Chardonnay, gewürztraminer, moscato are white grape varieties. This page describes wine styles by variety and production area. Any below variety can give dry white wine or sweet white wine. Some varieties can be made bubbly or still.
If only one variety (chardonnay, gewürztraminer) is mentioned on the label, then the wine is called varietal and is named after the grape with a capital initial (Chardonnay, Gewürztraminer). Varietal wines primarily show the fruit: how the wines tastes much depends on the grape variety.
