  • Eyeballs Inside Ice Balls – Halloween Ice

    I did another stupid thing! 

    I bought some bouncy eyeballs in the Halloween section of the drug store and put them inside the IceOlogy clear ice ball maker.

    The balls float inside the ice ball molds so when they freeze they're touching the outside of the ice ball- I'd prefer them to be fully enclosed in ice. Because the balls are not food safe I would not recommend serving these to customers in a bar setting, and because they touch the outside of the ice I'd not recommend serving them in alcohol, lest it degrade the plastic.

  • Ramping up Aromatics in Cognac: How Camus Does it

    When I was in China helping judge the Camus cognac Shanghai Shake, I had the opportunity to interview president Cyril Camus. 

    Recently the language on Camus' core line changed to invoke "intensely aromatic" language on the branding. Cyril says that this has rolled out in the US and some other markets, with more to come. They're particularly promoting the VSOP (using the phrase "Very Special" instead of VS on that marque).

    SONG4598_w3207

     

    I asked Cyril about the reason for the rebrand/change in flavor profile- particularly from a marketing perspective. What was the consumer demand for the change, if any? Was it to be more useful in cocktails? 

    He says that this was not the case. "I think that the density of aromas and lower level of wood allows you to make more aroma-forward cocktails. It's good timing, but wasn't the reason we did it." 

    SONG4956

     

    In the first place, I didn't realize that this flavor profile change wasn't instant; it's more of an evolution of flavor profile building up to the VSOP/XO of today. Cyril says about 15 or 16 years ago, they were trying to define from a consumer standpoint how people define or judge a cognac as the best. They wanted to have a "measureable, distinctive point" of quality over other brands so that they didn't need to rely on the typical language of 'a blend over over X cognacs aged up to Y years' that all the other brands use. 

    They determined three important factors: the density of floral aromas (which they measure via concentration of terpenols); density of fruity aromas (measured in count of esters); and the balance between fruit notes and wood impact. With this in mind, they set out to move the flavor profile towards something "obviously distinctive."

    The biggest change made (about ten years or so ago) was distilling on the lees – the dead yeast and other particles from the winemaking process left unfiltered. According to their materials, this raises the amount of esters from 30mg/L up to 70 mg/L. 

    One thing that hasn't changed is Camus' use of grapes from the Borderies region, where Camus is based. Cognac from this region is said to be more floral than from other regions, and this adds to the terpenol count. The Borderies is only about 5% of the total cru for growing cognac grapes.

    In the vineyard, they make efforts to have the best wine by putting weather stations in the vineyards (only about 10-15% of the grapes they use are from their own property) to know best when to harvest, and then harvesting extra-quickly with larger machines than are strictly necessary. As grapes are being transported to the presses they are seeded with yeast, which I'm guessing is to ensure any natural fermentation that happens along the way happens with their own yeast strains rather than the natural ones from the vineyards. 

    Camus distills about 90% of the wine sourced from about 200 growers (plus their own grapes), and the rest is distilled according to their patented process. 

    About that: another factor in ramping up aromatic intensity is including more of the heads of distillation in the product. Cyril says that the first 20L of the second distillation are the heads are removed and stored separately liter by liter. Cyril says that though the heads are known for being very aromatic and full of esters, they're also pretty unpredictable in quality. So the master distiller will go through and taste/nose the heads and include back into the heart the desired heads fragments. These heads are not aged separately but put into barrel with the hearts.

    This brings up the esters from 30mg/L without lees to 70 with lees to 200 mg/L with their "intensity distillation" process.

    I asked Cyril if since they were making these adjustments gradually if the XO (a minimum of 10 years old) was of the same level of aromatic intensity as they were seeking to achieve with the VSOP. He said that distilling on the lees, which they've been doing for 10 years now, has the majority of the impact, and though the flavor profile will change a bit in the future years, those changes will be minor overall. But, he says, they're now in the position to explain to consumers why they're different. 

