In just a couple of years, the Martini drinks will be 150 years old. Over time, the ratio between spirits and dry vermouth has changed - from equal parts to a 9-to-1 ratio today. During Prohibition, the ratio was usually about 2 to 1, making us a bit less dry. (The martini was initially made with gin, but ABSOLUT gives it a clearer taste.)
