I'm just brewing my second wash for the Airstill using the standard products provided plus what I would normally put in. This is Dextrose, filtered water, 'Still Spirits' turbo yeast and yeast nutrient, liquid carbon. All brewed at about 20 to 28 degrees.
The last batch I brewed with the same ingredients (except the water was not filtered) had a very yeasty smell throughout the fermentation cycle but came out well. This wash has a slight smell of banana (which I'm used to from brewing beer and try to avoid). The smell is slight - is this an issue?
