Step 1

Peel the lemons and add their skins/zest to a glass container. Pour in the vodka and close to seal. Place it in a cool and dark place for at least two weeks, ideally a month. Every few days give it a shake.

Step 2

When the limoncello concentrate is ready, make the syrup. To a medium pot, set over medium heat, add in the sugar and water. Cook until the sugar has dissolved. Transfer to the fridge to chill, at least 10-15 minutes.

Step 3

Strain the limoncello, being sure to press down the lemon skins to release any of the limoncello. Discard the skins. Mix together the cooled simple syrup and the limoncello concentrate.

Step 4

Transfer them to glass bottles and place labels. I divided them amongst six (6-ounce) bottles.

Step 5

To make the spritz, add ice to a glass. Pour some limoncello in the glass along with some sparkling water and enjoy.
