Rkatsiteli: The treatment of grape skins distinguishes white and amber styles.

Kakheti's white varieties are compared between those made by separating juice and those fermented and aged together with skins and seeds. Also read the blend regulations for Tsinandali and distinguish grape varieties, vessels, and appellations.

Rkatsiteli / Learn by grape

Update date: 2026-09-23

Indigenous white varieties rooted in Kakheti

Rkatsiteli is a white grape originating from Kakheti in eastern Georgia and is also grown in Kartli. It preserves acidity well even as sugars accumulate, making it suitable for different winemaking styles. The National Wine Agency highlights delicate white aromas from juice-focused winemaking and the powerful structure and tannins from traditional qvevri techniques. Even with the same variety name, skin treatment may differ.

Time in contact with skins and seeds

In traditional Kakheti qvevri winemaking, the juice, skins, and seeds are all placed in the vessel, and even after fermentation, they remain in contact. This process produces amber wines with color and astringency even from white grapes. Qvevri refers to these clay vessels. When comparing production methods, if you check not only the vessel name but also what is included and when it is removed, you can explain differences in extraction.

Tsinandali’s whites and grape proportions

The registered specification for Tsinandali I checked specifies the white as at least 85% Rkatsiteli and up to 15% Kakhuri Mtsvane. This does not mean the latter must always make up 15%. The appellation also allows for Saperavi-based reds. Rkatsiteli is the grape variety, while Tsinandali is the name for the region and prescribed production method. Looking at both the label and composition information helps avoid confusing a single variety explanation with the whole appellation's description.

Reading Rkatsiteli resources: differentiating white and amber by the treatment of the grape skins.

Using two fictional winemaking records, explain the relationship between white grapes and astringency.

This is a hypothetical example for learning. It does not represent any specific product or appellation certification.

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 should you check regarding B’s tannin?
B is white grape Rkatsiteli, but the record notes skin and seed contact. Compounds are extracted by this contact, so a tannic result can be described. There is no need to assume red grapes were used.

What are the conditions that differ between A and B?
Although the grape variety is the same, both the vessel and the treatment of skins and seeds have changed simultaneously. From only these two examples, you cannot definitively attribute the difference in the final wine to the effect of clay. You also need to consider separate factors such as skin contact.

Can A be certified as a Tsinandali white?
A blend of 100% Rkatsiteli meets the requirement of at least 85%. However, based on the table, it’s unclear whether the grapes come from the specified area or if the designated production method is used. The maximum of 15% permitted for Kakhuri Mtsvane is not a minimum usage requirement.

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 the treatment of grape skins in order for A and B, and give a reason why the color or tannin of B cannot be explained solely by the material of the vessel.

Check after writing

  • Did you indicate the processes using the skins and seeds of white grapes?
  • Did you distinguish container material and skin contact?
  • Are you deducing Tsinandali’s certification without documentation?