    As for the balance of fruit to wood notes, they're also using fine grain oak for their barrels low in tannins and lightly toasted to minimize the wood impact on the spirit. They also use older barrels that have had many of their tannins stripped already.

    It's terrific to see some numbers and logic behind what a cognac brand is doing!

     

  • Dinosaur Head Ice Block

    I was recently in Shanghai judging a cocktail competition and saw a dinosaur hand puppet for kids in a store. Naturally, I thought, "I bet this would fit in my cooler and make an awesome ice block."

    Ice fans, I was correct. 

    Dinosaur mask ice block2

    The head fit perfectly into my igloo cooler. I filled it with water along with the cooler and stuck it near the water's surface. It was just touching the sides so I didn't need to support it- perfect fit. 

    If you're not up to speed on how the block came out so clear, it is because of Directional Freezing. I didn't allow the entire cooler to freeze, but removed it before the whole block froze; about 2 days. (In fact the bottom side of the dinosaur isn't frozen enough and pokes out of the ice a bit – if I do it again I will leave it in a little longer.)

    This would be a fun presentation as a display block for events.

    Even better, if I made yellow-tinted ice balls (saffron-infused water) and put mosquitos inside them, for a full Jurassic Park themed cocktail service!

  • Testing Out IceOlogy Clear Ice Cube Trays

    I was recently contacted by Dexas, a company that makes ice*ology ice cube trays, to give them a trial run. 

    81jQvJG0sTL._SL1500_
    81jQvJG0sTL._SL1500_

    The company makes three versions:

    The cubes are about 1.75 inches on each side, I believe the spheres are also 1.75" diameter. 

    They cost $40 for 2 cube/sphere trays and $50 for the 8 cube trays

    I tried them out twice, and they're good. Like all clear ice cube trays, they take advantage of directional freezing, the process I uncovered nearly 10 years ago on Alcademics. 

    Like most clear ice trays, they employ an insulated container, a big tray that holds a water reservoir, and a smaller tray in the shape of the desired ice cubes.

    The main difference between these trays and others is that the cube/sphere trays separate sideways, which makes them easier to remove from the silicone container than others that must be pried apart. 

    They recommend that the reservoir trays be microwaved to release the cloudy part of the water so that they can be reused quickly for the next batch. I didn't try that but just ran hot water over them and this was effective, but I appreciate the easy turn-around time.

    Pros: 

    • easy to use
    • easy to remove cubes/spheres from trays
    • make very good clear and solid shaped ice
    • seem sturdy and long-lasting after a few trials

    Cons:

    • a bit small – 2" cubes would be better
    • a bit pricey at $40 per two-cube tray
    • 2 cubes at a time isn't many 

     

     

  • The Life and Death of Kold-Draft

    Over at Punch, Drew Lazor wrote a story about the Kold-Draft ice machine. He covers the role the big clear ice cube maker played in the cocktail renaissance (I didn't realize it was around so long), and how many bars are abandoning the machine today due to its problematic performance record. 

    Lazor quotes me in the story:

    “I used to say at the time that the Venn diagram of America’s best cocktail bars and bars that owned Kold-Draft machines was a near-perfect circle,” recalls drinks journalist and ice enthusiast Camper English.

  • Cocktail Coloring – Natural Food Colorings to Use in Drinks

    Below is a list of colorings that can be used to turn your cocktails  blue, green, red, yellow, black, white, etc. and include everything from dragon fruit to squid ink. 

    I've made tasting notes when I've tried the colorings, and sometimes added some commentary about the colors. The links are to purchase items from Amazon. 

