Brew up the syrup and get yourself a Soda Stream or any other carbonation device and you&apos;ve got a tasty cola you made yourself.&lt;p&gt;Word of warning, making this stuff is SUPER expensive compared to just buying some Coke from the shop. All of those oils are not only hard to find (especially in Australia), but can be quite pricey when you total them up. Neroli oil is expensive in itself (about $25 AUD for 10mls of the stuff) follow the recipe right down to every warning (you could easily end up poisoning yourself if you make it incorrectly). Remember to get food grade, 100% undiluted oils or you could make yourself really sick or as I said, poison yourself.&lt;p&gt;I skipped the caffeine in mine and it seemed fine without it, but probably would taste better with it. I did notice something was missing, not sure if that&apos;s due to the lack of caffeine though I skipped primarily because the dangers of caffeine and the fact small amounts can actually kill you.&lt;p&gt;Don&apos;t go making this if you&apos;re expecting a 1:1 Coke copy. This has its own unique taste, slightly syrupy. I think the recipe definitely needs more work, but considering it&apos;s a free and open sourced recipe it&apos;s pretty good as it is.</text><parent_chain></parent_chain></comment><story><title>OpenCola Soft Drink</title><url>http://www.colawp.com/colas/400/cola467_recipe.html</url></story>
<instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>lobster_johnson</author><text>I love this recipe. I make it now and then so that I have a glass of syrup in the fridge that I can mix with carbonated water from a cartridge system.&lt;p&gt;(For a while we had the cola on tap in the office via a carbonator, alongside a colleague&apos;s home-brewed beer. It was very popular.)&lt;p&gt;I easily prefer this recipe to commercial Coca-Cola. On the one hand, it does lack a certain something that Coca-Cola has, and I attribute this mainly to the fact that I don&apos;t use any coca-leaf extract; you can get this online, and it ultimately comes from the same source as Coca-Cola uses, but I haven&apos;t bothered.&lt;p&gt;But on the other hand, it just tastes &lt;i&gt;better&lt;/i&gt;. Fresher and more vibrant. Very different from off-the-shelf cola syrups such as SodaStream&apos;s. It&apos;s closer to a &quot;indie&quot; cola like Fentimans or Boylan&apos;s. My hypothesis is that Coca-Cola&apos;s current &quot;natural aroma&quot; ingredients are no longer natural essential oils, but synthesized versions of these, although I have not been able to confirm this.</text><parent_chain></parent_chain></comment><story><title>OpenCola Soft Drink</title><url>http://www.colawp.com/colas/400/cola467_recipe.html</url></story>
