AB  - Three series of determinations—refractometer, pH, and titratable acidity—were made on must for 154 sets of 2 or 3 boxes of grapes, and two series of readings—refractometer and pH—were made on juice from berries for 310 boxes of grapes harvested in a systematic way. If the series were regarded as being random the distributions were nonnormal, indicating vineyard heterogeneity. Plots against box number indicated decided oscillations in the data. The vineyard variations that are detected and described here are more subtle than can be handled by usual field trial designs.
