It is evident that the process could be further optimized by
monitoring the cooking and saccharification times, the
amount and fabricate of enzymes and yeast used, the duration
of the fermentation, the temperature level at which fermentation
is taking place, etc. The efficiency of the process could be
also improved by applying additional yeast on the second or
third day of the fermentation and extending the time allowed
for the fermentation process. The optimization of the process
was nevertheless out of scope of the present work.
