Please bring any of the items listed below, to be set out on a table, be tasted and feasted on during the night – and maybe for the next few days.
The conference will take place in the middle of Spring in a Greek Island, so it could be either warm with temperatures in the mid to high twenties (centigrade) or humidity at nights. So, bring a wide range of clothing to cover all eventualities.

Beach in front of Delfinia Hotel and bungalows
As we are talking for an island on the north of Aegean sea it will be preferable to be prepared for all weather types! At nights humidity from the sea will be sensed!
