What becomes concentrated through freezing, and what is shown on the label

Compare natural freezing in Germany and Canada, and differentiate between the raw material conditions and final product values.

Questions for this course

If you know the sugar content of the juice, can you also know the sweetness of the finished wine?

Before you start reading, briefly jot down your thoughts. You will rephrase them at the end.

What becomes concentrated through freezing, and what is shown on the label: Read the material

Read the document below, first write your own thoughts, then answer the questions. After answering, compare with the explanation and try to revise your response.

The official documents have been summarized for study purposes. The producer's figures refer to the stated label and vintage, and do not indicate country-wide regulations.

Information not included in the table has not been confirmed. You can check the original explanation and applicability in articles on each country and in the listed sources at the end.

Subject	What to check in the documentation	Conditions for distinguishing by reading
German Eiswein	Pressing grapes while still naturally frozen	Confirm the conditions of ingredient juice
BC VQA Icewine	Each pressed juice must be at least 32 Brix.	The juice in the fermentation vessel averages over 35 Brix.
finished wine	There are no measurements of residual sugar or acidity in this table.	Impression of sweetness not yet assessed

Initial hypothesis

Each hypothesis or reflection can be up to 2,000 characters. You can save your answers even if you only select an option.

1. In BC, if the juice from each pressing is 32 Brix, does that alone satisfy the table's sugar content conditions?QualifiesAlso confirm if the fermentation vessel contains an average of 35 Brix or moreit meets the requirement if the finished product has residual sugar of 32 g/LReturn to unanswered

2. If you apply a juice record of 35 Brix to describe the finished wine?Write as 35g/L residual sugarSugar and acidity measurement is not required.Indicated as a value for the juice; research residual sugar in the finished wine separatelyReturn to unanswered

3. Is it correct to transfer this British Columbia regulation to the description for Ontario?Check regional regulations before describing them.No conditions apply, as it is within Canada.If the grape variety is the same, use it.Return to unanswered

ReviewAfter answering the question, how did you change your initial thoughts? Write down the statement that supported your decision, as well as one piece of information you still wish to confirm.

Read the explanation for each question

By answering in the selection field, you can compare your answers and explanations using the top button. Freeform responses will not be automatically graded.

If each press juice in BC is 32 Brix, does that alone satisfy the sugar level requirement in the table?
Minimum value for each pressed juice and the average in fermentation vessels are separate requirements. Just the number 32 by itself does not confirm satisfaction of the average 35 Brix requirement.

If you use a must record of 35 Brix to describe the finished wine, what does it mean?
Brix is a measure of sugar content in juice, while residual sugar in finished wine is given in g/L—they describe different things and use different units. Since sugar is consumed during fermentation, you cannot simply transfer the Brix number from juice to the finished wine.

Should this BC regulation be shifted to the Ontario description?
Check the scope of an appellation, including the state or region. Explaining the shared method of natural freezing is different from applying a specific regulation’s numerical values to other states.

Practice exercises in comparison

Is it possible to judge the sweetness or quality of two wines as the same based only on the shared factor of natural freezing?

Read examples of organizing comparisons

Conditions for Comparison	German Eiswein	Canada/BC VQA Icewine
Common process	Grapes that have frozen naturally on the vine are pressed while still frozen.	Grapes that have frozen naturally on the vine are pressed while still frozen.
Concentration of the raw material	A portion of the water is left as ice to extract concentrated juice.	Similarly, separate ice from concentrated juice.
How to read designations for appellations	Check criteria such as must weight for Prädikat.	Check the provincial regulations of BC for freezing/pressing and must sugar content requirements.
Target of the numbers	The specific gravity of the ingredient juice and the residual sugar in the finished wine are different.	Brix in must and residual sugar g/L in finished wine are not equivalent.
Remaining differences in comparison	Grape variety, vineyard, vintage, acidity, residual sugar after fermentation.	Read the same item side by side. Do not apply BC’s regulations to other states.

This is an organized study tool based on the designated articles for this course. You can check specific facts and sources in each article.

Explain in your own words

Explain, in 200–400 characters, the shared processes for people buying German and BC Icewine, and which taste factors can't be determined from the label alone.

Check after writing

Did you note natural freezing on the vine and pressing while still frozen?
Did you distinguish between juice and finished wine, Brix and residual sugar g/L?
Check whether regulations are being indiscriminately applied across states or countries.

Reorganize using the comparison table

A comparison table listing processes and conditions lets you check for any missing explanations.

Even if the concentration method is the same, regional criteria must be considered individually.
