Building Skill and Confidence in Your Wine-Tasting Palate

August 26, 2019

Maureen Moroney

I recently had the privilege of attending the International Cold Climate Wine Competition (ICCWC) as a judge. The competition was organized by the Minnesota Grape Growers Association and the University of Minnesota, and featured more than 300 wines from cold-climate varieties, plus 24 judges and numerous hard-working volunteers.

Earlier in my wine-world career, the idea of serving as a judge at a wine competition would have seemed inconceivable to me. Now I have three under my belt, and I don’t find it at all uncomfortable or stressful. Read more about Building Skill and Confidence in Your Wine-Tasting Palate

A Recap: Summer in the Lab from our Students

August 20, 2019

Sam Anderson

Time flies by when you’re having fun! The fall semester begins very shortly for ISU students, including myself, an undergraduate who has been working in the Midwest Grape and Wine Industry Institute’s laboratory this summer. The past three months here have been filled with learning, research projects, some field time, and lots of wine analysis in the lab. Read more about A Recap: Summer in the Lab from our Students

Variation within and among analytical methods for wine testing

July 2, 2019

Maureen Moroney

One question that comes up often – whether in the course of my own work, from other researchers and lab techs, or from wine industry members doing their own in-house wine analysis – is which method is “best” and gives the “right” answer.

This is a complicated topic. It touches on ideas related to sources of error, types of variation, method validation, instrument performance, staff training, quality assurance, critical thresholds, and impact on winemaking decisions, just to name a few.

Della Toffola Equipment

July 1, 2019

The Iowa Wine Growers Association summer field day featured renowned viticulturist, Dr. Richard Smart, well known for his book “Sunlight into Wine”. He covered popular topics of canopy management and grapevine trunk disease but also discussed a new winemaking technology that he was involved with developing. Accentuated Cut Edges (ACE) is a maceration technique aimed at improving red wine phenolics by fragmenting the grape berry skins more than normal crushing. Read more about Della Toffola Equipment
