Merlyn is a Welsh cream liqueur from Penderyn. This is made from Welsh "malted barley spirit" and fresh cream.

I love being Welsh, but why can I buy this stuff cheaper in the US than I can back home?
Got given a bottle of this as a gift for Christmas. The best cream liqueur we've ever had.
My daughter & I LOVED the small sample bottle we tried so I'm about to order her a large bottle for her birthday surprise teat!
Not sticky sweet, balanced and creamy, wonderful over ice, love it.
This is like Baileys for grownups - you can taste the good quality liqueur under the sweet creamy flavour. Just lucious and not sickly sweet. Get some and drink it over ice. Mmm...
