There are mainly two types of Bi Luo Chun that are sold on the market
nowadays, one is the "snail shell" that you bought, another one is the
"long thin twisted". In fact, the "long thin twisted" one is more
traditional, according to the local tea farmers from Jiangsu province,
the way they describe the Bi Luo Chun is "brass wires stripe, screwy,
full of fine hairs, floral fragrance and fruity taste, refreshing."
The color of the original harvesting area Bi Luo Chun is much whiter
than those are harvested outside Jiangsu province.

About the "snail shell" one is a sort of new technique green tea, it is
pretty close to the gunpowder but much less tight, and it used lower
grade of leaves. Compare these two Bi Luo Chun, the price of the "long
thin twisted" is way higher than the "snail shell". But of course, the
"snail shell" also has its own character and it is indeed a good daily
tea.
