tanniiniseen

Tanniininen is a Finnish adjective describing something that contains tannins or has tannin-like properties. The term is commonly used in chemistry, food science, wine and tea contexts, as well as in discussions of plant-derived materials. When something is described as tanniininen, it often denotes an astringent or puckering quality associated with tannins.

In practice, tanniininen can refer to foods, beverages, or substances rich in tannins, such as certain wines, teas, or unripe fruits, where tannins contribute astringency and structure. It is also used in botany and chemistry to characterize compounds or plant extracts that belong to or behave like tannins. The word can appear in phrases such as tanniininen maku (tannin-like or astringent flavor), tanniiniseen nesteeseen (into a tannin-containing liquid), or tanniiniseen yhdisteeseen (into a tannin-containing compound).

Etymology and grammar: tanniininen is formed from the noun tanniini (tannin) with the adjectival suffix -inen. The illative singular form of the adjective is tanniiniseen, which is used to indicate direction or target in expressions of movement or influence, for example in sekoituksiin, nesteisiin, or vaikutuksiin that pertain to tannins.

Related terms include tanniinit (tannins) and tanniinittomä, or phrases describing low-tannin variants. In Finnish usage, tanniininen is contrasted with terms describing low or no tannin content and with descriptions of specific tannin sources, such as oak tannins or tea tannins.
