Preston-based wet-led pub company Amber Taverns enjoyed a like-for-like sales increase during the 12-day festive period of 16%.
The company, which has 81 pubs across northern England, the Midlands and north Wales, saw sales rise by 4.4% for the whole of December.
Actual sales in December were £3.6m net, an increase on last December of 23%.
Amber's most recent acquisition was the Black Bull in Doncaster, which it will continue to trade for a few weeks before commencing a major refit with a further investment of £300,000.
It will open its 82nd unit, the Bull in Morecambe on 29 January, following a £350,000 refit. And it is close to exchanging contracts on a further two properties in Staffordshire and the West Midlands.
Amber Taverns agreed a £24m funding deal with Lloyds Bank Wholesale Banking & Markets in October 2012.
Clive Preston, chairman of Amber Taverns, said: "Once again we have shown the viability and popularity of well run wet led pubs. We will add even more of the same to our existing estate over the year ahead as we continue to progress our strategy of building a quality pub portfolio."
