The purpose of this study was to investigate the effect of alc. strength by volume (ASV) and storage conditions on turbidity in plum brandies. Different types of filter sheet were also tested for their effects on turbidity, as well as on the chem. composition and organoleptic characteristics of the distillates. The raw materials used were two plum distillates with initial ASVs of 76.77% volume/volume and 81.92% volume/volume The distillates were diluted to alc. contents of 37.5%, 40% and 50% volume/volume and stored under various conditions for 64 days. Filtration was performed using two depth filter sheets, with nominal retention rates of 0.40-0.48μm and 0.80μm, or with an activated carbon-based filter sheet. The lowest turbidity was observed in samples stored at ambient temperature with an ASV of 50% volume/volume Reducing the alc. content and storage temperature caused turbidity to increase. Samples prepared from distillate with an initial alc. content of 76.77% volume/volume were characterized by significantly higher turbidity than those produced from spirit with an initial ASV of 81.92% volume/volume Lowering the storage temperature resulted in a larger decrease in the concentration of volatile compounds after filtration. Use of an activated carbon filter sheet caused the greatest decrease in the majority of volatiles. Use of a filter sheet with a nominal retention rate of 0.80μm led to the greatest improvement in the organoleptics of the tested plum distillates.
