HI David, After being pressed out and over its life on the shelf, should a fresh milky oat tincture stay somewhat close to the nice greenish/white /light brown milky color it gets when first being made? If it ages to a darker color throughout like many other tinctures, does this mean there is something wrong with how it is being extracted? And do we want to be seeing a settled out layer of light colored sediment at the bottom of the jar? As best as I know, I am harvesting in prime milky stage. I have made it both 30% (calculating water weight by drying a sample) as you have taught us and as a "75% alcohol extract" without calculating water in the fresh plant. Regarding color, results are variable in how the tincture turns out color-wise with both methods. I'd appreciate any thoughts.

After being pressed out and over its life on the shelf, should a fresh milky oat tincture stay somewhat close to the nice greenish/white /light brown milky color it gets when first being made? No, as most tinctures age colors fade and they usually get darker. It in most cases does not affect quality or efficacy. If it ages to a darker color throughout like many other tinctures, does this mean there is something wrong with how it is being extracted? And do we want to be seeing a settled out layer of light colored sediment at the bottom of the jar? Yes, this too is common and not an issue.
