Our Commitment to 100% Grassfed, Year Round!

One of the many positive distinctions that we enjoy with our 100% grass fed milk is the seasonality of it. What the cows are eating has a direct impact on the milk that they provide, and lucky for us, our cows eat no grain - ever, only pasture grasses and forage (including many wild and native grasses, legumes, and flowers - Meg & Arden spend a lot of time planning and planting the pastures' bounty!). In winter, the cows eat grass hay and alfalfa hay, as well as some standing grass leftover from the late-fall growth.

About Windsor Dairy

Windsor Dairy is owned and operated by Drs. Meg Cattell & Arden Nelson, board certified bovine veterinarians. Windsor Dairy employs weekly bacteria testing to insure that your milk is free of bacterial pathogens.

Milk Shares:

In May of 2005 the Colorado state legislature recognized that people should have the freedom to consume raw milk. It is now legal to drink fresh milk from a cow that you own.

This means you can buy a share of a cow in our herd and board it at our farm. In exchange you have access to the most delicious and nutritious milk we know of. Please review our FAQs to find information on how to get started.

You may visit your cow during our pick up hours, and we encourage you to do so. We perform a service for you by feeding, caring for, and milking your cow, and you benefit by being able to utilize the milk.
