Point of order, Mr Speaker:
Perugia categorically does NOT produce world-class chocolate. It is famous as the home of the Perugina company (now owned by Nestle), which produces mass-market chocolate. Perugina's chocolate is of decent but unspectacular quality - in much the same way as Cadbury chocolate in the UK or even Hershey in the US.
But "world-class" it most certainly is not. For world-class chocolate in Italy, one has to look to the mighty Amedei in Pontedera, Tuscany. Amedei sources its cacao from individual highly-vetted estates across the world, and almost exclusively uses only Trinitario or Criollo beans - rather than the far blander (but higher-yield) Forastero variety used by virtually every mass-market chocolate manufacturer (including Perugina).
I've visited Amedei and and met Cecilia Tessieri (the founder and master-chocolatier of the company) - as well as several other of the most prestigious chocolate conchers/manufacturers in the world. Perugina is not one of them.
As you might tell, I'm quite interested in high-quality chocolate
