Fresh Spring Grass and the Flavor of Raw Milk

Have you ever opened a bottle of raw milk and noticed a slightly different flavor? I have. It’s not spoiled, but you know that it tastes a little different than usual. If you have a sensitive palate like me, you notice this a lot sooner than some people do.  

You check the sell-by date, still another 10 days off. That’s not it. You taste it again. Not spoiled, but what is it? 

The most likely cause, especially if you notice this in the Spring, is a sudden change in a cow’s diet can directly affect the flavor of the milk. After a winter of eating hay, the cows start to graze fresh grass again in the Spring. This wonderful fresh grass, that we all have been waiting for, may be giving the milk a stronger flavor!  

Like so many other things that we do in producing raw milk, we are also very intentional in transitioning the cows to fresh grass in the Spring to lessen any flavor change. Here are a few things that we do: 

Limited Grazing - only a couple of hours a day for the first few weeks to prevent having a sudden change in the cows diet. 

Patience - waiting till the grass is taller before we let the cows on it. 

Beware of Dandelions - cows absolutely love dandelions and will eat them first. If a pasture has a lot of dandelions, we will limit their grazing there to prevent the milk from tasting "grassy". 

Milk that tastes “grassy” is perfectly safe to consume, but our goal is to provide you with a sweet flavored raw milk that you can feel good giving to your family. 

If you come across some of our raw milk that tastes unusual or if you ever have any questions or concerns, please contact us. And remember, we will never sell you anything that we wouldn’t consume ourselves. 

Enjoy a cold glass of raw milk or raw chocolate milk!

What do grass-fed cows eat in the winter

 Q. Farmstead Acres cows are 100% grass-fed, right? But it's winter time, so how can they eat grass when the grass isn't growing?    A. In the summer, we make hay and feed it to the cows in the winter.   Hay is grass that we mow off and store in bales. If you visit the Farm, you will notice the oversized marshmallow loafs behind the Farm Store. Each of these hay bales weigh almost a ton. Cutting back the white wrap reveals dried summer grass that is slightly caramelized from the lacto-fermentation that occurs after the grass is wrapped in the bale. (This can be compared to harvesting vegetables in the summer and canning for the winter time.)     During the day we let the cows out on pasture to exercise and we unroll a hay bale for the cows to eat since there is no grass growing. This method is called bale grazing. Any hay that the cows do not eat gets trampled into the ground feeding the earth at the same time that we are feeding the cows. Along with their excrement, this is a wonderful fertilizer. When spring time comes you can tell exactly where the cows were bale grazing because the grass is thicker and greener!  During the night our cows prefer the warmth and comfort of our new loafing barn, bedded down on a nice clean layer of straw for the night.  Here in the loafing barn we also unroll hay in the feed aisle for any cow that wants a midnight snack.  If you were a cow, would you want to live at Farmstead Acres?  Thanks for joining our mission of being true stewards of the land and providing Real Food.
