 Some wineries also feature live music and theatrical performances in the vineyard during the summer months.Visitors come during the coldest months of the year (usually December to February) to watch some varieties of grapes being harvested and pressed outdoors in the vineyard as part of the process of creating the sweetest, and among the most expensive, wine on earth – ice wine.A few Niagara Peninsula wineries have won the most prestigious international awards for their ice wine products, many of which are only available from the vintner.
