Harvesting and processing

Harvest
Autumn (October) for mature rhizome; fresh rhizome available all year round in crops

For fresh use (生姜 Shēng Jiāng) it is harvested before full maturity. For dried ginger (干姜 Gān Jiāng) it is harvested at full autumn maturity when the gingerol content is maximum.

Fresco (生姜 Shēng Jiāng)

Fresh rhizome washed, peeled or unpeeled depending on use. It is used directly or squeezed to extract the juice. It is a different form of the same plant with different properties.

Dried (干姜 Gān Jiāng)

Ripe rhizome washed, peeled and dried in the sun or with gentle heat until hard and fibrous. Dehydration converts gingerols into shogaols, more pungent and calorific compounds.

Charred (炮姜 Pào Jiāng)

Dried rhizome fried in a hot pan without oil until the outside is charred black and the inside is dark brown. It is extinguished by spraying with water. Intermediate form between dry and completely calcined.
