单宁酸

Off dry on the medium bodied palate.Quite herbal but overall lacking any class.Lean and stemmy.

味道强烈，后味中还交织着丝淡淡的草药香味，清新爽口。

The conversion film is probably constituted of amorphous and pored alloying tannate chelate.

这种转化膜很可能是有定孔隙的非晶态合金膜构成.

The biological stability(assessed by AOC), had close relation to tannin value, and was increasing with the tannin value, but it had no velation to the pore size distribution.

滤池出水的生物稳定性与值有密切关系，值越低，出水的生物稳定性越高，与孔径的分布则没有关系。
