The process diagram gives the 8 steps to make a single bottle of wine. Overall, producing and transporting an eight-stage process one bottle of wine from the picking the grapes and ends with sending to the supermarket. 400 ripe grapes are needed to produce one bottle, and waste is produced at three stages of this process.
First, the grapes are picked and collected to be juiced. 400 grapes are needed to produce 300ml of juice during this process. The waste generated from the juicing is sent to be composted. After that, the grape juice is left to ferment for 2 weeks before being sent to be pressed. Unpress waste is then composted while the remaining 1000ml of liquid is sent through a filtration process. The filtering system also produces residual waste, which is similarly composted, while the liquid is sent to be stored in barrels.
After having aged in barrels for a period of time, the wine is ready to be bottled. In total, a single bottle contains 750ml of wine. Finally, once the wine has been bottled, it is ready to transport to the supermarket.
