To add to what the sibiling commenters had said. I was born in the village in part of the world where there are strong 4 seasons. So winters are full (less lately) of snow and bellow 0 celsius. People here store large veraety of vegetables over the winter. Potatoes, pumpkins, onions, garlics and others are stored as is as I remember. Other which could not be stored for long raw are fermented and kept in glass jars, it is called ‘turšija’ here :) Then there are grains and legumes and beans and dried stuff and you can easily thrive on localy sourced food even during winter.
