  • Does Carbonated Water Make Clearer Ice than Still Water?

    This is another in my ongoing experiments to make clear ice. So far, I've tried comparing:

    Someone in the comments mentioned hearing that carbonated water would freeze more clearly than still water. As most of the cloudiness in ice appears to come from trapped oxygen, this didn't make sense to me, but I figured it couldn't hurt to try.

    I froze equal amounts of still water and carbonated water and this is how they came out:

    Tapvscarbonated

    The carbonated water is on the right, and it sure as heck isn't clear. It's got kind of a fun texture with lots of air bubbles in it, but that doesn't get us anywhere for the purposes of this experiment.

    Conclusion: Carbonated water does not make clearer ice than still water.

  • Nice Ice in the News

    The Associated Press released the following story on ice today, with a quote from your favorite icesperimentator Camper English. The whole story is here.

    SIP: Bartending trend calls for nice ice, baby


    SAN FRANCISCO (AP) — Erik Adkins spends a lot of time on ice.

    As general manager of the Heaven's Dog bar in San Francisco he's very particular about what ice goes into his cocktails, preferring hand-carved chunks for slow-sipping drinks and oversized clear cubes for lighter concoctions.

    And that's just the tip of the ice trend.

    Driven by the same quest for perfection that elevated bread, cheese and wine to objects of desire, ice has entered an epicurean age, coming in new shapes and sizes.

    Then I get the closing quote:

    On the other hand there's Camper English, a San Francisco-based writer and cocktail expert, who has blogged about his search for clarity, melting and refreezing ice at home to see if that decreases cloudiness and experimenting with distilled water.

    So far he hasn't been too successful, but that hasn't curbed his enthusiasm.

    "Ice is one of the fun projects that cocktail nerds can play with at home," he says.

    He'll go to some lengths for a chill thrill.

    "One time I caught myself asking a bartender to see their ice when I was making my drink order," he recalls, "because it was going to matter to me."

  • Does Hot Water Make Clearer Ice Than Cold?

    I have been doing experiments at home to try to get the clearest ice possible. So far my experiments have compared:

    I have not yet had success. Will the third time be the charm?

    (*Update – You might want to skip to this index page to see conclusions reached after many experiments.)

    This time I compared hot water to cold water to see which would freeze more clearly. The theory is that hot/boiled water has less trapped oxygen in it, and thus will freeze clearly because there will be less air bubbles.

    As I previously saw no significant difference in ice clarity between using tap vs. distilled water, I began with unfiltered tap water. One batch of water I left at room temperature. The other batch I boiled for several minutes. I put them in the freezer while the hot water was still hot. Here is what happened on three separate attempts:

    Hotvscold123

    The cold water actually looks a little more clear, but this could be because when the center of the hot water finally froze, it burst. I can't guess why this is because it's not like I have a super refrigerator that freezes ice in ten minutes.

    Another theory about why the first experiment failed is that as the hot water cools down in the freezer, it reabsorbs oxygen and acts just like cold water. To test this, I repeated the experiment, this time covering both plastic tubs with the lid before freezing.

     

    Coveredhotcold12

    Here the hot water ice looks slightly more clear than it did when it was uncovered. However, I'm not seeing a significant difference in hot vs. cold water, though the covered hot water may be just slightly clearer.

    Conclusion: Hot water does not freeze significantly clearer than cold water, even when the vessel is covered to reduce oxygen re-absorption. 

    In all of these ice experiments so far, the major cloudy factor in the ice has not been cloudiness throughout the ice, but a cloudy spot in the center of the ice. This spot is assumed to form due to the order in which ice freezes, from the outside-in. The oxygen migrates to the liquid part (in the middle) until it is the last part to freeze.  Kold-Draft ice machines produce wonderfully clear ice cubes in part because they freeze the ice in layers- water is sprayed in layers from the top down, so that oxygen is never trapped.

    Is there a way to freeze ice in a home freezer similar to a Kold Draft machine? Can we manipulate the way water freezes or change the shape of the container? Can we vibrate the container or stir the water so that the surface stays liquid and freezes last?

