Filbert's Old Time Quality Blueberry Soda comes in a squat 12 fl oz (355 mL) glass bottle with a colorful label depicting a wooden barrel. It reads, "Filbert's Old Time Quality Blueberry Soda." The cap also says, "Filbert's Old-Time Quality Beverages. Since 1926."
The deep purple-blue liquid gives a tiny hiss upon opening and a quiet pour. As a few bubbles surface, the scent is of light blueberry. Sip it and find it has a moderate mouthfeel, slight thickness, and extremely light carbonation. The taste is of a subtle, natural blueberry balanced with lively citrus. There's moderate acid with a bit of dryness in its finish. This is a fairly smooth beverage for those looking for an interesting soda.
