Subj: proof changes in Kahlua

Dear Mr Shea:

I write to inquire about the changes to the alcohol by volume (ABV) / proof changes in Kahlua’s main product, from 53 proof to 40 proof. Having been purchasing Kahlua for about 15 years, the change in the product’s alcohol content came as quite a surprise. Some questions:

1) Is this a change to be made in all states?
2) In what states has it already been made?
3) Will prices be going down for the lower proof beverage?
4) Will Kahlua publicize this change at any point?
5) When will the www.kahlua.com web site be updated to reflect the lowered proof?
6) Is this change to encourage purchase of the new, high-proof “Kahlua Especial” product?

I very much appreciate your attention to my inquiry, and look forward to your response.

Sincerely,
my name and e-mail address included here