    We shall see, in future ice experiments.

    *Update – For a solution to the ice problem, see this post for a method that works. Also, an index of all of the ice experiments on Alcademics can be found here.

  • Drinks With: Francisco Alcaraz of Patron Tequila

    A few months back I had a very long lunch with Francisco Alcaraz, Paton Tequila's Master Distiller and Blender at the restaurant Kokkari in San Francisco. Alcaraz is not only the current master distiller, he created the recipe for Patron.

    Franciscoalcaraz

    Alcaraz studied chemical engineering at the University of Guadalajara then went to work as an inspector for an organization that was sort of a precursor to the CRT, the tequila regulatory commission. After that he went to work in a distillery and as a tequila consultant.

    Alcaraz developed the recipe for Patron at the distillery Siete Leguas (another brand still producing delicious tequila), where Patron was made from 1989 until 2002 before building their own distillery. Siete Leguas had both the traditional tahona (a giant grinding stone that crushes baked agave before fermentation and distillation) and a mechanical shredder (roller mill) that accomplishes the same thing, though these produce tequila with different flavors (and the topic incites long tequila nerd arguments). Patron uses a combination of tahona-crushed and shredded agave in its recipe.  

    Other differences from Siete Leguas' recipe include the type of yeast used and the source of the agave.

    The agave for Patron all comes from the Highlands of Jalisco, but it is not estate-grown. (That would be a darn big estate!) Alcaraz says they have contracts with seven large growers, and they do buy other agave on the open market. Another brand told me that they were required to buy some agave from small producers, but Alcaraz says that there is no requirement. There is, however, an incentive: The government (not sure if local or state) subsidizes part of the price of the agave to support these smaller farms. 

    Furthermore, Patron has long-term contracts with their growers to ensure that they will not be susceptible to the frequent agave market shortages that take place in cycles. (Another way they're preparing for future shortages is to store extra tequila in large stainless tanks to be bottled when needed.)

    After agave is delivered to the distillery, it is slow roasted in brick ovens (compared with faster autoclaves that some brands use), fermented in wood fermentation vats, and double distilled. Contrary to industry gossip, Alcaraz says that Patron distills all their own agave, and it is all made at their facilities.

    Gran-Patron-Burdeos-bee-stopperss

    Beyond the regular Patron range, they have two super-ultra-mega=-expensive premium options: Gran Patron Platinum and Gran Patron Burdeos. For the Platinum, they use agave with the highest sugar content, triple distill it, and age it in a large new, uncharred oak tank for one month.  The Burdeos is made from the same raw material as the Platinum, but is aged one year in American oak, then redistilled, then aged 10 more months in French oak, then finished in an ex-Bordeau wine barrel for two more months.

    Alcaraz says he doesn't drink tequila out of the Riedel Tequila Glass
    not because it's not good, but because it's too good. He says it makes tequila taste better than it is. "If there is something wrong I want to taste it!" he said.

    He also said something I've never heard before: that tequila improves in the bottle. That's a surprise, but one I don't think I'll ever be able to test- not only do you have to have a long and great sensory memory, I can never wait around while there's a bottle of tequila nearby.

  • A Visit to Cognac Paul Giraud

    My final visit in the Cognac region of France was to the house of Paul Giraud- quite literally his house. In my brief visit we first learned about Giraud's philsoophy: while other houses try to use blending to get a round and multi-faceted flavor profile, Giraud tries to emphasize particular flavors in each bottling. 

    Giraud2s

    I found a commonality in all the Giraud cognacs though, a strawberry rhubarb creaminess. The Naopleon bottling is meant to emphasize the grape flower aromas, whereas the Vielle Reseve (labeled as XO in the US) emphasizes fruitiness with flavors that change from fresh to dried plum as the spirit warms up in the glass. The Tres Rare bottling, which is delicious, 49 years old and emphasizes spice on the palate. 

    Giraud1s

    Paul Giraud is located in the beautiful little town of Bouteville. There the brand (it's all estate-grown grapes in their products) owns 40 hectares, and they actually harvest about half of their grapes by hand instead of machine. 

