An object of the invention is to provide a beer-like effervescent beverage which exhibits low turbidity and superior clarity, while offering excellent foam retention and flavor. As a result of intensive research of methods capable of reducing the increase in turbidity resulting from the combination of a water-soluble soy polysaccharide and hops during the production of beer-like effervescent beverages, it was discovered that the use of a silicon dioxide with a purity of at least 98% as a filtration assistant during the filtration step was very effective.本發明之課題在於提供泡沫持久性、風味優異而且低濁度的清澈性高的類啤酒發泡性飲料。努力研究在製造類啤酒發泡性飲料時使由於將水溶性大豆多糖類與忽布予以併用而增高的濁度降低的方法，結果發現在過濾步驟使用純度98%以上的二氧化矽於過濾助劑為有效。
