Failure of the inoculate to initialize – no activity takes place in the mash or it stops. This is likely to occur if the temperature is too high or some unwelcome micro-organism manage to infiltrate your sterilization process. Unfortunately, you will have to try again. With failure of initialization, mold is usually present floating on the surface of the lifeless mash.
After adding sugar, the makgeolli has a strange gluey taste – this is caused by excess yeast or nu-ruk which then reacts with the sugar to cause a temporary ‘gluey’ taste. However, this will subside so don’t throw it away just yet! Check here!
The mash manages to escape the jar and begin floating across the floor – silly-Billy, you used either too much nu-ruk or too much yeast. Mop-up – the overspill is better than an invasion of mold.
The makgeolli has separated in the bottle– this is quite normal. Shake the bottle before serving.
