A theory for calculating proportions of each age and average age of products processed in fractional-blending systems has been developed and applied to several systems for aging wine. The average ages have been calculated in the oldest container of systems of from 4 to 8 barrels after 1 to 50 years of operation for withdrawals of 50, 25, and 10 per cent. The results show that fractional-blending systems produce beverages of a constant average age after varying periods of operation. The average age in the product may be increased by increasing the number of barrels in the system, by decreasing the per cent drawn off each time, or by making withdrawals less frequently.
