The Tea

18 Ruby is Alfredo Lin's take on Taiwan's famous Ruby #18 black tea. He patented the name "18 Ruby" in Taiwan for his own batches, which are of superior quality. Like many other famous teas, Ruby #18 is often poorly processed material that depends on marketing and packaging. However, Alfredo's "18 Ruby" is truly fantastic, thanks to two reasons:

(1) Alfredo learned to craft Ruby #18 from Master Aones, the Taiwanese teamaster who first perfected and popularized the tea. Like many Taiwanese teamakers, Alfredo's background is in oolong tea. He quickly became an award-winning black tea specialist under the tutelage of Master Aones.

(2) Alfredo harvests the tea from his own all-natural tea garden. This tea garden was once depleted by chemical use, and the soils were very poor; as a result, the tea plants were not very healthy. Alfredo has revived the tea field by reintroducing native micro-organisms to the soil, and by using organic fertilizers. It has become his passion to convert conventional tea fields into healthy, biodiverse gardens.

In Alfredo's garden, the tea plants have a distinct pink-yellow hue in the young shoots. This reflects a particularly high thearubigin content in the leaves, thanks to the incredibly healthy soil and environment.

The Ruby #18 style is named after the No. 18 cultivar, Hong Yu "Red Jade", which was developed by Taiwan's Tea Research Extension Station (TRES) for black tea production. The cultivar is a cross between a large-leaf Assam cultivar, and the native Taiwan wild mountain tea tree. Cultivar No. 18 produces a distinct herbaceous, bright fruit and menthol profile, and exhibits high thearubigin content when cultivated correctly.
