What is Sake Made Of?

Whether you’re a sake connoisseur or a curious novice, the question that often arises is, “What is sake made of?” This article will answer that question comprehensively, delving into the rich and fascinating world of this traditional Japanese beverage.

The Essence of Sake: A Brief Overview

Sake is a fermented beverage native to Japan, often referred to as Japanese rice wine. However, the process of making sake is more similar to beer than wine, as it involves converting starch into sugars which are then fermented into alcohol. This process is known as multiple parallel fermentation, a method unique to sake.

The Core Ingredients

Fundamentally, sake is made from four basic ingredients: rice, water, koji, and yeast. Let’s look at these in more detail.


Rice isn’t just the primary ingredient of sake; it’s its soul. But not just any rice will do. Sake is typically made from specific varieties of rice known as “sake rice” or “sakamai”. These rice types are larger, contain less protein and lipids, and have a higher concentration of starch in the center of the grain.

Rice undergoes a process called rice polishing to remove the outer layers and expose the starchy core, crucial for brewing quality sake.


Water constitutes around 80% of sake, and its quality significantly influences the final product. Japan’s natural supply of soft water is one of the reasons why the country excels in sake production.


Koji is a type of mold, scientifically known as Aspergillus oryzae. This magical mold is responsible for converting the rice’s starch into fermentable sugars.


Yeast is the workhorse in the fermentation process, transforming the sugars into alcohol and carbon dioxide, while also imparting various aromatic compounds.

Types of Sake and Their Ingredients

Sake is not a monolith; there are several types of sake, each with distinct characteristics, flavors, and brewing methods. For instance, Junmai is pure rice sake, made solely from rice, water, koji, and yeast. On the other hand, Honjozo sake includes a small amount of distilled alcohol, which enhances flavor and aroma.

The Secret Ingredient: Mastery and Tradition

An often overlooked but crucial ingredient in sake production is the human factor – the mastery, tradition, and passion of the Toji (master brewer) and their team. This unwavering commitment to excellence is evident in every sip of sake.

So there you have it – the answer to the question, “What is sake made of?” From the quality of the rice and water to the type of koji and yeast used, each ingredient plays a crucial role in shaping the final product. But ultimately, it’s the skill and passion of the sake brewers that bring these ingredients to life, resulting in the diverse and enchanting world of sake. Kanpai!
