Fwd: Gin - Vapour extraction Quantities
- Bombay Sapphire Gin uses a Carterhead Still, which is a type of reflux
column - the vapor from this then goes into a tank (gin head) that
resembles a 'doubler' on a moonshine pot still. This tank contains
botanicals on a sieve type tray. The flavor of the gin is apparently
more subtle than other gins using soaking (24 hrs) and then
redistilling. Some Dutch companies use several redistillations using
different botanicals each time as different botanicals release their
oils at different times.
Their recipes are now formulated on the basis of essential oil content
as botanicals vary in this depending on geography and climatic
That's all I have picked up in the literature around.

Yes I agree that the taste is probably quite subjective, you either
or you don't, and you can't please everyone. Also the freshness of the
botanicals would be an issue.
I was going to 'redistill' a wash of ethanol @ 96.6%abv diluted with
filtered water down to say 45% abv. The temperature changes will
still be a
problem as the ethanol/water mix changes, but perhaps I can take cuts
the output and compare later.
I'll give it a go using the infusion mixture from the Archives Msg
Quantities intrigue me also.
Your message 2132 is the most authoratative on botanical
which would be 2 parts juniper, 1 part coriander, 1/4 part
bark and angelica root, and 1/40 part for the other
Multiply by 10g to get quantity to flavor 1 litre of alcohol
as it appears about 40g of botanicals is sufficient. i.e. you
macerate the 40g of botanicals in 1 litre alcohol 45%abv, and
redistill. Dilute to 45%abv again. 45%abv appears ideal to
volatile essential oils.
So for steeping in 4 litres of 45% abv I would use:
80g Juniper berries, bruised
40g Coriander seeds
5g Cassia bark
5g Angelica Root
1g Lemon peel
I wonder if Waljaco or anyone else would care to comment on the
required for suspending the botanicals in the column and just heating
litres of 45%abv in the boiler? Since the botanicals are not steeped
subjected to heat and water/ethanol vapour would the quantities need
considerably larger, or are the majority of volatiles extracted quite
quickly and early on? Also, as the re-distillation progresses, the
proportion of ethanol in the vapour would start of rich and descend
lean, extracting, I suppose a different range of volatiles from the

The quest seems to be for the ultimate Gin.

I can't source fresh Juniper berries... so I'll take what I can get.
Next...Cardamom pods.... how stale are they??????
Coriander seed or roots....what's the use by date??????
Orris root ....has been sitting in some hippie crafties draw to make
pouri smell nice for a long time. OK ...add this all together and
a comparative Gin to the commercial brews. Oh dear... I think not.
The "hang 'em in the tower" approach was so disappointing. As the
distillation temp changed ..so did the Gin taste. I think the same may
true of a GIN HEAD still in small quantities. We're trying, on a small
to outdo a commercial business.... So therefore, I took a leaf out of
old farts' book.....make the best ethanol that you can...and then make
flavouring to suit what you want to drink..easy peasy!
I'd love to make a gin head still, but unless I wan't to make
Coriander Flavoured Schnapps....(NOT)...that's a lot of equipment
the one direction!!
I now have 6 or 7 flavouring stills ......to let flavouring fantasy
where it may...and then try and make large quantities of the purest
that I can....add a flavouring....gives me a chance to get it
Sorry, I'm raving on a bit, but I think the closest taste is still
alcohol...followed up (or mixed) with the best essence you can
that's fun. Gilbeys Etc., have been selling us bad grog for
make purer grog...lets flavour it commensurately or better.
Sorry for the big rave.. ( and didn't you like the quote ..."to let
flavouring fantasy fly where it may") God..couldn't a bloke get hung
