the Brewing Society of Japan



1. Research and technological development on brewing

We investigate the characteristics of brewing microbes to maintain their own natures, the analytical methods of brewing products, and manufactural process controls.


2. To help our members through their brewing studies, technological evelopments, and promote their practical use.

1) Through the scientific conference "Nippon JMzM Gakkai", we provide our member
researchers and technicians a forum to present and announce their achievements and
discuss these.

2) We offer advice on technical problems of brewers and reply to the consultative
questions on brewing from anyone. Moreover, we accept the analysis or sensible
evaluation of brewing products and offer necessary materials or information for
them. (Charging a fee in some cases)

3) We hold the following seminar which serves in the education of brew masters and
coworker technicians. The general public is also invited to attend.
In these seminars, we confer an attendance certificate on students who attend the
sake brewing beginners’ seminar or the practical sake tasting training course.
Furthermore, we confer a title of "Master (Mistress) of Sake Tasting" on the student
who obtains results that are higher than a constant standard in the course, and also
confer a memorial plaque for particular excellence.

4) We offer many courses on brewing in Web-learning. Participants can study the
courses referring to the textbook using a PC anytime and anywhere.

5) We have a training system for the person who wants to learn a brewing technology
systematically by studying for a certain period of time.


3. To collect and stock the genetic resources of microorganisms and to
distribute them.

We collect microorganisms as genetic resources from Japan or in foreign countries
and elucidate their taxonomical and brewing properties and stock them. We also
distribute the strains which can be used in brewing.
The microorganisms which we distribute now are as follows.
These may be provided in a study purpose other than brewers to the domestic
research institute and university.

1) KyMkai Sake yeast
Foam forming strains: K-6, K-7, K-9, K-10, K-11, and K-14.
Non-foam forming strains: K-601, K-701, K-901, K-1001,
K-1401, K-1501, K-1601, K-1701, K-1801, K-1901, and KT-901.
Dry Sake yeast: K-701, and K-901.
Miscellaneous: High malic acid acid forming strain (No.28, No.77)
Urea non-forming strain (KArg-701, KArg-901), and Red colored strain.

2) KyMkai ShMchk yeast S-2, S-3, S-4 and Dry ShMchk yeast (S-2).

3) KyMkai Wine yeast W-1, W-3, and W-4.

4) KyMkai Persimmon yeast (For deodorization of persimmon tannin juice.)


Manufacturing process of the ampoule bottling yeast

[1] The yeast is cultured in a
200-300L vessel.

[2] Yeast cells are harvested and washed with sterilized water to remove the medium.

→ After strict quality checks, the cells go to a bottling process [3].

[3] Yeast cells are bottled to an ampoule and heat sealed.
[4] Labelling is the last process for the completed product.
Procedures [2] and [3] are performed in a sterile room.



4. Honoring brewing researchers and skilled technicians

We recognize achievements in brewing research, investigation, and technical
developments, and we also honor the skilled technicians for the purpose of further
improvement of their technics and succession of skills.
(1) ItM Yasuhei Prize, (2) Technical Prize, (3) Achievement Prize, and a prize of
encouragement for younger scientists of The Scientific Conference of Brewing Society
of Japan, (4) Prize for Skilled Technician of Brewing.

(1-3) are medals. (4) is a badge.
