Bitter aftertaste in goat milk?

Okay so i have 3 dairy goat 2 sadly lost their first time kids this spring gamora lost hers about a month ago and victoria lost hers about half a month ago, gretchen had 2 and both are getting ready to move to their new homes. since the other two lost their babies i have been milking them and freezing the most of it for soap, but i want it for drinking but it was havin a bitter aftertaste an i was chalking this up to the colostrum still being in the "baby" milk as some have said so i figured i milk them out for a few weeks then be able to keep the good milk. well here i am still having a bitter taste.
So the facts are all my does get the same food, timothy hay and orchard grass hay which they love, alfalfa pellets and some feed at night an on the milking stand. MY buck is in the connecting pen but since i put him in it he has been less "bucky" and really has never smelled. They have free choice of minerals and baking soda and all were given copper bolus as well.
The milk isnt goaty its got a bitter aftertaste and i decided to milk the does separate last night and taste test and gamora over a month since she kidded has the bitter taste, and victoria less then a month since kidding her milk taste fine?? I am lost they get the same everything so im worried its something with gamora now. Her udder seems fine she is a good milker as long as food is infront of her she doesnt mind me milking at all and is the first one to want on the stand so im not sure what could be the problem? im asking on multiple sites and looking up info myself as well

Does she have access to any bitter herbs for snacks?  Are there weeds close enough to the pen so that she can browse?

Here are some things i think could be tried.

-the goat milk could be fermented. I drink all of my goat milk in the form of whole buttermilk. It is real easy to make daily.
-The goat milk which has the bitter aftertaste, could go to feed some pigs or chickens, or cats, or even be used to cook with.


the goat with the bitter aftertaste, might be like this. I had a goat once where her milk was always bitter even 3 months of milking her daily. She was a first time mom. Maybe the milk will taste better the second time around.

I do not think the buck is attributing to this aftertaste.

Maybe this is just me but i love drinking the colostrum milk. I usually do not get a lot as it is going to the newborn kids.

She gets access to the same stuff that all the other goats get feed hay and mineral wise and its mostly just the grass in the pasture they graze on, but its just her i taste tested them seprate last night and its only the one shes a FF and kidded 3 weeks ago the other goat is also a FF 2 weeks ago and some people are saying maybe its just taking time for her milk to taste better

It could be that the bitter-tasting milk goat might have udder congestion or mild mastitis - you can feed dolomite to help this. Observe the temperatures of their udders and their milk - you might find that the one with bitter-tasting milk has a warmer udder or warmer milk. Dolomite can't hurt anyway, so it's worth trying even if you don't notice anything with the udder or milk temperature.

Sometimes it is just the case that different goats have different tasting milk.

Hi, one our goats had bitter tasting milk at first. Colostrum milk seems to be more yellow than white in color. Color might be an indication of what stage the milk is flowing.

Anyways, we read somewhere that kelp could make the milk bitter. We stopped feeding kelp. Getting the milk cold quickly helps too. We milk into frozen mason jars. Put the jar in a cooler. This way we milk the does, their milk gets cold quickly. Then we filter the milk into frozen mason jars. Place the milk in the freezer for an hour. Then into the fridge.

Doing these things has helped the milk tastes so much better. Hope this helps.
