I can't seem to find any information about these two traditional liquors. They belong to the category 과실주 (fruit liquors). In my text they appear in a long list of 과실주 as found in old cookbooks, with no other context. The list also provides no context: "...무화과주, 딸기주, 자이주, 선도주, 설리주, 연육주...." (Incidentally, I have found 선도주 to refer to the mythical peach of eternal life, and have translated it as "immortal peach liquor"--does that seem right?)
