Hardness
Hardness defines how firm a bait becomes after processing.
It influences durability, breakdown speed, and how the bait performs in water.
What is hardness
Hardness refers to the resistance of a bait to pressure and water.
It determines how well the bait maintains its shape and how quickly it begins to soften and break down.
Effect of boiling
Boiling activates binders and proteins, setting the structure of the bait.
Longer boiling generally increases hardness, creating a more compact and durable boilie.
Shorter boiling results in a softer bait with higher activity but reduced stability.
Effect of drying
Drying removes moisture from the bait, increasing firmness over time.
Air-dried bait becomes harder as water evaporates, while freezer bait remains softer due to retained moisture.
Drying plays a major role in final hardness and shelf life.
Hardness vs leakage trade-off
Hardness and leakage are directly connected.
Hard bait:
• Slower water penetration
• Reduced leakage
• Longer durability
Soft bait:
• Faster activation
• Increased leakage
• Shorter lifespan
The goal is controlled balance between stability and activity.
Effect on bait performance
Hardness influences how the bait performs in different situations.
Hard bait is more resistant to nuisance fish and long sessions.
Softer bait is more active and suitable for short sessions or quick attraction.
Common mistakes
Hardness issues are often caused by poor balance.
Common mistakes include:
• Overboiling → overly hard, inactive bait
• Underdrying → unstable bait
• Too many binders → excessive firmness
• Too many solubles → overly soft structure
Balancing hardness
Hardness must be balanced with other factors.
It should work together with:
• Binding strength → structure
• Solubles → activity
• Birdfoods → texture
• Liquids → hydration
The goal is a bait that holds together while still performing effectively.
In Boilie Maker Studio
Hardness is evaluated as a result of ingredient composition and processing.
The system analyzes:
• Binding strength
• Boiling conditions
• Drying behaviour
• Interaction with solubles and liquids
This allows accurate prediction of bait firmness and performance.
