## Abstract

This invention describes the use of S-abscisic acid (S-ABA) and ethylene producing-agents such as ethephon to synergistically improve red color in grapes and to alter the sensory characteristics of wine.

## Claims

### Claim 1

A method of increasing cumulative harvestable clusters in red grapes comprising applying a synergistic amount of S-abscisic acid or its salts and ethephon to red grapes after veraison, wherein the amount of S-abscisic acid is from 88 to 292 mg/vine, the amount of ethephon is from 88 to 292 mg/vine, and the application volume is 5 to 400 gallons/acre.

### Claim 2 (depends on 1)

The method of claim 1 wherein the amount of S-abscisic acid or its salts is 88 mg/vine.

### Claim 3 (depends on 1)

The method of claim 1 wherein the amount of S-abscisic acid or its salts is 292 mg/vine.

### Claim 4 (depends on 1)

The method of claim 1 wherein the amount of ethephon is 88 mg/vine.

### Claim 5 (depends on 1)

The method of claim 1 wherein the amount of ethephon is 292 mg/vine.

### Claim 6 (depends on 1)

The method of claim 1 wherein the S-abscisic acid salt is selected from the group consisting of sodium, potassium, calcium, ammonium, magnesium, and amine salts.

### Claim 7 (depends on 1)

The method of claim 1 wherein the S-abscisic acid or its salts is applied by foliar spray, irrigation, or fertigation.

### Claim 8 (depends on 7)

The method of claim 7 wherein the S-abscisic acid or its salts is applied by foliar spray.

### Claim 9 (depends on 7)

The method of claim 7 wherein the S-abscisic acid or its salts is applied by irrigation.

### Claim 10 (depends on 7)

The method of claim 7 wherein the S-abscisic acid or its salts is applied by fertigation.
