Winter boilies: how to make a bait for cold water
Below about 8 °C carp feed little and digest slowly. A winter boilie is smaller, easier to digest and leaks attraction fast, because a bait that sits unnoticed for days does nothing.
What changes in the water
In cold water the fish's metabolism slows right down. Oils thicken and stop carrying flavour, heavy fishmeal sits in the gut for days, and the window in which a carp decides to pick up a bait is short. What works is a bait that releases signals quickly and leaves the gut fast.
Use more of
- Predigested fishmeal, krill and hydrolysates: easy to digest and strongly attractive
- Liquid attractors such as liver hydrolysate and corn steep liquor, which keep leaking in cold water
- Milk powders and yeast for soluble, savoury signals
Use less of
- Fat and oils: they set in cold water and slow digestion
- Coarse, heavy base mixes that take days to break down

Questions about Winter boilies
What is the best boilie for winter?
One that is small, digestible and leaks attraction quickly: predigested or high-grade fishmeal, krill, milk proteins and liquid hydrolysates, with very little added oil. Bright hookbaits also help in clear winter water.
Should I use less bait in winter?
Yes. Carp need far less food in cold water, so a handful of baits or a single hookbait with a small PVA bag often outfishes a big bed of bait.

- Easing Predigested fishmeal back down to its guideline maximum of 15% — it's currently running at 25% — should keep texture, cost and palatability on track without losing what this ingredient brings to the mix.
