My Lords, as a doctor and a wine drinker, I have serious concerns about this amendment, particularly, for example, when it comes to the use of fine wine—I think there is broad understanding in the House of what that is—where, in every case, those bottles are labelled with the amount of alcohol. One has to accept that labelling bottles in this way does not change behaviour. We have had committees looking at behaviour change, and the only time we managed to induce behaviour change was with smoking—certainly never with labelling. That is the only time it happened and there were all sorts of reasons for that.
Much of the evidence for alcohol being harmful in minor doses is still dubious and, more importantly, there is real concern that a lot of the so-called evidence is not being put to the real test of whether it makes a difference to behaviour. I must say to the House that I think the noble Lord—I am afraid I do not know his name; my eyes are bad enough not to have been able to see his name on the screen—is right that this is unworkable. It would probably do all sorts of untold damage to what is, for me and no doubt many others, a very fine drink. We need to look seriously at whether we can simply label all bottles.
I just remind the House that there is one amendment that I could have put down. In in vitro fertilisation, embryos are cultured in culture media, which are in fact commercially made and a commercial secret—nobody knows exactly what the composition of those media is. My laboratory is looking at this at the moment. It is really interesting, because some of the products in those culture media may indeed be quite dangerous in terms of epigenetic effects. To me, that seems far more important to regulate than what we are trying to do here with bottles of wine, which is probably not really workable.
