We are growing Interdonato, Euroka, Lisbon, Meyer and few local varieties.
I like the taste of Euroka most. I enjoy Interdonato too but the tree and the fruit is too delicate to deal with
As Millet mentioned PVE sets very sparse fruit, I walk around the tree to find lemons but "the look", it worths the space it takes.
I sent PVE fruits to a gourmet writer, he loved the fruit, both the look and the taste and wanted me to grow more trees to provide enough lemons for their hotel partners, so that they can make "pink lemon sorbet" for hotel visitors. Unfortunately it is not wise to grow PVE commercially, it is a waste of land.
I've never tasted NZL, Villafranca or Femminello Siracusano 2KR, I hope you enjoy them.
