I have maybe an odd question.
When running a steam fired spirit still, 2070 liters capacity a vapor escapes during the first 2-3 minutes at the beginning of the spirit run. It feels cold but it does not turn liquid and escapes with some pressure. The smell is not very nice..
The grainbill of the spirit is only based on optic barley, peated at 35-40 ppm, fermented using distillers yeast.
Any idea what it is???
Thanks
