Licensees on the Isle of Man can expect to enjoy three months' worth of business in just two weeks, thanks to centenary celebrations of the island's TT bike race bonanza which ends this weekend.
Manx hosts are looking forward to huge returns from the annual event, which has seen an influx of more than 60,000 bike fans on the tiny island.
Its three breweries experienced record output as doubling of the usual attendance led to unprecedented demand in pubs and tented bars.
Bushy's Brewery, which is running a special tented bar on the promenade of the capital, Douglas, says it is selling up to 10,000 pints a day.
"We've doubled brewing capacity in an attempt to satisfy demand from the 2,000 drinkers the complex can hold," said brewery boss Martin Brunnschweiler.
"Those pubs which are in the best locations will do 12 weeks' business in a fortnight. There were initial concerns that the island may run out of beer, but I think we'll manage," he added.
The 46 managed pubs operated by Heron & Brearley, the retail arm of the island's main brewer Okells, will double their takings on average.
One strategically-sited venue is on course to take more than £100,000, while another pub will see takings soar to £35,000 per week.
Heron & Brearley operations manager Chris Taggart said: "Most pubs will at least double their takings but others will enjoy a spectacular fortnight."
