Gaiwan (General Description)

When the store describes brewing with a Gaiwan, it will be generalized as "making tea using the gaiwan as the brewing container". Since brewing techniques, styles, methods, are as flexible as they are, gaiwan brewing can be done in a variety of ways with different effects.

For store purposes, though, the only specification is that it uses a gaiwan, boiling water, and 5g of tea unless otherwise specified.
