Heather Cream was first produced in 1980 which makes it Scotland's Original Cream Liqueur. It is created from the marriage of two of Scotland's finest natural products, fresh double cream and single malt Scotch whisky.
I found a few articles online that mention a re-branding and launch of the revamped packaging look of Heather Cream in 2006, which might account for why didn't see it in the stores for a while. It doesn't necessarily explain why it's not available around here now, but it's a hardship I guess we'll just have to live with.
It's super-yummy as an after-dinner dessert drink, and superficially resembles Bailey's Irish Cream. "I highly recommend picking one up, if you have the means. So choice." (Name that 80s movie quote.)
Thus endeth the lesson. Amen.
