A calendar she first published in the 1950s categorises days as "fruit", "flower", "leaf" or "root", according to the Moon and stars. Wine is best on fruit days, followed by flower, leaf and root days. The worst day is marked as "unfavourable" in the calendar.

Her theory is that wine is a living organism that responds to the Moon's rhythms in the same way that some people believe humans do. The so-called "lunar effect" has been widely dismissed as pseudo-science but its followers think that as the Moon exerts such a huge impact on the tides, it must follow that it affects the water in the human body and therefore human behaviour.Her theory is that wine is a living organism that responds to the Moon's rhythms in the same way that some people believe humans do.

The belief that wine can taste different depending on the day it's drunk is not as eccentric as it may sound. All wine experts tend to agree - although their theories on why vary.The belief that wine can taste different depending on the day it's drunk is not as eccentric as it may sound.

The biodynamic calendar is part of the wider concept of biodynamic farming, pioneered by Rudolf Steiner in the 1920s. The philosophy is similar to organic farming but a key difference is that planting and sowing is timed according to the moon.The biodynamic calendar is part of the wider concept of biodynamic farming, pioneered by Rudolf Steiner in the 1920s.

name="say"> Leaving aside the question of whether or not this is fact or fancy, I wonder why the wine critics allow themsleves to be manipulated in this way? Surely they should insist on a level playing field for all tastings. In fact, surely the wine needs to be tasted on good and bad days to get a clear picture. Who's to say that a wine that is excellent on a fruit day is not a shocker on an root day, while another wine which is not as good on the fruit day might be a more steady performer, still being satisfactory on an unfavourable day?Ray, Turku, Finland

I've been growing vegetables according to the lunar calendar for the past year (but without following other biodynamic practices), with fantastic results. Big yields, delicious flavour, a greater ability to resist pests and diseases than I would normally expect. There will always be sceptics who are happy to rubbish any ideas that challenge their view of the world, but have they actually tried them out themselves? Jane
The Moon creates tides because large masses of water are fluid, and free to be re-shaped. The effect is caused by the Moon's gravity, which has an equal effect upon *everything* all the time. The Moon's distance from a point on the Earth varies by a small percentage when is on the same or opposite side of the Earth from that point. People move around, facing towards or away from the Moon. We don't stand still, so the effect of its gravity upon our bodily fluids is entirely random. The fact that the Wine in a glass is pulled one way or the other by a miniscule fraction of a degree cannot affect its flavour, which is a function of its chemical composition. The ambient temperature might have an effect, both on people and on the fluid. The atmospheric pressure likewise - but that is less affected by the Moon than by weather patterns. In other words, its all rot.Robert, Minster, Kent
If this article had appeared on April 1st it would have made for even lighter reading. As a wine merchant for over 40 years, this story ranks highly in the preposterous stakes. I have always prayed before running a tasting and I have never had a bad one yet, so I argue that a Christian perspective is the way forward....Winelines, Sevenoaks
Given that research has established that simply stamping a higher price on a bottle of wine improves its taste, it's hardly surprising that telling someone it's going to taste better on Thursday has a similar effect.Ian Kemmish, Biggleswade, UK
This is very interesting and there is no doubt that the taste of wine is ephemeral and therefore metaphsyics probably play a part. but, atmospheric pressure as also mentioned above is key too. In this country we live 2/3rds of the year under low pressure and this can lead to wines tasting soupy and all rather the same sadly. Do you not find that all wine tastes better when drunk on French soil? Equally I recall being in a restaurant in the Alps with a Parisian friend and when it came to choosing the wine he was adamnant that it was not worth choosing anything too fine as the high altitude renders all wine towards the indifferent. So there are so many factors, but, that is what makes also for those fleeting incomparably memorable moments.master of reality, London
I've read these moon theories, and watched my own organic garden to see if there are any observable traits. I put any improvement in horticulture down to simple TLC of the soil and plants. If you "dig" deeper into biodynamic ideas, you will find all kinds of weird stuff, like burying cows horns stuffed with their own manure. Many followers of Steiner's ideas believe in fairies and goblins, and unaccountable "energies". If all this were true, we'd know about it by now, but it all remains esoteric, and to gain the knowledge, guess what, you have to pay for it.Alan Robinson, Bjerreby, Denmark
