None of the above is the short answer but maybe some of them. Below is a
short summary of the debate so far. There seems to be no clear answer as to
the variety(ies) currently planted in Oz. As you will note from a perusal
of the summary it seems that M. Prieta is the olive for oil and M. de
Servilla(Sevilla) is renowned for a table olive. None of the cv's you have
mentioned have yet had a mention. Of course it is known that many cultivars
have many different names and some confusion therefore arises. Considerable
confusion.
There is a stack of other material in the archival section. If you can help
clarify the situation it would be appreciated by many a grower. As I have
stated before my Manzanillas have been yielding a consistent 16%+ wxw. They
are an unknown cv of M that are about 35 years old sourced from a particular
area of Oz. The mother trees are being DNA tested and results are still
awaited.

It will appear very soon in the journal Euphitica the analysis of 56
olive-tree cultivars in Malaga (Spain) that correspond to 22
different varieties using molecular markers based in DNA.
Among the varieties we have differentiated, you can find Manzanilla
sevillana (which is usually called outside Spain 'Manzanillo'),
Aloreņa (that is also called manzanillo), morisco (also called
manzanilla prieta), and zorzaleņo (also called manzanillo).
You can see the nightmare. All these but morisco are use for table
olives, although you can obtain some oil, although the productivity
is lower than other varieties.
We have seen that olive-tree varieties used for table olives use to
cluster in a dendrogram, but we have not determined wich genes are
involved in this characteristic.

FROM J ARCHER, OLIVES AUSTRALIA
We did some laboratory oil tests on our Manzanillo mother trees in the same
season (harvested March 24th, 1999) and found them to be 17.9%. This is
less than the recognised average of 20.3% as published in the University of
California Olive Production Manual. However in the same publication
Sibbett, Connell, Luh and Ferguson list Manzanillo's oil content as ranging
from 15% to 26%. We feel that the 17.9% result may have again been due to
the wet season experienced. (NB. All laboratory oil percentages listed were
obtained using the internationally accepted Soxhlet extraction and
standardised to 50% moisture content. Whole fruit were used for the
testing.)
To continue our research, this last season (2000) we again did some
laboratory tests on Manzanillo fruit from our mother trees. The 2000 season
had been relatively normal as far as rainfall and irrigation are concerned.
The laboratory oil content result 22.9%.
We also did some pre- and post-processing laboratory oil tests this season.
One Manzanillo sample, for mostly coloured but not all black fruit, resulted
in 22.9% oil and another from a later harvest resulted in 23.7%.
Manzanillos from a different section of the mother plot gave 20.4% oil. Our
machine operator, Tony Duffy put a batch of the 20.4% fruit through the
Oliomio and extracted 12% oil. We then sent the waste paste from that batch
to the laboratory and they extracted a further 8% oil, giving a total of
around 20%. Naturally, we are researching to learn how to extract more of
the oil from the fruit.
I have no question that the trees which you understood to be Manzanillo from
our recent correspondence are in fact the true 'Manzanilla de Sevilla' of
Andalucia, Spain. The difficulty is that in some regions of Australia and/or
seasons, the high moisture content is holding onto the oil and not letting a
portion of it be released.

FROM PROF FABBRI
Manzanillo is among the best table cvs in the world, but is not to be
chosen for oil. But 0.1% is really too small a figure to blame the cultivar.

>which type of Manzanilla were planted in Australia?
I wonder if you know that the name "manzanillo" is used for a lot of
different varieties.... Most of cases it refers to the tree that
Antonio GIanno cited, but you have a lot of other olives that are
also called manzanillo or manzanilla that are used for table olive
oil.

It should be... (both means the same, as if you say Sevilla's
Manzanillo or Manzanillo of Sevilla)
But I would not bet my neck. :-)

FROM IAN AND JENNY FRASER
3. We can say again that our M's were ripe when picked, as confirmed by Mr
Caird. Fine handsome fruit from trees planted 8/96. We irrigated three
times, all pre-Christmas, but it was a wetter summer than usual. This might
make for a lower yield but surely not an awful one, and we hear tell of
people with lousy Manzanillo yields from all over the place, far apart from
one another.
4. Another question that keeps coming up is that of Manzanillo
sub-cultivars. We believe that many of us sourced M's from the same
nursery, but what about M's which have come from different suppliers? How
are they yielding? Can any O/Line experts/readers/lurkers comment on this?
Do we in fact have two or more M sub-cv's in Australia performing quite
differently?
5. Mohamed, we do feel it proper to take experts' opinions very seriously
(those of Prof Fabbri, Gonzalo and others). Not for one second do we
believe that Prof Fabbri is saying you can't get oil from Manzanillos.
Fabbri's point, we feel, is that the M is above all a pickling variety, and
that's why you should plant it - for pickling. When you choose cultivars at
the time you set up, why not get it right at the very start? And getting it
right, naturally, depends on the best advice.
6. It should also be noted that some growers here express genuine doubts
about the quality, flavour, organoleptic and keeping properties of
Manzanillo oil (ours tastes pretty bland). An oil producer we met yesterday
remarked that he finds M oil doesn't keep terribly long and lacks character
on the palate.
