Temperatures begin to rise, but there is still a risk of frost.
The vines wake up and the buds swell, open up, and reveal tender green shoots.

In the vineyard, it's time to:

• Tie up
  The longest cane (the fruit cane) is attached to the lower guide wire, which supports it throughout the growing season.
• Replace vine stakes
  Broken wooden stakes and guide wires are replaced.
• Replant
  Dead vines are grubbed up and replaced with new ones.

In the cellar, it's time to:

• Continue preparing orders of recently-bottled vintages for shipment
• Top up barrels
