## How to Acquire

Put Grapes into an Extraction Press, right-click it and press the Press button. This will put grapejuice in the press (shown as a bar); two full pressings will fill the press with juice.

With an empty bucket selected or an empty barrel (or a barrel partially filled with grapejuice), right-click the press to fill the bucket or barrel with juice.

## Use

Grapejuice is placed in demijohns to ferment into Wine. Grapejuice will not ferment if placed in a barrel. If left in the press or any container (other than the demijohn) for 5 hours, it will turn into Stale Grapejuice which eventually turns into Vinegar.

If you add more grapejuice later, the fermentation doesn't reset but averages.

In other words, if you have a barrel with Ae liters of grape-juice which will take De units of time to ferment, and put in An liters of fresh grape-juice which will take Dn units of time to ferment, the time it will take for the mixture to complete will be ((De * Ae) + (Dn * An)) / (Ae + An).

## Quality

The quality of the grapejuice depends on the quality of the extraction press and the averaged qualities of the pressed grapes.