     

    Blue and Purple

    • 916CFBVuqdL._SL1500_Purple Corn [buy]  no flavor when added to liquor/water. Boiled purple corn produces tons of deep purple color and has a slight corn husk note. 
    • Butterfly Pea Flower [tea bags] [flowers] [powder form] – This flower starts off bright blue in neutral water/alcohol/syrup. It changes to purplish to pink when something acidic is added, like most cocktail ingredients. It tastes only slightly tannic with a subtle wilted vegetation note. 
    • 913NZ+Mh2ZL._SX522_Blueberries [freeze dried] – These turn from light blue to pink. They have a vegetal grassy note; slightly perfumy. Not enjoyable as a flavor. Perhaps fresh is best. 
    • Blackberries – Produce good purple color. Taste (frozen blackberries) weedy, earthy; fresh grass notes. 
    • Blue Spirulina Powder [buy] Brilliant color! There is a slight seaweed nose but not much flavor at all, so this is good for coloring. With added acids like citrus juice, it changes to a turquoise blue.  See the picture below. 
    • Acai Powder [link
    • Ebony Carrot Supercolor Powder [link]

     

     

    Red and Pink 

    • 81WWupJAPfL._AC_UL320_Raspberries [freeze dried] – These don't release as much color as one might suspect. The taste is super bright citric sharpness. These would probably add citric acid taste to beverages. 
    • Hibiscus [dried] -  Produce an intense color with a small amount; purplish red. They have a sharp dried leaf note. 
    • Strawberries [freeze dried] – Because the red color is just on the outside, strawberries tend to give off only a slight gentle pink color. Freeze dried strawberries seem to give more color than frozen/fresh. 
    • Beets [beet powder] – Fresh beets give bright color; dried more often a dried blood color. The taste of beet powder can be cardboard-meets-super dry earth/dirt, so best to minimize the amount used. 
    • 91wVBs-4RxL._SL1500_Cranberry – Does not release much color. Not recommended. 
    • Dragon Fruit Powder [buy] – I have not tried this but it was recommended to me by someone who has. I believe this is was Starbucks and other brands use to make "unicorn foods." 
    • Cochineal – This dried insect makes a red to purple color range and is used in some liqueurs including Bruto Americano. It is available for purchase but please ensure you buy a version approved for food use. By default it will be intended for use on fabrics. 

     

    Yellow and Orange

    • 91FUxZ1XMiL._SL1500_Annatto [buy] – These can be either red seeds or ground to yellow in color to start with, and can produce a bright orange color. The flavor has touch of anise and dry carrot peel, very much in the range of cocktail flavors. 
    • Turmeric [buy] – Deep mustard yellow color. Taste is bright yet grounded earthy; will provide base notes in drinks. 
    • Saffron [buy] – Gorgeous golden honey yellow color with only 1-2 threads. Not much flavor; grassy like sucking on a flower petal; slightly woody. 
    • Mustard Seed/powder – Most is a mellow yellow color. 
    • Orange Carrot Supercolor Powder [buy]
    • Paprika – Doesn't seem very effective as a colorant but has strong flavor.  

     

    Green

    • 61wmdwqda3L._SX522_Matcha tea [buy powder] – The kind I tried was a tea with jasmine. It had a swampy tannic bad flavor. Probably other brands taste better. (The linked powder is not the brand I purchased.)
    • Green Spirulina Powder [buy] – Unfortunate "low tide" smell; seaweed to fishy. However the taste comes through only slightly and is probably hideable beneath other ingredients. 
    • Fresh green herbs and plants, muddled to order – anything with chlorophyll
    • Wheatgrass powder [buy]
    • Pandan Leaf Powder [buy]

     

    Black

    • 813hGZPPLbL._SL1500_Activated Charcoal (not recommended) – Note that activated charcoal can disable medications if taken within a few hours. I don't recommend using it on cocktail menus. This is not an approved food coloring in the United States. More information here
    • Carbon Black – This is an approved food color in the EU and Canada, but not in the United States. 
    • Food Coloring [link]
    • Black Sesame Seeds [link] – These can make cocktails look greyish to blackish. 
    • Squid or Cuttlefish ink [powder] [jar] – Available powdered or in liquid form. This is a commonly used food coloring though not vegetarian-friendly. 
    • Black Currants – Have a very dark red/black color. 

