    nice production but i prefer coffee slushees to beat the heat. just brew, freeze & blend. no other ingredients or ice to dilute coffee flavor. maybe you can make a video about coffee slushees. thanks.

  • Martin Christiansson

    Nice video, but you never mentioned the origin of Espresso Tonic. It was Koppi in Helsingborg at their former cafรฉ! ๐Ÿ˜Š

    This makes me want to revisit Prague.

    Tomo mentions he uses “cold brew concentrate”. Is it something different than standard cold brew? What is the recipe?

    • European Coffee Trip

      Thanks for the question, we should also do a video about it, right?

      So Tomo uses 170 grams of coffee to 800ml of water, grind size as for french press and keep it macerating for 12 – 24 hours.

      For drinking as black coffee, you should dilute it 1:1 to 1:3 with water. Hope it helps!

    I am asking from my experience: Is it normal to get a thickening fizzy foam when you pour your espresso shot over the tonic drink? I almost always have to remove it before drinking it. Any tip to get rid of it?

    • Gabriel Hakulรญn

      Happens to me when I pour the espresso too quickly, doesnโ€™t happen if I do it super slowly specially over ice

    • Tomo Laca

      you can filter your espresso ๐Ÿ™‚ try aeropress or V60. But that is the point that cold brew is better in many ways ๐Ÿ˜‰

      This happens to me too. I think the espresso needs some time to cool down and you have to pour it very slowly over ice,

  • Ivo Petrovski

    How do you make cold brew concentrate? DO you have ratios?

  • Jason Bollman

    Have to give this a try

    Just last month I made myself a tonic syrup using cinchona bark extract (filtered through a 5 micron filter) and some other spices and herbs and was joking around that I didn’t think it would mix well with coffee. Apparently I’m wrong and will have to try making this.
