         | Yes, this video (and HN commentary

         | "the experiment didn't fail, it successfully eliminated one of
         | the possibilities" is very scientific.

           | The trick to have well carbonated beverages if all you have
           | available is a sodastream-like device:
           | 
           | - cook the water to remove any other disolved gasses
           | 
           | - Cool it down to as cold as you can. A sludge of ice and
           | water is very close to zero degC
           | 
           | - keep some ice unmelted
           | 
           | - carbonate
           | 
           | This is a bit annoying to do especially step one (I skip it,

         | Right? In the summer, there's two things I drink. Cold water
         | overnight infused with whatever (lemon, cucumber, mint, etc)
         | and carbonated water from the store. Both are cheap to make and
         | pleasant when it is hot. Neither has added sugar. You can also
         | infuse with fruits like strawberries. In the other parts of the
         | year (esp. winter) I make a can of tea (nearly 1,5l) with two
         | teabags. One cup of tea is about 0,2l so it will last the whole
         | day, and it stays hot for 24h. Make in morning and you got
         | whole day together (we are two drinking this). Sometimes goes
         | to waste cause of being away, too hot weather. There's a lot of
         | good fusion brands available (I like Yogi Tea's blends a lot),
         | you can also make your own herbal mix. Just be careful with
         | some herbs and medication.
         | 
         | The carbonated water and lemon in water make for an acidic
         | liquid. This is nice when it is hot, but it is also bad for
         | teeth. So I do try to limit these somewhat, never drink it
         | right before brushing, brush 2x a week, and floss with those
         | special toothpicks. I also drink the acidic stuff with the main
         | meal in evening when the teeth already get a blast from the
         | meal, regularly at least.
         | 
         | As a former wine drinker (who can also appreciate special beers
         | and heavy liquor) I was not able to stick to one beer on friday
         | evening, and I recognized the struggle to battle an addiction,
         | being an alcoholic in disguise. I've been sober past years,
         | approx 4, apart from an occasional mistake due to alcohol in a
         | desert or an intentional tiramisu during Christmas.
         | 
         | I also still drink coffee, but with caffeine not so much.
         | Mainly in morning/afternoon. As a kid I was a fan of cola, the
         | coca cola one (for some reason never liked other ones like
         | Aldi's or Pepsi much; there's a lot of choice these days). Club
         | Mate is a bit hard to source and the pfand is annoying
         | (justified, but...) to send back from NL. But I been able to
         | quit that in puberty. So, while I like cheap/bulk, I am not
         | sure what I could gain from DIY soda (the carbonated water is
         | cheap and we get the groceries at the doorstep, also useful
         | since we don't have a car).

       | I think you'd end up paying less, too. I paid about 20 bucks for
       | the concentrate bottle plus shipping, made 1.75L of it, thought
       | it was _fine_ but couldn 't quite replace Coke in my diet, and
       | didn't buy again. Had I done it all from scratch, I'm pretty sure
       | I would've paid more and had a bunch of essential oil bottles
       | leftover, going to waste.

           | 
           | I used like half the amount of sugar the cube-cola recipe

       | 
       | Tips for working on sugar-free recipes: In some countries (like
       | Canada), soft-drink manufacturers are required to disclose the
       | exact amount of each artificial sweetener they use in the drink.
       | So you can easily grab those numbers from Canadian product
       | listings for use in your own recipes. E.g. 355ml of Diet Coke
       | contains 131 mg aspartame + 15mg ace-K.
       | 
       | Also, aspartame can be difficult/slow to dissolve. It dissolves
       | better in solutions with a low pH and a warmer temperature.

       | Also, consider just using water soluble flavor concentrates and

       | This probably won't work for Cola as I think some of those

           | A food seller isn't allowed to cut out a grocer because they
           | are too small. However, I believe they get around this today
           | by having minimum order sizes that make it impossible for a
           | small grocer to handle.
           | 
           | That's effectively how my small hometown grocer was driven
           | out of business. The suppliers refused to work with them
           | because they wanted them to order huge amounts of product
           | that wouldn't work for my hometown with 300 people. So, the
           | people running the store ended up just buying products from
           | either costco or another grocery store a town over. The price
           | hike they had to apply was simply too much for the local folk
           | who ultimately also went to the nearby towns to save money
           | instead of shopping locally.

       | I recently started getting into homemade ClubMate production. The
       | goal was to create a drink that has caffeine, less sugar than

       | 
       | It took me 4-5 tries to get to a recipe that tastes good. Earlier
       | tries involved cooking the mate, which led to a bitter taste.
       | Cold brewing led to way better results.
       | 
       | Here is my current recipe for 5 bottles (a 0,5l):
       | - 60g mate tea leaves (coarse) [1]       - 500ml water       -
       | 65g cane sugar       - 1 squeezed lemon       - soda water
       | 1. Add 60g of mate to a 500ml bottle and fill up the rest with
       | water       2. Let it sit in the fridge for 12-24h       3. Then
       | strain the mate from the liquid       4. Use a filter cloth or a
       | tea towel (soak with water first)   to filter out the remaining
       | suspended solids       5. Put sugar and the lemon juice together
       | into a pot and start caramelizing the sugar       6. Then add the
       | filtered mate tea and take the pot from the stove       7. Now
       | distribute it equally on the 5 bottles and fill up the rest with
       | soda
       | 
       | The mate tastes less sweet than the original mate, but is still a
       | great drink to keep you awake.

         | 
         | One is a couple of squirts of vanilla, a couple of squirts of

         | crammed full of sugar, which I can 't do much about.
         | 
         | I also have a mix I keep around made out of 3 tablespoons salt,
         | 1 cup vanilla, 1/2 cup lemon juice, 1/2 cup lime juice, and
         | about 1/3rd cup almond extract. I measure it all (except the
         | salt which I just put in directly) into a single 2 cup Pyrex
         | dish and just sort of eyeball the last 1/3rd cup of almond
         | extract, then funnel it in to a holder. I use McCormick 32 oz
         | vanilla and almond extract for this and order bulk RealLemon
         | and RealLime juice for this from Amazon, and mix it into one of
         | the leftover bottles and keep it around refrigerated. 3 squirts
         | and "whatever dribbles in" as I'm removing the bottle is what I
         | used for one DrinkMate bottle. To taste, as all of this is, of

         | You can also mix unsweetened electrolytes in, but you have to

         | react with the lemon & lime juice. Salt you can keep in the mix
         | but not electrolytes in general. It adds a certain body to the
         | mix even if you're not interested in the electrolytes _per se_
         | , and a single packet of them lasts a long time.
         | 
         | You're not going to go into business selling this stuff, but if

         | lemon/lime juice as a beverage flavoring we might just have
