❓ FAQ

Can I make this ahead of time?
Not really—soda water loses its fizz fast. Mix it right before serving!

Do I need fancy soda water?
Nope. Any plain club soda or sparkling water works great.

What if I don’t have a lemon wheel?
Just use a slice or a wedge. Even a lemon peel twist works!

Is it strong?
Not too strong—limoncello is sweet and lower in alcohol than most liquors, and the soda water keeps it light.

Can I make it sweeter?
You can! Add a splash of simple syrup or use a lemon soda instead of plain soda water.
