The House of Commons spent more than £1.4 million on alcohol to sell in Palace of Westminster bars in 2012 and 2013, according to the Times.
The bill is equivalent to spending of £1,100 per MP every year.
A Freedom of Information request by the newspaper revealed that parliamentary authorities bought nearly 50,000 bottles of House of Commons sauvignon, more than 26,000 of house merlot and more than 33,000 pints of guest ale.
More than 8,500 bottles of champagne were purchased alongside over 2,100 bottles of Speaker John Bercow's whiskey.
According to the newspaper, spending in Commons bars has gradually increased over the past three years, from just over £222,000 in April 2011 to more than £249,000 in the year to April last year, but this may reflect rising prices.

The figures may lead to further questions over Parliament's supposed drinking culture, which was laid bare in the trial of Tory MP Nigel Evans, who was cleared of sex offences.
The Commons booze culture also hit the headlines when Eric Joyce was forced to resign the Labour whip in 2012 after fighting Tory MPs in a Commons bar.
Most of the alcohol will have been drunk by the 650 MPs, 760 peers, and thousands of staff and parliamentary workers in the Palace of Westminster.
