How much pure alcohol in a glass of wine?

Lord Avebury asked Her Majesty’s Government:
Why the Department of Health leaflet How Much is Too Much? updated in October states that one small glass of wine containing 125 millilitres (ml) contains one unit of alcohol, when that amount of most table wines containing 13.5 per cent alcohol would be 1.7 units of alcohol; and why the department's web page on alcohol and health states that a 175 ml glass of wine contains two units, when the figure for most table wines is 2.36 units. [HL141]
The Parliamentary Under-Secretary of State, Department of Health (Lord Darzi of Denham): In the leaflet How Much is Too Much? the information that a 125 millilitre (ml) glass of wine contains around one unit of alcohol is inaccurate. A 125 ml glass of wine containing 13 per cent alcohol contains 1.6 units of alcohol. The department is committed to ensuring that everyone has accurate information so that they can estimate how much they really drink. In addition, as the noble Lord pointed out, the entry on the alcohol and health web page was inaccurate and has now been corrected. I would like to thank the noble Lord for bringing this to the Secretary of State’s attention.
