How To Make Beer and Wine Popsicles, Win at Life Using Science

Notes From A Queer Engineer_Rory Midhani_640

Hey, remember that time Liz Castle made boozesicles with Piña Colada mix? How about when Ali set our hearts aflame with Bourbon Hellfire Fudgesicles? Ooh, or when Vanessa made out with a cute girl on a rooftop after a couple French 75 popsicles? What I’m about to share isn’t a new idea, but times are hard, life is short, and dammit, we all deserve something good right now!

Enter beer and wine popsicles, aka the secondary coping mechanism I’ve developed to get myself through August 2017! (The primary one is working myself into oblivion.)

My adult popsicle experiments all began with a Lifehacker article titled “How to Turn Any Alcohol You Like Into Tasty Frozen Popsicles.” Per Claire Lower,

To make an alcoholic ice pop that won’t slush out the moment you remove it from the mold, you’re going to want to aim for an overall ABV of 8%. Some beers fall under this threshold, so you are free to freeze those as is, but you’ll need to do a bit of math when working with the stronger stuff. Luckily, it is very easy math. Using the basic dilution formula that you may have learned in chemistry class, we can quickly find how much booze we can add to our popsicles: C1V1=C2V2 where “C” stands for “concentration” and “V” stands for volume.

Popsicle 1: 14.5% ABV red wine and mint popsicle. 50% dilution with sugar water.

Following the dilution formula above, I mixed one part water with one part red wine (14.5% ABV), making an easily freezable popsicle that came in around 7.25% ABV. I also stirred in a teaspoon of sugar and some chopped mint leaves. Result: a refreshing, wine-like popsicle with very large ice crystals. Very hard, very cold, not particularly nice for chewing. Also not the most alcoholic. A solid first attempt, but I knew I could do better!

For trial number two, I decided to go with beer. Not thinking too hard about it, I poured an oatmeal stout named “dessert” into the freeze pop mold, added some raspberries, and stuck it in the freezer. When I came back one day later, it was much meltier than expected. Turns out the ABV of that beer is 11%. And the taste of that beer, friends, is heaven on a plastic popsicle stick!

Popsicle 2: 11% ABV beer and raspberries.

Texture wise, there was still room for improvement. The beer was great (you could bite into it and it felt like a pretty normal popsicle), but the raspberries inside were solid little ice cubes. Delicious, but jarring! Further research into the matter yielded the following key facts:

  • Pure ethanol has a melting point of -173ºF (-114ºC). In contrast, water has a melting point of 32ºF (0ºC).
  • The amount of ethanol in the most common commercially-available alcoholic beverages (by volume) is pretty low: 4-6% for most beers, 12-15% for most wines, and 40+% for most liquors. The rest of the volume consists of water and solutes (salts, sugars, etc.).
  • Most home freezers maintain temperatures between –9ºF and 0ºF (–23ºC and –18ºC).

What this means is that there’s nothing special about 8% ABV. So long as your freezer is colder than the melting point of your liquid, it will freeze. It just might take a long time if the ABV is high, and when you take it out of the freezer, it’s going to melt more quickly, potentially requiring you to shotgun your alcoholic popsicle. Challenge accepted.

I went for wine next: a 13.5% ABV chardonnay, plus blackberries. I stuck a wireless digital thermometer in the back of my freezer and measured the temperature range: -2ºF to 4ºF over the course of a normal week. Not bad; and with a little patience, it’s definitely cold enough to freeze my wine.

Popsicle 3: a 13.5% ABV chardonnay and blackberries.

Here’s some more science for you!

  • Hydrogen bonds (the attractive force between the hydrogen attached to an electronegative atom of one molecule and an electronegative atom of a different molecule) are the reason why water forms ice crystals when it freezes; they naturally create an open hexagonal lattice.
  • Any molecule containing what is called a hydroxy group (-OH) or an amino group (-N-H) is capable of forming hydrogen bonds with water. Sucrose (table sugar) contains eight hydroxy groups, making it very soluble in water. It actually bonds so well with water that it literally slows down the motion of the water molecules.
  • The more sugar there is, the lower the freezing point. Sugar physically interferes with the growth of ice crystals, and smaller ice crystals translates into less graininess in the final popsicle.

To cut down on the “ice cube” texture, I chopped my berries into smaller pieces and coated them in sugar. My popsicle turned out splendidly.

Popsicle 4: 12% ABV rosé and strawberries.

I didn’t actually get to try this out yet, but honey is another sweet option to lower the melting point. The sugar in honey is mostly fructose and glucose, two “small sugars” that lower the freezing point and prevent iciness even better than a larger sugar like sucrose. Light corn syrup is another option, preferred by Cook’s Science for decreasing ice crystal size and raising the melting point for ice cream. For something that doesn’t add sweetness at all, gelatin or carrageen are two other options. Those two also thicken things up and reportedly lessen the overall meltiness.

What popsicle combinations are you going to try?

  1. I often make non-alcoholic adult flavour ice lollies by simply buying drink mixes and freezing those. Perennial favourites on hot summer days include piña colada and mojito. Just an idea for those of you who like the idea of alcohol lollies, but like me eat them at times when alcohol is a really bad idea.

  2. I came to admire glorious science and share a recipe my local newspaper published for in a publicity piece for “The Poptail Manual” by Kathy Kordalis. OvO

    Kahlua and Coffee Ice Pops
    12 ounces cold coffee
    4 ounces cream
    4 ounces Kahlua

    Mix Kahlua and coffee in a pitcher, pour into ice pop molds
    Freeze for 12 to 14 hours.

    I haven’t made this as I do not have pop molds yet, so if anyone makes it tell me about it. I fucking love Kahlua.

  3. Here’s an idea using a chocolate mold for a shot glass, make the chocolate shot glass, then pre mix the Kahlua and coffee and then add it to the chocolate shot glasses you previously made and then freeze them for the same time.

    Or perhaps just freeze the chocolate shot glasses and add triple sec to them.
