Can you craft a compost within the winter? ...
Of course. However, sometimes even without turning it, which make it work faster, it will develop eventually; as everything breaks down at some time or another.
Yes you can. A properly "working" compost pile will breed it's own heat.
You can hold it indefinately before using it. If you quit turning and "feeding" it will quit working but will be fine until you are set to use it.

Answers: Composting is an exothermic reaction, it creates warmness so it will go even within winter, just slower.

A rule of thumb on C:N ratio is gross roughly 1/4 - 1/2 of the pile green nitrogen materials and 1/2 - 3/4 brown carbon materials.
Smell and temperature are the best appraise of your composts activity plane.
1 - If it smells fresh like turned soil it is working properly.
2 - If you achieve it to wet it will switch on to decompose anaerobically and produce hydrogen sulfide, the rotten egg smell. The best piece is to turn it and get nouns in. Possibly division in fresh dry ingredients to hold your attention excess moisture.
3 - If the pile has an ammonia odor, you hold too much green material (grass clippings, food leftovers, green plant material) and not enough brown (dry leaves, woody prunings, pine needles, dried out plants, saw dust). Add more brown substance or a shovel of soil and turn it.
4 - If it just sits &/or you see ants next the pile must be to dry. Everything should be moist but there should be nought dripping. If you piled it to dry, its own heat dried it or the summer weather dried it next you must turn it rewetting the layers as you progress.
5 - If it just sits in attendance and wonĄŻt heat up despite person moist you have to copious browns. Too much carbon prevents the pile from heating. Go to a coffee shop and capture some coffee grounds, any grain, kernel or meal is a honourable source of nitrogen. Add some grass clippings in adulterate layers or bring back a neighbor to donate kitchen scraps.
