Actually, I did find embedded tannins in data links about wines.
Below is one of several I found on the subjet.

Note to Michele:
Check out the French wording below and compare to the English above:the terms are used in the same context and setting (with full acidity and smooth tannins on the finish, etc.; and other qualifiers such as silky, fruity, long finish, etc., which are juxtaposed alongside the imbedded/embedded tannins.

Also, a embedded, a variant of imbedded is also used with tannins.

I think two of the options suggested (wrapped and coated tannins) are interchangeable with imbedded/embedded tannins but I was suggesting the solution that is most used.

French term (edited): tanins enrob�s

You be the judge, as you have the full context.

Lovely, rich Côtes du Rhône - more like a Villages wine with gamey characters and black cherry fruit, good structure and balance
Critic reviews "An exceptional Côtes du Rhône: its dark colour matched only by its nose of jammy blackcurrant and redcurrant with a touch of licorice. Full and unctuous, the palate has powerful but well-wrapped tannins. Already superb, it will age well" Coup de Couer/Exceptional (Guide Hachette 2002)

French term (edited): tanins enrob�s

Tanins enrobés, bien équilibrés et légèrement boisés. Longueur moyenne. Vin bien fait, qui jouera sur la séduction comme le 1999. »

Coated tannins. Well balanced and slightly oaky. Average length. A well-made wine which will have the same seductive charm as the 1999.”
