Community Milling

Dry Creek Olive Company’s Community Milling days are an ideal way for the small olive grower to produce homegrown olive oil and celebrate the joys of harvest time. Come on out and enjoy the “fruit” of your labor! We have found that some of our most flavorful oils are produced on Community Milling days. The “field blending” created by combining neighbors’ olives produces amazing extra virgin oil!

As the grapes near harvest, our thoughts turn to Olive Milling season. Whether the harvest season will start early, be late or just as expected remains to be seen. Warmer weather in late August, September and early October may speed up the ripening of the olive harvest. We will watch mother nature in the weeks approaching the olive harvest season to ensure the schedule is locked in. Therefore, these dates may be subject to change as the season progresses. Please check back with us in late September for the final dates.

Our Community Milling dates for the 2018 Olive Harvest season are scheduled on the following days:

Sunday, October 28, 2018

Sunday, November 18, 2018

Sunday, December 2, 2018

Time (all dates): Olive deliveries received between 9 am and 2 pm. Olives will not be accepted after 2 pm. Oil Pickup: Oil can be picked up in the Trattore Farms Tasting Room after noon on the Friday following Community Milling.

Here is how it works: olives are delivered by customers early on Community Milling day and are combined and milled together into an extra virgin olive oil. The percentage of the total weight you contribute directly corresponds to the percentage of oil you receive once the olives are milled. Olives are collected only from 9:00 am to 2:00 pm. We will not accept olives after 2:00 pm.

We accept amounts from 5 lbs. to 700 lbs. at a rate of $0.90/lb. For quantities greater than 700lbs, please contact us for special pricing. There are no additional waste removal fees for community milling – the pomace is on us!

We recommend you pick no more than 24 hours before bringing your olives in for milling. Ideal storage containers include plastic 5-gallon buckets, clean trash cans, and macro-bins. Please do not store your olives in plastic garbage bags as they tend to rot more readily. To help ensure the quality of your olives, we recommend picking them within 24 hours of milling and storing them in a cool, well-ventilated place. When olives are delivered, they are inspected and are to be free of olive fly, rot, fungus or excessive bruising or damage. We reserve the right to refuse olives that have more than 10% olive fly damage, or if we deem them too defective to mill. You will need to take your olives with you if they are refused; we will not be able to dispose of defective fruit.

Over the past 10 years, the Olive Fly has made its way throughout California with a vengeance. It causes damage by laying its eggs in healthy olives. The larvae then hatch and eat the fruit, making the olives unsuitable for olive oil. One evidence of their presence is shown by “exit holes” in the fruit, or even active larvae or flies crawling on the fruit. If you have any evidence of the Olive Fruit Fly, you must pick all your olives and dispose of them properly by burying them or composting them. For more information on the Olive Fruit Fly please see the link below or consult your County Agricultural Adviser or research the internet for information.

Your oil will be ready for pickup at the Trattore Farms winery tasting room one week following your Community Milling day. Plastic, food-grade containers are supplied at a nominal price. We will only accept clean and dry, well-marked, food-grade plastic containers at the time of olive drop-off for oil collection. We want you to be completely satisfied with your olive oil and we cannot guarantee the level of cleanliness of non-food-grade containers brought in from the outside. When partitioning the oil, we round to the nearest ounce. We cannot guess or guarantee a certain percentage yield. Each person will receive the amount of oil in the percentage of weight they brought in. If your olives represent 10% of the total weight of the olives collected that day, you will receive 10% of the oil produced. When portioning the oil, we do it by weight and round to the nearest ounce.

Every season and batch will be different. Therefore, we cannot guarantee a certain percentage yield.

All Community Milling customers and Club member patrons of our tasting room are welcome to join us on these days (with or without olives) as we celebrate the harvest.

If you have further questions, please contact us if you plan to mill with us on one of these dates: (707) 431.7200 or email us at

We look forward to seeing you!
