Lewis Road founder Peter Cullinane said the latest liqueur product was the company's first foray outside the supermarket and was a natural progression for the company.
He said the aim was to rival the likes of Bailey's or Irish Cream.
"If the Irish can do it, so can we," Cullinane said. "We're all about innovation and finding new ways to pay homage to our dairy heritage and this cream liqueur delivers on our mission."
The 700ml bottles would be distributed by beer brand Moa, who's chief executive Geoff Ross helped with production.
Lewis Road Creamery, which was founded in 2012, now produces butter, milks and creams, flavoured milks, ice-cream, custard and bread.
