About 600 people showed up on Sunday afternoon for the first-ever Summer Soda Tasting at Galco’s Soda Pop Shop in Highland Park, where the line of soda sippers stretched around the block. The event, which also served as a fundraiser for the Friends of the Southwest Museum Coalition, included the debut of White Rose, a cream-flavored soda inspired by a former soda and water bottling company that operated in Highland Park. The Rose Springs Water Co., which operated on Figueroa Street from about 1900 to the 1960s, introduced White Rose soda in the 1930s. A group of Highland Park designers updated the original White Rose label for the new cream soda, a 2,500-bottle, limited edition brew that will be sold at Galco’s. A portion of White Rose sales will be donated to the Friends of the Southwest Museum, which is seeking to reopen the Mount Washington museum.
