Limoncello is mainly produced in
southern Italy, especially in the region around the
Gulf of Naples, the
Amalfi Coast,
Sicily and
Gargano. Traditionally, limoncello is made from the
zest of Femminello St. Teresa
lemons, also known as Sorrento or Sfusato lemons. Lemon zest, or peel without the pith, is steeped in
rectified spirit until the oil is released. The resulting yellow liquid is then mixed with
simple syrup. Varying the sugar-to-water ratio and the temperature affects the clarity,
viscosity, and flavor. It has a slightly turbid appearance, which originates from the presence of small (approximately 100 nanometers)
essential oil droplets suspended in the drink. Opaque limoncello is the result of spontaneous
emulsification (otherwise known as the
ouzo effect) of the sugar syrup and extracted lemon oils. Commercial production was about 15 million liters in 2003. ==Popularity==
