FAQ - Phenolic Maturity

Harvest Juice Panel
The Harvest Juice Panel presents a full range of winemaking tools for grape and must analysis. This is the most widely used analysis performed by ETS.

Scorpions Volatile Acidity Juice Panel
Early Detection to Minimize VA Production

Enhanced Juice Panel
The new Enhanced Juice Panel provides winemakers with an unprecedented array of information to help ensure a successful harvest.

Grape Moisture Content
A valuable analytical tool for measuring critical water concentration prior to harvest.

Catechin/Tannin "Ripeness" Index
Monitoring Grape Phenolics

Smoke Taint
Detect markers for "smoke taint" in wines or grapes.

Monitoring Bell Pepper Flavor
Monitor green bell pepper characteristics in grapes and juice by measuring IBMP concentration

Rapid Phenolic Panels
Quickly measure and respond to tannin and color indicators during harvest, fermentation and maceration.

Genetic Detection for Juice
This genetic-based analysis offers winemakers a tool for early detection of potential spoilage organisms originating in the vineyard or winery environment.

Monitoring Laccase
Detect laccase activity in grapes and wine without limitations caused by the moderate presence of sulfur dioxide.

Yeast Viability Analysis
This valuable analysis gives winemakers up-to-the-minute information on the activity of a particular fermentation.

Supplemental Analyses
Supplemental analyses related to harvest - includes fluoride and agricultural residues.

Sampling Programs
Develop a systematic strategy to collect random grape samples that are representative of the entire crop.

Potential Alcohol
Guidelines to estimate potential alcohol in fully fermented wine based on the analysis of fermentable sugar (glucose + fructose).
