The biggest difference is the removal of the bitter aftertaste, with its occasional hint of aluminum and anlingering alcohol taste. The flavors themselves are also dramatically different and more powerful — all 13 Truly varieties were enhanced to be "bigger, brighter, and bolder," O'Neill said.
O'Neill said the reformulation took about three months and involved a process with more than 130 different trial recipes — at least 10 for each of Truly's 13 flavors — and constant taste testing before arriving at the final product. While O'Neill and select members of her team were sampling multiple times each day, she would also hold regular full office tastings at 7 a.m. on Monday, Wednesday, and Friday.
