Sliwowica (slivovitz) has long been recognized as a top achievement of Polish alcohol-making craft. It is a strong (about 70% vol. or 140 proof) plum brandy. High-quality Polish sliwowica is pleasant to the taste and has a delicate fruity aroma, despite its strength. When you take a little sip and close your eyes, you can almost see sunny plum orchards where the drink has its beginnings.
