Update: Tried 15h, 20h, 48h (still in progress)
The 15h is certainly under extracted as there’s hints of sourness.
The 20h didn’t have any sour taste, but tasted quite bitter. I compared it with my store bought cold brew, which tastes great. I’ll try to experiment more on the grind size or different beans.
I actually DIY my plant milks as well as its super expensive here (developed cow milk intolerance lately 🥲 ). Been rotating between oat milk and cashew milk. I think I prefer cashew milk to my coffee though there are times I crave coffee + oat.
If you plan on DIY-ing cashew milk, I suggest to use “raw diced cashews” variety as it’s half the price of a regular cashews.
Update on the 48h. I actually forgot about it and steeped for another 10h. So a total of 58h. Surprisingly, it’s the best tasting of the 3 I did. I actually drank it black, it’s good without adding anything. Or maybe I developed a preference for over extracted coffee. Lol
Thank you so much for your advice, I would have been cursed forever with underextracted cold brew without it! I wish you all the best coffee in the world!! ☕☕
