Among the sweet fruit wines used in the present invention, the sweet fruit wine obtained from grapes as a raw material and subjected to fermentation and thermal aging treatment is used.

  Specific examples of the attractant include a sweet fruit wine derived from grapes called madilla wine or baked wine.

  Madilla wine is a wine that has been refined in the middle of the fermentation process of grape juice and then stored and aged under high temperature conditions (thermal aging treatment). Strictly speaking, “Madilla wine” refers to those produced on the island of Madeira in the Portuguese territory. However, in the present invention, regardless of the production area, the Madeira wine is substantially the same in terms of ingredients and properties. Those that can be regarded as equivalent are called Madira wines.

  In general, baked wine is a sweet fruit wine made from grapes as a raw material and subjected to thermal aging. It is basically the same as madilla wine or has a lot in common in terms of manufacturing method. Baked wine is also produced by using grapes as a raw material, strengthening alcohol during the fermentation process, and further subjecting to heat aging. The alcohol content of the baked wine thus obtained is usually 15% or higher, which is higher than the alcohol content of general wine. In addition, fermentation is stopped by the above-mentioned enhancement of alcohol, and decomposition of sugar is suppressed, so that a relatively large amount of sugar remains, so that it has a characteristic that sweetness is stronger than normal wine.

  Such Madilla wine and baked wine are available from the market. Specific examples include “Mershan Baked Wine” (Kirin Kyowa Foods Co., Ltd.), “Adeka New Baked Wine” (Adeka Co., Ltd.), “Tokachi Wine Sylphy” (Ikeda Town Grape and Wine Research Institute), “Shan Mori Baked” Wine "(Morita Koshu Winery Co., Ltd.).
