Episode 48: Iowa

Iowa may be a state that is associated in pop culture with endless waves of corn and soybeans, but the Hawkeye State has a vibrant wine culture too! Our first wine from this state that we will be looking at is the Iowa Candleglow White, from Tassel Ridge Winery, located in Leighton. The Candleglow White is a non-vintage dry white blend of La Crescent, Brianna, and Edelweiss grapes grown in Mahaska County, Iowa.

We have met La Crescent before during our exploration of the Tectonic from Iapetus Winery, but Edelweiss and Brianna are new varietals to the Make America Grape Again podcast. Like La Crescent, both Edelweiss and Brianna are complex, cold-hardy, French-American hybrid varietals. Both of these varietals came into being as a result of Elmer Swenson, and the University of Minnesota’s cold-hearty grape breeding program. Indeed, the genetic history of these grapes is pretty tangled, as seen in the diagram below.

The Pedigree of Brianna, like that of many complex mixed-heritage varietals, is mindbogglingly complex.

Growing wine in Iowa is filled with challenges.  Warm summer days can create conditions conducive to promote fungal vine diseases, while the extreme cold nights of winter can kill many other grape vines; this is why there are relatively few plantings of Vitis vinifera in Iowa, versus complex hybrids and native American varietals.

There was some viticulture in Iowa prior to prohibition, but records are spotty at best.  Prior to 2000, there were only thirteen wineries in the state, and eleven of them were in the Amana colonies, which was a religious communal society which had originated in Germany and settled in Iowa in the 1850s.  These wineries benefited by a native wine law which passed after Repeal, which allowed them to sell wines to anyone.  It was in the year 2000 when the Iowa Grape Growers Association was formed, and this group wasted no time in creating an action plan for the growth of the wine industry in the state.

The group decided that the three main things which were needed were favorable legislation and basic education relating to viticulture.  Within a year, the team had gained the involvement of the Iowa Department of Education involved, along with some basic assistance from Iowa State University.  A year later, funding for viticultural research and promotion became a reality with a five percent tax on wine.  In 2003, the team created a ten-year plan, with the aid of interested parties, and within a mere four years, 62 wineries had emerged in Iowa.

 Today, despite the challenges of growing in the harsh conditions of the high plains, the state of Iowa contains 100 commercial wineries, with more than 300 vineyards that cover approximately 1,200 acres. There are no American Viticultural Areas that are solely in Iowa, but Northeastern Iowa is included within the area covered by the Upper Mississippi Valley AVA.

This bottle was kindly provided to the podcast by Greg Gonnerman of Laramita Cellars, who also guest-starred in this episode.  He acquired it from the Tasting Room directly.
