Alessi Boston Shaker - It consists of two parts which fit one into the other; a large metal tumbler in this case made of 18/10 stainless steel rendered flexible by a special strain-hardening operation, and a tumbler in very thick glass. The tumbler (preferably the one in steel) can also be used as a mixing glass (for cocktails with dry liqueurs, while the shaker is used for dense liqueurs), together with the whisk for bars. This is considered to be the most professional type of shaker. Legend has it that it was created towards the end of the 19th century by an unknown barman on board a Trans-Atlantic liner sailing between Boston and Europe. The project comes from an in-depth investigation into professional tools for bars and for wines carried out in the second half of the 70s with Alberto Gozzi of the Scuola Alberghiera, the training school for the hotel trade, in Stresa. He has since worked together with Alessi on many projects, mainly for the hotel trade.
