What most people describe as wine headaches (or a sulfite headache) is a reaction to bio-amines formed during the malolactic fermentation process in wine making from pressed grapes, and not levels of sulfites in wine making kits. Most wine making kits do not go through a malolactic fermentation process, and do not have significant levels of bio-amines created. (more on malolactic fermentation in a future post)
