The move is being made after research for the company showed widespread ignorance of some basic wine facts among shoppers.
The supermarket group is also expanding its own-label offering to give consumers more choice across a wider range of purchasing occasions, and introducing 50cl bottles for the first time to encourage responsible consumption.
Morrisons research showed that 58% of customers think Chablis is a type of grape rather than a wine-producing region, while almost half believe Chardonnay is a region, not a grape variety.
Forty-three per cent failed to recognise that Beaujolais was a French region and 16% assumed Champagne was in Spain, Italy or Germany rather than France.
Morrisons said it was increasing the number of its in-store specialists to help shoppers navigate the range and learn more about choosing wine and food matching.
Wine development manager Arabella Woodrow MW said: “As more people stay in and host their own dinner parties, choosing wine can feel like a daunting prospect.
“This is why we are continuously perfecting our range, so that it is clear and easy to understand the difference between Bordeaux and Beaujolais.”?Morrisons has 437 stores.
