METHOD SUMMARY

This category includes evaporative ethanol emissions for 1990 from the aging of wine in oak barrels to produce brandy.

ACTIVITY DATA SOURCE:  The amount of brandy stored in California during 1992 was obtained per communication with Wade Stevenson from the Wine Institute. The statewide brandy storage is apportioned to the counties using grape production and grape crushing data. The 1990 grape production in each county is from the Annual Crop and Livestock Report (Annual Crop report) prepared by each County Agricultural Commissioner. The amount of grapes produced in the 17 grape growing districts of California was determined by using the "Map and Definitions of California Grape Pricing Districts" from the California Department of Food and Agriculture (CDFA) with the Annual Crop report. The amount of grapes crushed in the grape growing districts is from the CDFA report, "Final Grape Crush Report 1990 Crop."

The following assumptions were made to apportion the statewide brandy storage to each county:

1) the amount of grapes produced is proportional to the amount of grapes crushed, and 2) the amount of grapes crushed is proportional to amount of brandy stored. First, the proportion of grapes produced to grapes crushed is used to determine the amount of grapes crushed in each county (produced in county/produced in district = X crushed in county/crushed in district). Second, the proportion of grapes crushed to brandy stored is used to determine the amount of brandy stored in each county (crushed in county/crushed in state = X brandy store in county/brandy stored in state).

EMISSION FACTOR SOURCE:  An emission factor for brandy was derived by Hugh Cook of the Wine Institute. This emission factor was derived by assuming that brandy is on average 120 proof (60% ethanol) and there is a loss of 2.5% per year per barrel.

TEMPORAL DATA:  The annual, weekly, and daily activities are uniform throughout the year, seven days a week and 24 hours a day.

DATE OF THE LAST UPDATE:  February 1992

GROWTH PARAMETER:  Dollar output for food manufacturing (SIC 20)
