Hej alla
Bifogar lite läsning om sockerkulör i whisky klippta från
http://mailhost-alt.rz.uni-karlsruhe.de/warc/malts-l.html "I've checked out and discovered that spirit caramel is E150a, not E150b as
I'd previously assumed.
The four grades of caramel are:
E150a Caustic (spirit) caramel aka plain caramel: excellent stability in
alcohol - designed for high-proof spirits. Prepared by controlled heating
of carbohydrates with/without alkali or acid.
E150b Caustic sulfite caramel: high stability in the presence of alcohols
and tannins. Intended for use in aperitifs and alcoholic beverages
containing plant extracts. Prepared by controlled heating of carbohydrates
with sulfite-containing compounds.
E150c Plain ammonia (positive) caramel aka beer caramel: designed for use
in media where +charged particles from other ingredients are present.
Prepared by controlled heating of carbohydrates with ammonia.
E150d Ammonium sulfite (negative) caramel aka soft-drink caramel: designed
for use in media where -charged particles from other ingredients are
present. Prepared by controlled heating of carbohydrates with ammonium and
sulfite-containing compounds.

And this is a quote from the Cerestar site ´FLAVOUR: When diluted for use,
caramel colour has a distinctive, pleasant taste which can contribute to
product flavour.´

"There are different types of E150. Allegedly this was the kind that gives
maximum colour with as little taste as possible. (The person I spoke to
couldn't say whether it could be classified as the E150b variety.)
I got the stuff this summer and had planned to try it in an uncoloured
lowland whisky. But unfortunately, the only whisky I had that would qualify
was Cadenhead's 1981 Rosebank and I just couldn't make myself taint it with
it. Then I forgot all about it for a while.
Yesterday I finally carried out some preliminary tests. I had decided to try
it in Absolut Vodka, which I had at home. In order to be able to administer
the extremely minute quantities that would be required to colour 3 cl vodka,
I took a sewing needle and put the sharp end in a cork. Then I dipped the
eye of the needle in the caramel and wiped it off a little. This proved to
be a very effective way of colouring and I could exactly control the tint.
Unfortunately I have no idea how much E150 I used. I think the chemists on
this list have much better equipment for this.
I started out by nosing the E150 bottle. The smell reminded me of soy sauce
a bit, but when I smelled real soy sauce I discovered that my memory had
played me a little trick. It was different but a little bit similar in a
way. It had a burnt (bitter) and little sweet character (surprise,
surprise). Not exactly pleasant. It was also very viscous.
I took two nosing glasses and poured 3 cl vodka in each. Then I tinted one
glass to a colour similar to Cadenhead's 1981 Rosebank (46% abv), or to
Douglas Laing's 1981 Brora for that matter. (Or to be honest--my memory of
them--light yellow anyway.)
When I nosed the glasses (eyes open) I wasn't sure if I could perceive any
difference. Or maybe I could, but it was just at the subliminal detection
threshold. When I tasted the stuff I could detect a weak note of burnt
sweetness. More bitterness than sweetness I thought, but it gave the taste a
little rounder and fuller character. When I increased the amount to give the
vodka a colour that more resembled Laphroaig 10 (40% abv), it became more
obvious. What really struck me was that the vodka acquired a rounder and
fuller character. I can really see why the whisky industry likes this stuff
so much.
I ended the tasting session by trying a spoonful of undiluted caramel. Yuck!
I spat immediately, but it was difficult to get rid of the cloying feeling.
My teeth turned yellow and I feared I would have to talk like a
ventriloquist at work the next day. Luckily it all went away when I brushed
my teeth and I didn't have to gargle with chlorine either.

Cheers for now

"Craig mentioned off-list to me about watching an industry demo of spirit
caramel being added to water, and that set me thinking. Why don't I just go
and buy some of the stuff and see if I can detect its flavour in an ethanol
solution. So today I visited Moonshine Supplies in Taupo (the small town
near where I work) and bought some distillers' caramel. I cannot claim this
is what the Scotch industry uses because even after ringing up the
importers, I was able to confirm only that it was E150 (ie caramel), but
not the specific E150b (spirit caramel) that is legal for addition to
Scotch whisky. Also it contained agen E477 which is definitely illegal as
far as Scotch is concerned. The importer assured me that E477 is
flavourless, but that's what the industry tells about E150b right?
So, in tonight's experiments I discovered that it takes 4ml of caramel to
turn 700ml of water into a colour exactly (eyeball exactly that is)
matching the Special Distillery Bottling Glentauchers, which is on the dark
side of amber, and surely has to be caramel-coloured as it is exactly
(eyeballs again) the same colour as the Special Distillery Bottling
Miltonduff - too much of a coincidence for me to believe they both were
naturally identical.
Next I made up some 40% abv ethanol solution and coloured that up to match.
Admittedly this would require more caramel than a whisky from cask which
would have significant natural colour. In solo blind tasting I discovered
that I could not tell the difference (by nosing, Åkes anmärkning) between blank ethanol and coloured,
but could detect a flavour difference (surprise, surprise - the coloured
stuff had a vaguely toffee taste). The lack of nose difference I put down
to the lack of volatility of the caramel.
Hardly a definitive test, but it supported my prejudiced view that caramel
colouring can impact on whisky flavour.
And I know I'm right because I'm irrefragible.

"Caramels for use in the drinks industry are produced through controlled
heating of a mixture of simple carbohydrates and food-grade alkali or acids.
What goes into Scotch whisky is formally known as "E150a" and colloquially
as "Spirit Caramel" or "caustic caramel." It is made by heating sugars
(typically a glucose syrup) with sodium or potassium hydroxides until the
appropriate amount of Maillard and other breakdown products are produced
(for spirit caramel this is deemed to be when a color of between 17000 and
25000 EBC units is reached).

Tyvärr är smaksinnet (eller egentligen mest luktsinnet) inte så objektivt och välstrukturerat utan även bl a utseendet på det vi äter och dricker påverkar vår smak-/luktupplevelse. Att färga whisky är alltså att lura konsumenten.
