Rojas Vineyards in Oakville, California, produces three varieties of non-alcoholic wine: merlot, viognier, and pinot noir. The wine-master, Russel Hansen, has identified the following activities as cost pools for accumulating overhead and assigning it to products.
1. Culling and replanting. Dead or overcrowded vines are culled, and new vines are planted or relocated. (Separate vineyards by variety.)
2. Tying. The posts and wires are reset, and vines are tied to the wires for the dormant season.
3. Trimming. At the end of the harvest, the vines are cut and trimmed back in preparation for the next season.
4. Spraying. The vines are sprayed with organic pesticides for protection against insects and fungi.
5. Harvesting. The grapes are hand-picked, placed in carts, and transported to the crushers. 6. Stemming and crushing. Cartfuls of bunches of grapes of each variety are separately loaded into machines that remove stems and gently crush the grapes.
7. Pressing and filtering. The crushed grapes are transferred to presses that mechanically remove the juices and filter out bulk and impurities.
8. Fermentation. The grape juice, by variety, is fermented in either stainless-steel tanks or oak barrels.
9. Aging. The wines are aged in either stainless-steel tanks or oak barrels for one to three years depending on variety. 10. Bottling and corking. Bottles are machine-filled and corked. 11. Labeling and boxing. Each bottle is labeled, as is each nine-bottle case, with the name of the vintner, vintage, and variety.
12. Storing. Packaged and boxed bottles are stored awaiting shipment.
13. Shipping. The wine is shipped to distributors and private retailers.
14. Heating and air-conditioning of plant and offices.
15. Maintenance of buildings and equipment. Printing, repairs, replacements, and general maintenance are performed in the off-season.
