The invention discloses an acetobacter strain (acetobacter sp. SJA-1) CGMCC No.3347 and an application thereof in seabuckthorn fruit vinegar production. The invention relates to an acetobacter strain and a method for producing seabuckthorn fruit vinegar by using the acetobacter strain. A separation source of the stain is naturally fermented seabuckthorn fruit vinegar mash. The strain is used in seabuckthorn fruit vinegar production with seabuckthorn fruit wine as a raw material. A colony has a regular shape, circular projections, a milky white color, and a glossy surface. With 5 days of plate culturing, the diameter of the colony is 0.1-0.2mm, and a transparent circle diameter is 0.5-1.0cm. The strain shows negative by Gram stain. A thallus has a size of (0.6-1.0)*(1.0-1.8)mum, a short rod shaped, and no spore. The strain obtained after separation and screening can be fully adapted to relatively high acidity of seabuckthorn fruit wine, a fermentation speed is high, acetic acid conversion rate is high, and acetic acid peroxidation reaction is less possible. When the acetobacter is used for producing seabuckthorn fruit vinegar, a sour taste is prominent, a fruit aroma is rich, and a unique seabuckthorn fruit vinegar style is provided.

The invention discloses a preparation method of a carambola wine.
