The necessity of wine supply chain traceability system is inevitable due to increase in counterfeiting, adulteration, and use of excessive preservatives and hazardous chemicals. To overcome these issues, wine industry is in need of a traceability system which enables a consumer to verify the composition of each batch of wines from the grape growers to the retailers. However, most of the current systems are RFID and web based and thus it is possible to counterfeit stored information as required. This study proposes a blockchain based wine supply chain traceability system where every transaction is recorded as a block in the chain and is visible to the relevant participants. These blocks of information is immutable since any change to the recorded information will break the chain. In addition to providing quality information management framework, the proposed traceability system enables transparency, safety, and security in the overall process from the grape to the bottle.
