Chenin Blanc: Understanding Harvest, Sweetness/Dryness, and Old Vine Labels
Compare the dry, sweet, and sparkling styles of the Loire with the diversity of South African whites. Reading sequentially through harvest timing, winemaking, and vine age, explain the differences that arise from the same grape.
Questions for this course
Is it possible to determine the depth or sweetness of flavor from ‘old vine Chenin’ alone?
Before you start reading, briefly jot down your thoughts. You will rephrase them at the end.

Changing the use by choosing the time of harvest
Loire Chenin is used for dry whites, sparkling, and sweet wines. InterLoire describes fruit harvested earlier in the season as used for dry and sparkling wines, and fruit harvested later used for sweet wines. However, knowing a late harvest alone does not determine final residual sugar. Continue reading fruit condition and fermentation control.
There is a range even within dry wines.
South Africa’s Chenin Blanc Association introduces styles from fresh and vibrant to those with depth from barrel fermentation. After checking whether a wine is sweet or dry, you can compare vessels, lees contact, and aging. The term ‘Chenin’ does not stand for a single flavor profile.
What old vine certification shows.
South Africa’s Old Vine Project certifies vineyards planted over 35 years ago and marks the planting year on the seal. It’s important to distinguish between initiatives to protect old vines and the evaluation of individual wine flavor. Even if you can trace vine planting from the certification, information on new oak percentage or residual sugar requires separate documentation.
What to align and what to compare.

Chenin Blanc: Interpreting data on harvest, sweetness level, and old vine labeling
Using two hypothetical dry whites made from old vine Chenin, discuss vine age and winemaking separately.
This is a hypothetical example for learning. Both are 2024 wines made from Chenin Blanc planted in the same vineyard in 1978.
This is not an officially certified brand. The residual sugar content of the finished product is not indicated.
| Item | A | B |
|---|---|---|
| Raw material | Harvested relatively early to preserve acidity. | Harvested later than A. |
| Production method. | Make the base wine and conduct a second fermentation in bottle. | Fermented in barrel to produce a still white wine |
| Planting year | 1978 | 1978 |

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.
What does the number 1978 indicate?
This refers to the year the vineyard was planted. It does not mean the 2024 wine was matured from 1978.
Which process is directly related to the bubbles in A?
At A, after the base wine, secondary fermentation takes place in the bottle. Old vines alone do not produce sparkling wine.
Can B be determined to be sweet?
The sugars at harvest and the residual sugars after fermentation are different. Harvesting later or using only barrel fermentation does not necessarily result in a sweet wine.

Explain in your own words
For two wines made from fruit of the same old vines, explain their similarities and differences in production methods. Please provide a reason why the taste is not necessarily identical even when the vine age is the same.
Check after writing
- Did they separate planting year and vintage?
- Did you explain the differences between sparkling and still white wines?
- Are you being conclusive about taste or quality just from the age of the vines?
