I also tried to fix it with OwinMiddleware but failed.

My solution was to create an ActionFilterAttribute and register this at startup:

public partial class Startup : UmbracoDefaultOwinStartup
{
    public override void Configuration(IAppBuilder app)
    {
        GlobalFilters.Filters.Add(new CultureCookieFilter());
        base.Configuration(app);   
    }
}

public class CultureCookieFilter : ActionFilterAttribute
{
    private const string CULTURE_KEY = "X-Culture";

    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        if (filterContext.HttpContext.Request.Cookies[CULTURE_KEY] != null)
        {
            var langCookie = filterContext.HttpContext.Request.Cookies[CULTURE_KEY];
            if (langCookie != null)
            {
                var lang = langCookie.Value;
                Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo(lang);
                Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(lang);
            }
        }

        base.OnActionExecuting(filterContext);
    }
}
