WSET SAKE L3 Rice Cultivation
Q Describe the ideal features of soils for growing sake rice.
-Contain gluey substances, deposited by both plants and small animals to keep water.
-Contain high percentage of clay particles.
-Rich in nutrients.
-Rich in nitrogen.
-Free from volcanic ash.
Q Explain why rice seedlings need to be planted evenly in a paddy?
-Overcrowded field makes rice grain small.
-Widely spaced planting may cause inconsistent growth.
Q Farmers may drain and re-flood the paddy during the growing season. Explain these techniques and those purposes.
-The flooded paddy is drained once, and flooded again after 2-3weeks.
-The paddy remains flood until 10days before harvest.
-Vegetations submerged without oxygen produces poisonous acids and gases if they remain.
-The acids and gases disrupt healthy growth of the rice plants.
-Draining the paddy gives the rotten vegetations an access to oxygen. This helps the rotten vegetations to decompose and become nutrients for the rice plants.
-The dry period slows the vertical growth of the rice plants and the plants can give their energy to the production of large grains.
-The dry period enables the plants to strengthen their root systems.
Q What farmers can do to the soil during this drain and re-flooding period?
-Adding silicate, nitrogen and potassium fertilizers to help the growth of Shinpaku.
Q Explain why large temperature differences between day and night during ripening stage is important?
-To create Shinpaku within the grain of rice.
-Rice may become glutinous and hard to handle if the temperature remains high during night time.
Q Farmers harvest rice when the most of rice ears have ripened from green to gold. Describe the possible risk of harvesting at inadequate periods.
-Green, unripe grains may give unfavorable flavors to the sake.
-If harvested too late, the grains may become too dry and leads to the risk of cracking.
