25
What will Sake producers look for while purchasing Sake rice?
Sake rice that can absorb the right amount of moisture, cooperate with and be penetrated by koji mold, and interact with various types of yeast.
26
What are the five grades of size for classifying Sake rice?
Santoh (Grade 3), Nittoh (Grade 2), Ittoh (Grade 1), Tokuto (Special Grade), Tokujo (Higher Special Grade)
27
For Tokutei meisho-shu, what are the guidelines when producing this sake?
Meaning "Special designation" the rice size, NO preservatives, coloring agents, flavors, or fragrances added during or after production, a regulation enforced by law.
28
Sake rice is milled with what machine?
Seimaiki, which is a vertical machine. The size of the machine is indicated by the size of the millstone, which ranges from 40 to 65 centimeters.
29
What are brewery workers called?
Kurabito
30
Briefly explain the milling process?
The milling process, (seimai) begins with brown rice (genmai). Inside the machine, the dry rice grains are slowly milled in a polishing chamber with a roll made from an extremely hard material, then fall vertically through the mill. The machine removes the outer layers, (fat and protein) which point the rice is considered white rice(hakumai). Once the polished rice grains leave the chamber, a series of perforated plates separate the resulting flour (nuka) and the adequately polished grains. A calibrated hole will reject rice that is insufficiently polished, moving it back to the top with a bucket conveyer to go through the process again.
31
What does the term seimaibuai refer to?
The amount of rice remaining after polishing It takes 50 hours to polish a grain of rice to %50
32
Describe the difference between lower seimaibuai and higher seimaibuai?
Lower seimaibuai (more fat and protein removed) leads to more elegance, delicate flavors, and vibrant aromatics. Higher seimaibuai (less fat and protein removed) produces more rustic and savory styles of sake.
33
In Japan, what is a brewmaster called, and where do they learn about Sake?
Brewmaster is Toji Toji shudan or Ryuha is the school or guild
34
After the milling process how long does the rice rest for?
About two weeks to rest and absorb ambient moisture.
35
Explain how Sake rice is washed and soaked?
-Wash and soaked to absorb water -Rice is packed in 10 KG or 22.5 LB in mesh bags, soaked for 30-second intervals, and weighed after each soaking to track how much moisture has been absorbed. -The temp of the water and rice must match to avoid cracking of the rice grain. -The volume of the water-soaked rice is brought to about 30% more than its initial weight.
36
Briefly describe the steaming process for Sake?
-The rice is steamed for 45 to 60 minutes to break up the starch molecules and sterilize the rice. - Adding an additional 12% moisture to each grain of rice -Goal, make rice hard on outside, soft on the inside, encouraging the koji mold to work toward the moist, starchy center once it is introduced.
37
What happens to Sake rice after the steaming process?
-Cooling period "karashi kikan", batches are separated, most will be used for the day’s yeast starter, "moto or shubo", and the rest (ranging from 20 to 40%) will be moved to the koji room, or "koji muro". -To create the best environment for bacteria growth, the rice for koji propagation needs to be more gently cooked than the normal rice used in sake production. -"Kakemai" (non-koji rice) is always at the bottom of the steaming tank. "Kojimai (rice that will be sprinkled with koji mold) is at the top for a gentler steam.
38
What type of Koji is most used for Sake production?
Yellow koji (Aspergillus Oryzae)
39
What is Koji Muro?
-A room usually resembling a sauna lined with wood or metal; the rice is spread out on a large table and koji mold spores are delicately sprinkled over top. -“Koji mold” is the name of the product sprinkled on the rice, and the resulting product is simply called “koji.”
40
What is amazake?
Sake that is produced using non- or low-alcohol producing yeast, making it sweet and fruity. It is centuries old and has health benefits.
41
How long does Koji rest inside the Koji muro?
-Koji rests for about 24 hours then moved to a more precise temperature-control system of wooden trays and boxes for further propagation and mixing to maximize even distribution of the koji mold. -After two days, it is moved out of the koji muro to stop the spread of the spore and prepare it for the yeast starter. -While there are machines that can do this process, most quality producers do most or all their koji production by hand.
42
What is a yeast starter for Sake production?
25 kilograms koji to 37 kilograms kakemai, are combined in a tank with yeast and 80 liters of water.
43
Why is lactic acid necessary in Sake production and how many methods have been used through the centuries?
Lactic acid protects the fermentation from unwanted bacteria. -Kimoto (Workers pound the mash with large wooden poles for hours at a time, one month for Moto) -Yamahai (no bâtonnage, one month for Moto) -Sokujo (adding lactic acid, two weeks for Moto) -Bodaimoto (mix steamed rice with raw rice and water to encourage the natural production of lactic bacteria)
44
After the addition or cultivation of lactic acid, what is the next process?
Koji, kakemai, and water will be added in three stages over the following six days in a process called "sandan shikomi".
45
Name the three stages of the sandan shikomi process?
hatsu-zoe, naka-zoe, and tome-zoe.
46
What are the quantities of water, koji, and rice by the final day of prepping the shikomi (fermenting mash)?
Roughly 1,310 liters of water, 200 kilograms of koji, and 800 kilograms of rice will be fermenting. The mash will run for 20 to 30 days
47
What is used for the most common form of pressing for regular Sake production?
Balloon-press air compressor (assakuki) where the solids (kasu) are passed and separated through a mesh and used for skincare products and a popular dish called Kasujiru
48
For Junmai Ginjo or Junmai Daiginjo Sake, what is used for pressing?
Fune, or box press. The box contains porous cloth filter bags (shibori fukuro) and is slowly hand-filled with sake from above before pressure is applied. This traditional method is more labor intensive, and the risk of oxidation is higher.
49
For the highest quality Junmai Ginjo Sake what is used for the most delicate way to press the Sake?
The shizuku (tear drop or gravity press) or fukuro-tsuri (hanging bag) method employs a bag (called sakabukuro) comprised of special materials and mesh not used for the normal pressing. The bag is hung inside a tank and only what drops out of the bag makes it into the bottle. One bag will usually hold 15 liters of fermented moromi, and the two-day process will yield roughly six liters of free-run sake. After the sake has dropped out of the bag, the rest may be pressed using a fune.
50
Sake can be categorized into what three types of pressing?
Arabashiri (“first run”) is barely cloudy, rough in texture, delicate. It is occasionally sold on its own. -Nakagumi (or nakadori, “taken from the middle”) is usually considered the best of the three stages, with the greatest balance and structure. -Seme (“final run”) may be included in a batch of sake but never separated or sold on its own.
51
What is muroka?
Non charcoal filtered sake that retains sake’s natural greenish-yellow tinge as well as the impurities that can make a sake taste raw. It also stops the initial flavors that come along with aging and slows color change. First created in the 1960s in the Chubu Area of Niigata.

Koshu is aged sake and made in one brewing year and bottled in the next Ogushu is extra aged sake and is produced from more than one brewing year
64
Why do breweries in the south and west part of Japan often produce rounder and richer sake vs the north where sake tends to be more delicate, lean, and even drier?
Climate and water. -Warm climate and softer water in the south and west -Cooler climate for a longer period of time and the water is harder in the north, and sake tends to be more delicate, lean, and even drier
65
For Sake production, where does the most famous water come from?

66
What minerals do brewers try to avoid for water selection and which minerals are preferred?
-Low in iron, to avoid oxidation and adverse reactions with amino acid, and low in manganese, to avoid discoloration. -Higher levels of potassium and magnesium are also preferable, as they contribute to the stabilization and flavor of sake.
67