    Giraud12s

    Some of the aging cellars are located right next to a stream, keeping them cool and humid year-round. In this cellar like all of them in Cognac, we saw spiders all around. They love spiders in cognac cellars (surely you've seen webs in my other pictures) as they eat the bugs that otherwise may eat through the wood in the barrels.

    You know, maybe I should start using that excuse not to clean my apartment- I'm just trying to protect the furniture.

  • Otard Cognac Visit

    Last month I took a big trip to Cognac to learn about cognac. One of the many houses I visited was Otard. This cognac house is located in the former fortifying castle of Cognac in which Francois the First was born, on the Charente River next door to Hennessy.

    Otard2s

    A tour of Otard is part castle and city history tour, and part cognac tasting. The castle dates back centuries, but my interest really begins when it was purchased by the Otard family after the French revolution.

    In the basement of the building are the aging cellars. As the river is running right next to the building, the cellars have 90 percent humidity, which the cellar master likes very much. 

    Otard cellars

    Otard buys eau de vie from the first four delimited regions- Grande Champagne, Petite Champagne, Borderies, and Fine Bois. On this visit we were able to taste raw spirit from three of them. As noted previously, grapes from the Fine Bois produce spirit that is fruity and aromatic right off the bat, but does't age well for long periods of time. You'd could definitely taste this as a fruity, tasty grape spirit.

    The raw spirit from Grande Champagne was what I'd call tight- seems like you'd want to dilute it a bit to release the aromas. This they tease out after aging in oak. The spirit from the Borderies was, as it's supposed to be, very floral like lily or violet. Many brands use Borderies spirit to add this flavor to their blends.

    Moldys

    Otard is available in the US but not widely so. They do a lot of business at duty-free shops and in Europe, Scandinavia, and Russia.

    Otard also has a release Otard 55 that San Francisco bartenders recommended I try, as it is "natural strength" at 55 percent alcohol compared with the usual 40.  This could be great for mixing into cocktails, but I'm afraid I have bad news guys: This bottling is being discontinued, as they say there was too much consumer confusion about it. Maybe they should have labeled it "Bartender's Blend" instead…

  • A Visit to Courvoisier Cognac

    On a recent trip to France, I stopped in to Courvoisier cognac for a visit. Courvoisier is located not in the city of Cognac, but in Jarnac- one of the two other main cognac towns along with Segonzac. Jarnac appears to be a bigger city than Cognac and looks a bit more lively. I popped in to the tourism office and was told they don't really have any hotels in the city itself, just bed and breakfasts. The real hotels are the fancy chateaus a few miles outside the city.

    Courvoisier dominates the Charente river waterfront here as Hennessy does in Cognac. Can you believe this picture isn't a postcard?

    Courvoisier9s

    The house of Courvoisier is just as beautiful inside as it appears on the outside, though they have a bit of Napoleon overdose in the design theme. Courvoisier was the official supplier of cognac to Napoleon or some such, and they really are running with that. In the visitor's center downstairs, they even have one of his famous hats. (Branding suggestion to Courvoisier: make the Napoleon hat the bartender's new fedora.)

    Courvoisier4s

    Courvoisier only purchases grapes for its cognac from the inner four delimited cognac regions- Grande Champagne, Petite Champagne, Borderies, and Fine Bois. They own two distilleries but work with several others to produce the eau de vie that will go into their bottles.

    A unique thing about Courvoisier is that they pick out the trees that are used to make their barrels, then have them built especially for their use. (Most companies just buy barrels.) They use the traditional Limousin and Troncais forest trees, along with some from Jupille. 

    Le nez de courvoisiers

    While there, we were treated to the La Nez de Courvoisier experience. Basically they take you into a groovy lounge, blindfold you, and blow smells in your face. You have a glass of cognac in front of you and the goal is to try to identify those same aromas in the cognac. They're bringing the La Nez de Courvoisier on the road in the US, but by the time you read this post they will all have happened.

  • Cognac Pierre Ferrand Visit

    One night on a recent visit to France, I visited Cognac Pierre Ferrand. It was awesome.

