On National Farmers Day we would like to thank and give our gratitude to all the hard working farm families across this great nation. Thank you for your daily work and sacrifice.

As our family celebrates 115 years of farming the Yakima Valley, we are thankful for all this land has given us.

For me, I am thankful to have grown up on a family farm and to have watched my father love a way of life so deeply. Today, I am honored to farm and tend to that same piece of land.

Another big week ahead at County Line and in Prosser. Catch the Crush weekend is taking place at all participating w**eries.

Did you know this year marks our families 115th harvest in the Yakima Valley? Our story and love for the area all started when my great grandfather, a poor immigrant farmer, settled in an area known as Rocky Flats. With the introduction of the ROZA irrigation project they moved to more prosperous ground on County Line road.

In honor of this milestone, the County Line Red, will be $115 per case during Catch the Crush weekend. We will also be pouring the Carl Reserve and some other fun w**es.

We will be open the following days this week:

Thursday Oct. 8th, 11am - 8pm.
Friday Oct. 9th, 11am - 8pm
Saturday Oct 10th - Closed for Private Event
Sunday Oct 11th, 11am - 5pm

Another beautiful wedding yesterday at County Line. Congratulations to the Russell’s.
