had a packet of Prestige 8kg turbo yeast sitting in my cupboard for over 6months.and decided to use it. made up a wash 2 weeks ago,and distilled this morning, smell from wash wasn't great,started to distill surprise first 150ml deep blue, same colour as Windex window cleaner. next 500ml a fraction lighter in colour,but smells like ammonia knock your head of.the smell has gone right through the house.i stopped distilling and opened the boiler to find wash had gone thick like a thin soup and stink.
i was using my reflux still. first time using hbs yeast in 6 months.
has any one had same problem or any ideas.
the wash was clear
the spirits were 95avb at the parrot
