I am drinking my Soylent mixed with cold "brewed" coffee, and it's delicious, I want to wolf down the whole glass. Welcome to your new Soy-latte. It helps that I started with a cold press coffee from a coffee hut near me that makes some of the most delicious coffee I've ever had in the first place. Definitely worth doing. I didn't get to trying all the extracts we bought this weekend, life you know. I blame it on the traditional food meal the wife and I had, it skewed our normal soylent flow. I will report back when I get to them.
BTW if you are going to try the cold press coffee in the blender it foamed up ALOT before adding the powder. If you make strong cold press and have to cut it with water, mix with the water first then add your coffee for less foam up. I also waited to add the oil to the mixture until this morning after letting it sit overnight, that's just my way now.
