Cold water & virgins
<table border=0 cellpadding=2 cellspacing="0"><tr><td>
<pre>I like it. Good romantic stuff. Perfect for the marketing people to build on and why not? The reality may be quite different. Vergine or virgin olive oil only became important in 19th century. Before that all oil was vergine as there was no treatment for oils. It seems to me highly unlikely that it would be used to describe the obvious. "Untouched" oil has no significance if all oil is untouched. The 19th century saw the development of chemistry particularly organic chemistry and an understanding of acidity in olive oil that could be changed by treatment. In the modern age when we are reinventing our romantic and mythological past we forget that this age of scientific optimism and progress continued from the 19th century into the 2nd half of the 20th. The use of the word "refined" indicates that people thought it was better than the original vergine. This is confirmed by an early Italian food writer at the end of the 19th century who said that the olive oils from Perugia were not much good and they needed a factory to refine them!! These virgins must have had a busy time. No off season holidays. When they were not pressing olives they were lending their name to the virgin lands of America and Russia as well as virgin forests in Brazil and heaps of other places. As far as the origins of the olive are concerned we will probably never know but there are good guesses and bad ones. The bad ones are areas which are too cold for modern olive trees to grow in. Agricultural crops have changed enormously over the last 10,000 years due to human selection but I cannot see any logic in selecting frost resistance out of olives. If olives come from some of the freezing places suggested there should still be some of these super frost resistant ones left there. Cheers Brian Chatterton. </pre> </td></tr></table> |

<pre>Regarding olives in cold areas - check with Professor Andrea Fabbri at the University of Parma.I visited some trial sites where he is growing a number of selections as well as regular varieties. On another note - the best climate for growing oil olives is one where ¥ chill factor is met ¥ No frost ¥ Rainfall + Irrigation = 800-1000mm rainfall ( winter rain effective over hot periods) ¥ Plenty of solar radiation ¥ Plenty of heat degree days ¥ No fog/low humidity especially over hot periods Outside of this growing becomes more marginal = greater effort and cost - Low Crop Yields - Higher levels of irrigation - More chemicals required etc etc Stan Kailis </pre> </td></tr></table> |
