White miso is a generic term for miso that is whitish or pale-yellow in color. It’s mainly produced in Western Japan where the wether is relatively warmer than Easter Japan.
There are several types of white miso, and the taste differs depending on the type.

What Is White Miso Made from?
Just like the other miso, white miso is made from soybean, koji, and salt. By aging and fermenting the mixture of those 3 materials, miso is completed.
As long as miso is white (pale-yellow) in color, you can call it “white miso”. But it can be categorized in the basis of raw material, the type of koji.
・soybean + koji rice = (white) rice miso*
・soybean + barley koji = (white) barley miso
*Usually sweet white miso is made with koji rice.
By the way, there is also koji called “soybean koji”, however, miso made with soybean koji is always categorized as red miso.

Why Is It White?
Although raw materials of white miso and red miso are the same, why it turns out white?
There are 2 main reasons in this.
In order to make white miso, you need to mix koji rice or barley koji with cooked soybean and salt. So the point is that how does the soybean cooked?
Unlike red miso, soybean for white miso must be boiled.
For red miso, it needs to be steamed so that amino acid contained soybean can react with sugar and change miso color brown. (This is called Maillard reaction.)
By boiling soybean with plenty of water, amino acid (protein) contained in soybean will be melted in hot water and lost. That means this cooking process can suppress Maillard reaction.
In addition, using plenty of koji which means the amount of soybean is much less than typical red miso also suppress Maillard reaction.
The aging period of white miso is shorter than the one of red miso. It could be only a few days at least, and about 3 months at most.
There will be more enzyme produced by koji because white miso is usually using larger amount of koji than red miso. Those enzyme let white miso has shorter aging period.
What Does White Miso Taste Like?
The taste of white miso is more likely to be sweeter than red miso.
Sweet white miso produced in Western Japan is especially sweet, and its salinity is about half of red miso. You might not feel saltiness from those sweet white miso at all.
However, there are exceptions. Some of white miso is still salty, and that’s almost as salty as red miso.
Anyway all of them has great koku and excellent flavor from koji in addition to the saltiness and sweetness.
