Oita Yeast (August 25, 2021)

大分酵母 大分酵母

We are currently in the middle of the production process for our barley shochu - Tsunezo. For this, we use Oita Prefecture’s original barley variety, Toyonohoshi barley. The yeast we use is also Oita Yeast, produced here in Oita Prefecture.

 

Oita Yeast was developed by the Oita Industrial Research Institute using the prefecture’s kabosu juice as a separation source.
In the brewing test, the Oita Yeast evaluation stated that the alcohol yield, flavour, and liquor quality were comparable to those of the Association Yeast and Kagoshima Yeast. In addition, it was said that it’s a great combination with our local Toyonohoshi barley.

 

Our barley shochu - Tsunezo and sweet potato shochu - Tsunezo, produced using Oita Yeast, won the Honour Award at the Kumamoto National Taxation Bureau’s Liquor Appraisal in the third year of Reiwa (2021).

 

The fact that our barley shochu - Tsunezo is produced using the Oita double-barrel (Toyonohoshi barley and Oita Yeast) means that it’s no surprise that it goes well with locally grown kabosu, especially when you think about the yeast’s source.

We have started our barley shochu production. We’re also looking forward to producing our delicious shochu this year.

Bakushu - It’s Time to Harvest the Barley (May 27, 2021)

Bakushu: When the barley spikes have fully grown, normally around early summer, we know that harvest time is here.
We visited a farm in Chitose, a village in Bungoono City, to see the fruits of this year’s harvest of Toyonohoshi, a new variety of barley being cultivated right here in Oita Prefecture, that is great for producing fantastic shochu.
We use Toyonohoshi in our barley shochu, Tsunezo and Tsunezo Breeze.

The Oita Prefecture Honkaku Shochu Kikizake - Sake Tasting Meeting (January 27, 2021)

焼酎利き酒会 焼酎利き酒会

The Oita Prefecture Honkaku Shochu Kikizake - Sake Tasting Meeting was held in 2020, hosted by the Oita Prefectural Sake Brewer Association. Ms. Iwata (appraiser, general manager) and Ms. Iehara (appraiser) from the Kumamoto Regional Taxation Bureau were both in attendance.
We at Kuge Honten exhibited our barley and sweet potato shochu. Both received high evaluations. We will now take on board the guidance we received and plan to exhibit at the Kumamoto Regional Taxation Bureau - Liquor Appraisal Meeting with the goal of winning a prize!

Barley Shochu Distillation - Vacuum Distillation (November 13, 2020)

 

After 12 days of fermentation the secondary mash, which has an alcohol content of 17% vol, is sent to the distiller for distillation (vacuum distillation).
Following the distillation, the barley shochu’s alcohol content has increased to 44% vol.
Vacuum distillation gives the shochu a milder clean taste. This clear light flavour is the result of the reduced-pressure distillation, achieved by using a vacuum pump.

Barley Shochu - Secondary (Main) Mash “Moromi” (November 12, 2020)

 

During the secondary or main mash, steamed barley and water are added to the primary mash. The steamed barley is added using an “air-shooter”, a kind of air-pump, that distributes the barley evenly into the mash.
The steamed barley starch is converted into glucose using enzymes in a process called saccharification. This is then quickly fermented using yeast which turns the glucose into alcohol.
We use a “parallel double fermentation” method to produce the alcohol. This means we perform the saccharification and fermentation in parallel - at the same time.

Barley Shochu - Primary Mash “Moromi” (November 11, 2020)

 

Today we moved the barley koji (prepared yesterday) from the shelf to the tank in preparation for the primary mash.
The primary mash consists of koji, water and yeast, and is fermented for 3 to 8 days.
The importance of this mash is paramount as it will directly affect the fermentation of the secondary mash.
We use barley koji for barley shochu whereas rice koji is mainly used in other kinds of alcohol.
