The problem is to provide a beer-flavored drink having improved foam characteristics. The problem is solved by providing: a beer-flavored drink characterized in containing at least 0.25 mass% of a branched [alpha]-glucan mixture that (A) has glucose as a constituent sugar, (B) has a branched structure having a glucose polymerization degree of 1 or higher, the branched structure being linked, via a bond other than an [alpha]-1,4 bond, to a non-reducing terminal glucose residue positioned at one end of a linear glucan that is linked via an [alpha]-1,4 bond and has a glucose polymerization degree of 3 or higher, (C) forms isomaltose by isomaltodextranase digestion, the isomaltose being formed in an amount of 25-50 mass% relative to the solids of the product of digestion, and (D) has a water-soluble dietary fiber content of 40 mass% or higher as determined by high-performance liquid chromatography (enzyme-HPLC); and a method for producing the beer-flavored drink.本發明係以提供改善泡沫特性之啤酒口味飲料為課題者,其特徵為含有(A)將葡萄糖作為構成糖、(B)具有位於介著α-1,4鍵進行連結的葡萄糖聚合度3以上之直鏈狀葡聚醣的一端之於非還原末端葡萄糖殘基介著α-1,4鍵以外鍵結進行連結的葡萄糖聚合度1以上之分支結構、(C)藉由異麥芽葡聚醣酶消化,生成消化物的固體成分單位下為25質量%以上50質量%以下之異麥芽糖,且(D)藉由高速液體色譜儀法(酶-HPLC法)所求得之水溶性食物纖維含量為40質量%以上之分支α-葡聚醣混合物以0.25質量%以上含有之啤酒口味飲料及其製造方法。
