SCHEDULED PUNCH
Punching can also be done automatically on a schedule. Typically, a punch is performed every 3 to 12 hours
depending on winemaker preference. This is the preferred mode as the fermentation can be left entirely
unattended. The scheduled punch ensures that the punch is performed consistently.
Punches start at midnight and are then spaced at equal intervals over 24 hours. The follows table tells you the time
each punch will occur. For example if you select 4 punch per day, they will occur at midnight, 6 am, noon, and 6
pm. Note that if you select say 2 punches and you set this before noon then, the first scheduled punch will happen
at noon not midnight. The next at midnight and so on.

The number of punches per day is determined by the winemaker. The default value of 4 per day is correct for most
varietals. Very tannic grapes such as Petite syrah and Cabernet sauvignon can benefit for a more aggressive punch
schedule whereas thin-skinned grapes such as Pinot noir should be punched less frequently. Note the in the
