Soju is originally from Korea, where it was first distilled around the 14th century. Unlike vodka, soju has a natural hint of botanicals that can make for a smoother taste as opposed to vodka, which can sometimes come off as harsh at the end. It is also not only lower in calories than vodka, but it is also lower in proof. Beloved since 1924, Chamisul Original is the original classic soju, a neutral spirit distilled from rice.
