Kew Gold has sold more per outlet than any other brand launches over the last year, the latest Nielsen figures show.
And re-launched Young's Bitter is the second most significant launch across the bottled-conditioned ales sector.
Chris Lewis, director of marketing at Wells & Young's, said: "To have claimed almost 15% of the market within just a few months is fantastic . It's good news for retailers, too, as there is a higher price point for bottled-conditioned beers.
"This 'super-premium' sector's share of the whole single bottled ale market is continuing to increase and now equates to 5.8%."??? The bottle conditioned ale sector is the fastest growing sector in the bottled ales category in the off-trade, growing 15% in value and adding over ú1.9m to the PBA category.
