I came across Grandpa Lundquist's Christmas Soda at Cardullo's in Harvard Square earlier today. There is the typical Cardullo's markup ($3 for a 12 OZ glass bottle), but the soda is terrific. I would call it a spiced cola, and it had nice layers of flavors and wasn't cloyingly sweet at all. This one is a real winner.
Now has anyone seen Swedish Glögg syrup for sale around Boston?
