GROM - Il gelato come una volta

An Italian art

Grom is high quality gelateria founded in 2002 by Guido Martinetti and Federico Grom, whose idea was to produce a gelato made with absolute top quality raw materials.

The standards are strict: only fresh seasonal fruit, no colorings or artificial additives, spring water for sorbets and high-quality whole milk for gelato, free-range eggs and a selection of the best cocoas and coffees from central America.

  • The energy used in Italy comes from renewable sources
  • Actively supporting waste recycling
  • No more plastic, just Mater Bi: a completely biodegradable and compostable bio plastic
  • Paper is produced by forests managed responsibly
  • The R&D department is Mura Mura organic farm

Seasonal and fresh ingredients

Grom interprets gelato making following the tradition of the Italian gelateria: fresh whole milk, egg yolk, white cane sugar, and the best raw materials play a major role. A moderate use of cream as well as a careful balance of sugar allow them to always have a low fat content, refreshing and not cloying product.

A selection of seasonal flavours is available daily at Café Doney.
