“The price point remains among the lowest in the country for comparable events,” expo creator Alex Pappajohn said. “We’ll have a lot of high-quality juice on the floor.”

Many of the wineries will be pouring six or more wines. Among them is Lake Anna Winery, which is planning to bring as many as nine, including recently released Essensual, a 100 percent vidal blanc dessert-type wine made from grapes that were purposely frozen. Wines made from grapes frozen on the vine are usually called ice wines.

And they are sweet. Sometimes very sweet.

“Essensual is what I call a faux ice wine or a cyroextracted wine,” Lake Anna winemaker Graham Bell said. “In Virginia, temperatures are not consistent enough in winter to freeze grapes on the vine as is traditionally done in more northern latitudes, so we have to resort to a commercial freezer plant.”

The process for making Essensual is the same as that for a traditional ice wine, Bell said.

“The grapes are pressed as they are thawing, and only the sweetest most flavorful juice is extracted, leaving significant water still frozen in the pulp. The initial grapes are more concentrated in a traditional ice wine because of hanging on the vine for so long, hence, a generally more intense and more expensive dessert wine.”
