More than 6,000 cases of the beers have been supplied to the retailer, to meet customer demand for new and more unusual beers.
Plum Porter is a dark, sweet, full-bodied porter with background notes of damson and blackcurrant, followed by the fruitiness of the plum in flavour and aroma. A perfect, warming beer for the winter season, says the brewer.
Citrus is a premium golden beer with a light, natural grapefruit flavour, producing a subtle citrus aftertaste.
Both of these beers will be available in 500ml bottles in Morrisons stores nationwide until October 25.
