## TL;DR

This paper presents the full genome sequence of a wine yeast strain used in Russian red wine production.

## Contribution

The study provides the first complete genome sequence of Saccharomyces cerevisiae I-25 from the Krasnodar region.

## Key findings

- The genome sequence of strain I-25 was fully characterized.
- The strain is used for producing regional red wines in Russia.

## Abstract

Wine yeast Saccharomyces cerevisiae strain I-25, isolated from yeast sediment formed after spontaneous fermentation of Cabernet Sauvignon grapes in the Krasnodar region, is used to produce regional red wines in Russia. To characterize its genetic properties and biotechnological potential, we obtained a complete genome sequence.

## Linked entities
