This is a very rare old Irish whisky (note the spelling without the ‘e’ in this case). Dunvilles made their whisky at the Royal Irish Distillery in Belfast which closed down shortly after World War II. When this was produced the term ‘Liqueur’ usually meant a whisky that was older and smoother than others. The fill level and label are good. The label has peeled off slightly but is still attached to the bottle. There is no content statement on the label. We estimate this example to be from the early 1900s or possibly even before.
