Aromatic Materials ** Was: Infused Oils (David's not Crazy!)

[Guest guest]

Hey David .. and Dennis .. and other good folks ..

Welcome you are. And I never figured you were crazy. :-P

Florentine Flask you mean? There are some photos about 2/3 down the

page at URL http://www.av-at.com/distillation/rosadamascena2.html

True it is .. and later they filter the Hydrosol too .. removes tiny

bits of aromatic materials .. which DO make it through the system.

 

But .. I was replying to what I read .. which was obviously not what you

meant. I read the below ..

And it seemed to me you had substituted eo for aromatic material cause

(1) we do dry most aromatic materials for reasons I stated and (2) we

ain't yet figured out how to get the moisture out of no danged EO. ;-p

True .. the filters absorb water and strain any microscopic bits of

plant material. And .. those microscopic bits can cause Hydrosols to go

bad too .. with some exceptions .. like Oregano.

Roman Chamomile (Anthemis nobilis) is easily good for a couple of years

if stored properly .. but German Chamomile (Matricaria chamomilla) can

begin to lose its color and odor in a little as six months if improperly

stored. It'll start to turn from blue to green as the chamazulene

oxidizes. With oxidation we have deterioration of the essential oil.

That's fine but maybe not really necessary till you have time .. cause

now we are on the same sheet of music. Twas just a matter of me reading

what was written and responding accordingly. ;-)

Yessir .. and you.

But .. I don't think the Aussie terms will catch on here .. the Turks

say they filtre (as in Fill Tray) the oil. ;-p

 

Another thing that has given some folks false expectations .. from some

of the many novels out and about on Hydrosols. Hydrosols DO contain

bits of aromatic materials .. strain them all you want but they will be

there. We filter hydrosols daily .. keep a big filter going. And when

a barrel sits for a while it will have lots in it.

 

Couple of years ago I had a buncha 50 kilogram barrels of Rose Hydrosol

delivered to my office and it was straight from the still .. plus it had

been filtered. The delivery service had knicked one of the barrels and

I was afraid it might puncture due to pressure in flight from Turkey to

the USA so I decided to pour it into a new barrel. Two of us began to

pour into the new barrel and toward the bottom of the old barrel the

Hydrosol began to run with a much deeper color of red. Normal it was.