    Our group had the good fortune to visit Ferrand on the first day of the cognac harvest, and the bad fortune to arrive so late that we missed seeing it. Alas. Still, we had a tour of the still room where during the winter the pot stills run for 24 hours a day. Ferrand actually has three brands of cognac that include Landy and Gabriel, with Ferrand as the flagship brand. 

    Ferrand spirit safe on cognac stillss

    The stills at Ferrand are a little different, as two of them have "spirit safes" on them. These enclosures are required by the government to ensure that all tax is collected on spirit products, but they're not usually required on cognac stills. At Ferrand they make Citadelle gin in the off season, so they had to have the safes installed.

    Ferrand releases blended cognacs without age statements, along with some very old single vintage cognacs including one from 1914. However, they're particularly proud of a more recent vintage 1972 cognac that's a new release to the market. And delicious. Also in the line is Selection des Anges, bottled at the point where the angel's share (that which evaporates out of aging casks) is greater in proportion to what's left.

    Ferrand paradiss

    Speaking of aging, I was going to talk about dry versus humid cellars, or chais. When cognac ages in humid cellars like those along the Charente river, alcohol evaporates out of the casks at a faster rate than water (much like distillation), and the spirits in the barrel loses alcohol content over the years. The good news is that because of this, flavors are more concentrated in the spirit and it needs less dilution to reduce the cognac to bottle strength, which is nearly always 40 percent alcohol by volume. Dry cellars (often located upstairs in the same aging buildings) are hotter and water evaporates more rapidly, so the cognac retains or even gains percentage of alcohol by volume. One blender described the dry cellars as producing dryer and more subtle cognac, while the stuff aged in humid chais was more fruity and flavorful.

    After the tour of the distillery and cellars, we drove to the very modern blending facilities, which happen to be located behind brand owner Alexandre Gabriel's rather fabulous house.

    Ferrand house4s

    We had a long and very fun dinner inside and that, friends, was a great night.

  • Cognac Frapin Visit

    A few weeks ago I went to France to learn about cognac. One of the stops was the house of Cognac Frapin.

    Frapin sells only estate-grown/distilled/aged cognac, produced in the Grande Champagne delimited region of the cognac area near the town of Segonzac.

    Frapin 12s

    Frapin is a massively impressive operation from the cellars to the blending room designed by Mr. Eiffel (yes that one) to the bangin' castle they own where we had lunch.

    We first looked at the bottles, which are unusual for a few reasons. First of all, they sell not only vintage cognacs but multi-vintage cognacs of their "Multimilleseme" line with the three vintages in each. The years are listed on the labels.

    To sell vintage-dated cognac, the brand must be able to prove that it comes from the year on the label. As the government didn't track this until relatively recently, this was a hard thing to prove, but some brands like Frapin clearly had their paperwork in order.

    One thing I didn't notice until I looked on their website it that they have one bottling with a minimum age statement- "15 years old" stating that the youngest cognac in the bottle is 15 years old. I didn't know this was legal in cognac but I guess they are able to prove it. (Other brands have vintage dates like 1980 but not usually a minimum vintage- only a single vintage.)

    Frapin blending rooms

    I stated in a previous post that the aging process for cognac is a dynamic one and I think the product description (taken from the website) of the 15 year old really demonstrates what a cognac can go through before it hits the bottle:

    Aging: Only 6 months in new oaks from Limousine area to preserve the fruit and characteristic of the Cognac. Then, 10 years in red casks (5 years old cask). Aged 8 years in dry chai and 2 years in humid chai. Then the cognac is blended with older cognac Grand Champagne from Frapin to add complexity from the very old Eu de Vie and aged a other 5 years in very old cask in a humid chai to mature the blend. 

    What is the difference between a dry chai and a humid chai? More on than in a later post. Also more on the dusty cellars later. The spiderwebs in cognac cellars are not a bug but a feature.

    Frapin11s

    After the cellar tour, we had lunch at the Chateau de Fontpinot that is, as it looks, rather lovely.