     

    White

    • Milk
    • Blanche Absinthe 
    • Cloudy Ice 
    • Anything that louches

  • Purple Food Colorings: Anthocyanin

    Purple cornAnthocyanins are pigments that, depending on their pH, may appear red, purple, blue or black. Food plants rich in anthocyanins include the blueberry, raspberry, black rice, and black soybean, among many others that are red, blue, purple, or black. [wikipedia]

    That purple color-changing butterfly pea flower tea? [tea bags] [flowers] [powder form] Anthocyanin. The purple cabbage science experiment you did in middle school? Anthocyanin. 

    Wikipedia offers a list of food sources with high anthocyanin levels. I put them in descending order below. You might choose to use them to color your cocktails. 

    • Purple corn leaves
    • Purple corn [buy]
    • Dried red cabbage

  • Extracting Natural Color from Plants: The Freeze-Thaw Method

    In advance of my seminar at Tales of the Cocktail on Color in Cocktails and Spirits, I am putting up a few blog posts that the attendees (and you know, you) can use as reference. The images below are exported PowerPoint slides. 

    I was trying to create some natural colors from plants and read about how dyers do it. Many of them are not practical (or safe) for food and beverage use. Some ways to extract color that are safe include: 

    Slide123

     

    But one method I read about suggested freezing flower petals overnight, then thawing in hot water. This actually didn't work for me, but it gave me the idea for how to do it similarly. 

    The idea is that freezing plants breaks the cell structure and allows the natural colors to release when you add water. So what I did on my second attempt was to freeze the flower petals in water, then let it thaw out and strain out the solids. 

    This worked much better for me, and then I decided to repeat the process (not with new petals but just freezing and thawing the same ice cubes three times). Each time the color of the water became more intense. It worked! 

    Slide123

    With any flowers in particular or plants in general picked from nature (as opposed to the produce section), make sure that they're safe and edible. A great resource for that is CocktailSafe.org

    Slide123

    Above are the flower petals I harvested from my patio. I put them in 2' ice cube trays with some water. 

    Slide123As you can see, the colors came out lovely. 

    The idea is that you could now use this water as a base for a simple syrup, soda, or ice cube with the natural color in it. 

    Though I haven't experimented with other plants yet, I bet this technique would work great for many things. 

     

  • Aquafaba Future Experiments and Suggestions

    This week we've been learning about how to prepare aquafaba – chickpea or garbanzo bean water – to replace egg white as a frother in cocktails. The previous posts have been:

     

    712HMjfNlaL._SL1500_Along the way I've heard a few good ideas and suggestions that I have not yet tried. These all sound like great ideas and I love that they come from three different countries. 

    So far I haven't come up with a "best" way to make aquafaba, largely because I'm just trying small experiments at home rather than working in a bar with high volume. Hopefully these posts will inspire some folks to keep on trying and sharing their experiments too. 

     

    Frozen 'Faba

    Forest Collins of 52Martinis.com in Paris says, "I've recently tried freezing my chickpea water in 10ml batches and then pulling it out of the freezer when needed. It seemed to work well in the freezer, although I didn't do a comparison and only tried it in a blended pisco sour, but there was still a lot of froth on it." 

     

    Density Check for Consistency

    Daniel Seehuusen, Bar Manager at Avalon Hotel in Gothenburg, Sweden, says (edited for clarity): 

    I used to work with this a lot a while ago. Since we got our aquafaba from the kitchen it never was the same consistency.  So we used a oechsle meter, I think the sweet spot was around 35-37 OE (or was it 45….). [Note: an oechsle meter is analogous to a refractometer for measuring brix]

    I think that the most bang for the buck would be boiling the peas 2 times. Combine the liquids and dilute/reduce to the oechsle of your choice. We had it in a bottle, on ice. I think we used around 20 ml per cocktail.

     

    61Zzbmzh1+L._SL1000_Pressure Cooker

    Andrew Nicholls, co-founder of William George Rum from The Netherlands, says,  "I make an aquafaba by rehydrating chickpeas and placing one cup of the rehydrated chickpeas in a pressure cooker with three cups of water. Bring up to pressure and cook for 40 minutes.  The pressure helps “extract” more of the proteins/globulins, which makes for a more stable foam than canned chickpeas (in my opinion).
