CSA stands for Community Supported Agriculture.
CSA is an innovative model of running a farm whereby customers sign up as Annual Farm Members, and then the Farmer grows their food and delivers it throughout the season. There are no middle men, just a direct partnership between Farmer and Members. "Shares" of the farm's future harvest are purchased in advance by the Members and are often available in different sizes.
This arrangement works well because the Farmer knows exactly how much food to produce each month and has the money up front to help with cash flow. It also benefits the Members because they have a direct relationship with the people growing their food, which means they can visit the farm, talk to the farmer, and truly know where and how their food is being produced. Check out the Portland Area CSA Coalition website for more info on CSAs.
While most CSAs are vegetable farms, we have applied the model to pasture-raised livestock. When you purchase a Share from our farm, you are paying in advance for an assortment of frozen meat that will be delivered to your home on a monthly basis for a year. Your money will be used by us to raise the animals on our farm until they reach a desirable weight, at which point they are slaughtered in the most humane way possible and then butchered into cuts, packaged and frozen. We store the meat in our freezers and put together an assortment of cuts into 10 lb packages for delivery to our members on a monthly basis.
