Budding/ripening
Yields
Vulnerabilities
Main growing challenge
Flavour
Structure
Early budding/ripening
Yields: limited to ensure ripeness
Vulnerable to: millerandage, downy and powdery mildew, bot, fan leaf and leafroll viruses, shrivelling and sunburn
Challenges:
- Ripens too quickly in warm conditions –> harvest earlier so lacks aromatic intensity
