Hybrid varieties used in cold regions
Vidal is a hybrid variety used in Ontario's Icewine. The provincial certifying agencies explain that hybrid varieties have been developed to cope with winter cold and disease, with examples suited to the region. Do not judge solely by vinifera, but consider both variety and region together.
Harvesting fruit that has naturally frozen
According to Ontario icewine regulations, grapes must be naturally frozen on the vine, harvested at -8°C or below, and immediately pressed in a continuous process. This differs from freezing in a freezer or simply late harvest. Verify not only the grape variety but also records of harvest and pressing.
Variety and certification are different pieces of information.
Vidal is a hybrid variety permitted for VQA Icewine, but using Vidal does not automatically make Icewine. The method of natural freezing and other certification conditions must be met. If you separate the raw ingredient name, Vidal, from the product label, Icewine, you can organize the information on the label.

Understanding sources about Vidal: hybrid varieties and the natural freezing method
The document below organizes learning material based on the sources listed at the end. Before answering the questions, make sure you understand what is being compared between the two columns.
This is a summary of regions, grape varieties, and methods as confirmed in the source. Where specific products or vintages are referenced, the target is clearly stated.

|---|---|---|
| What is indicated | Hybrid varieties among the ingredients. | Wine meeting conditions such as harvest and method of production |
| Freezing | Cannot be determined from grape variety name alone | Natural freezing on the vine |
| Harvest & pressing | Check the individual steps in the process | Harvested at a temperature below −8°C and pressed immediately |

What does the Vidal label specifically indicate?
Vidal is the name of the grape variety used. Whether it is made as Icewine or not should be determined separately by checking the product label and the harvest/pressing conditions. Do not assume natural freezing and certification has been met just from a grape name—read and distinguish between the different types of information needed.
What is the required freezing process for Ontario icewine?
Ontario’s regulations require the grapes to be naturally frozen on the vine. Artificial freezing or just late harvesting cannot be described in the same way. Understanding the condition of the fruit at harvest is key to understanding the production method.
What harvest and pressing conditions are set in the regulations?
The regulations specify that the fruit, naturally frozen, must be harvested at minus 8°C or below and pressed immediately in a continuous process. This figure is interpreted in the context of the Ontario system. Do not confuse it with the cold tolerance of grape varieties or the serving temperature of finished wine.
