative effects on wine quality and taste.   Reasoning:  Quality Assessment: Monitoring gluconic acid levels is essential for assessing grape quality. Elevated levels can indicate the presence of undesirable microorganisms or spoilage, potentially affecting the wine's overall acidity and flavor. Excessive glucon

The OenoFoss™ GO analyzer handles both grape must and wine samples with equal ease which makes it simple to track grape maturity according to weather conditions. “It is a very easy and intuitive instrument,” says Giuseppe Facchin. “All you need to do is go out into the field, pick up a sample, filter the juice with a normal filter and test.
