the “maraschino” blackberry illusion

Filed under: distillation — Tags: , , , — sjs @ 2:10 pm

the maraschino cherry is an interesting art object.  to many its just a preserved cherry.  but it also can be a trick of expectation and anticipation.  you expect this simple looking preserved cherry to taste like a cherry and it does… but also with the intense almond-y note of the pit.  this was done by an alcoholic solvent bringing the character of the pit to equilibrium with the rest of the cherry.  but you can’t just use any alcoholic solvent.  because we are dealing with equilibriums and certain expectations that must be met, the solvent has to have the same aroma as the juice of the cherry… therefore it must be a cherry eau-de-vie.  that is usually the first mistake people make in making “brandied” cherries.  if you use something with different aroma than the fruit, equilibrium will strip the flavor out of the fruit with often horrific consequences.

well maybe we could do this with another fruit than cherry.  but none really have a pit or inhomogeneous element that a solvent could homogenize.  so what we would have to do is aromatize a fruit brandy with a spice and push it into a fruit instead of pulling it somewhat out. hence we have the “maraschino” blackberry. blackberries soaked in blackberry eau-de-vie that was distilled with mace and grains of paradise (then mixed with vitamin C powder as an anti-oxidant).

well i more or less executed the “maraschino” blackberry idea but came to a stumbling block.  i made a nice blackberry eau-de-vie that i distilled with an “inuitive” amount of spice (i didn’t measure).  the resultant elixir was definitely palatable on its own and not over intense in spice by itself.  things got messy after i added the black berries and let thing sit for a couple weeks.  you can drink the liquid on its own, but the spice aroma in the black berry upon eating seem wretchedly over extracted.  you have to spit it out.  there is obviously some trick of perception that amplifies certain sensations, but how the hell does is it work?

i think i will just dilute the spice extract with more plain eau-de-vie and see what happens.  the “maraschino” blackberry may still be salvaged, but i need a better understanding of this flavor illusion.  i’m reminded of two experiences.  years ago i made a simple clove infused whiskey with seagram’s vo and probably ten cloves per liter.  the infusion tasted really flat and un-clove-like until you added some triple-sec.  wow did the flavor wake up.  sugar is a known flavor enhancer and likely its full potential was unleashed on the cloves.  the same could be happening to the spices from the sugar in the blackberries.  but there isn’t much sugar in the blackberries (maybe just a few %) and much of that sugar was brought to equilibrium with the rest of the liquid.

another experience was drawn from making a simple pineapple rum infusion.  when it comes to equilibrium and you eat a peice of pineapple you get a sensation that you’ve just taken in over proof rum.  even to someone quite desensitized, the sensation is a jolt.  it doesn’t seem probable that the pineapple has more alcohol than the liquid.  so what gives?  is it a result of the texture?  maybe.  blackberries and raspberries taste great whole but when you juice them and rob their texture they taste flat and muted.  to get any life back into them you need to abstract and ameliorate them with more sugar and more acid.

maybe we are experiencing an abstraction through texture.  all those tiny blackberry cells keep popping in your mouth hitting you with barrage after barrage of sensation.  it echoes and amplifies…  i know ferran adria experimented with “limes with texture” where he overshadowed the character of cucumber with lime to borrow their texture.  i wonder if anything was amplified and maybe he was inspired by other fruit abstractions that we more commonly encounter.

potential amusement abounds…

deconstructing campari

Filed under: distillation — Tags: , — sjs @ 3:07 pm

so i thought i knew a lot about all things alcoholic but i keep finding lots of holes in my knowledge. one to clear up is whether amaros like campari are infused then redistilled or not. do they simply infuse and filter then color? sounds more practical. distilling has huge energy costs and sometimes it seems to over engineer the results. and are any bitter principles volatile enough to come through in a distillate? does the results either way have any implications for an understanding of absinthe containing wormwood which is the most bitter substance i’ve ever come across?

so for the expiriment i took 500ml of campari and added 500ml of water then distilled out 500ml. using a nice amount of reflux campari’s small amount of alcohol came out quickly then i was mainly distilling water to make up the volume.

now i have two 500ml volumes. one is clear, has the 24% alcohol, and whatever aromatic principles came through. it smells just like campari but is barely bitter or maybe just has the taste that my brain associates with bitter things. now the second volume is slightly darker red than the campari (maybe because i caramelized the sugars?) and does not smell campari-esque at all. it actually smells slightly like juniper but who knows if that is from residues in my still or from the containers i’m reusing. the second volume definitely has a lot of bitter to it but less than campari. (or maybe not when i sit down and drink the real stuff…)

so the results here are really similar to my distilling of a quinine tincture. no bitter in the distillate. now i have to try it with wormwood and see how the results come out. if the results were not bitter absinthes could have had lots of wormwood in them. my previous understanding was that you could never put so much wormwood in because no one would be able to palate the stuff…

one more thing that i can derive from the campari experiment is how much sugar is in the product. now that i have a volume with no alcohol i can use either a refractometer or more accurately a hydrometer to gauge how much sugar they add. (i just ordered some specialized hydrometers… can’t wait to try them out!)

***update***

so i finally tried out my specialized hydrometers. campari lied just between the end of one and beginning of another so my very good estimate is there is 22 brix to campari. now i could take this farther and see how much the alchol obscures the measure of the campari’s sugar content using the same hydrometer on the real stuff.

hypothetically speaking…

Filed under: distillation — Tags: — sjs @ 4:10 pm

hypothetically if you could operate a still what would you put through it? were you ever interested in learning anything about distillation through maybe some sample distillations?

so what distills?

solids don’t… colored stuff doesn’t but sometimes you get a louche…

does acidity distill? do spirits have an acidity that we should be paying attention to? how does distilled vinegar work?

what happens when you distill a vermouth? does it turn into what we would call a gin? how many grams of botanicals per liter are in a typical gin… what else would taste good in a gin? can you re-concentrate the botanical strength and alcohol of gins?

how does framboise eaux-de-vie differ from pears? does one have fermented fruit and the other simply have macerated distilled fruit?

what else would you want to know about the distilled things you drink?

***update!***

so i redistilled my african rye whiskey infusion. all of the rooisbos flavor was really in the tales of the distillation. the previously aged overholt rye whiskey is now clear again and some of the barrique flavor seems to be left behind… the stuff left in the still after the alcohol and volatiles were stripped was darkly colored and barely flavored. i would love to learn more about the short term maturing of distilled spirits because it seems to taste radically different 24 hours later. its less harsh like the water is more integrated and you can perceive more of the rooibos identity.

***update!***

so i had a pound of quinine powder that was sitting in a couple liters of cognac. i let it sit for a couple weeks or so and racked it off to make a quinine tincture via infusion. its gorgeous… ebony colored, aromatic, sickeningly bitter… what more could you want… well the solids saturated with probably a liter left of the cognac sat for many months in a 3 liter mason jar. i just decided to redistill it. what i was wondering was if my distillate would taste bitter? i distilled it at a very high reflux rate until i was sure i was into the tails but the product never became massively bitter. i didn’t bring it up to 212F but i expected to get a lot of flavor without having to. it is very aromatic and flavorful like you would expect quinine to be but not bitter at all…

if i redistill campari what will i get?
