Frequently Asked Questions
Can I make cold brew on the beach without gear?
Yes. Instant sticks or powders dissolve in cold water and require only a bottle and ice. For ground coffee, use a simple brew bag or steep coarse grounds in a sealed jar and strain with a towel or fine sieve — but that requires more cleanup.
Which option makes the strongest concentrate?
Coarsely ground single-origin dark roasts intended for cold brew (like the Colombian Reserve) create the most concentrated, long-lasting iced coffee. Instant concentrates can be strong too, but whole-bean cold-brewing gives you fuller body and control.
Are MCT- or vitamin-infused instant sticks worth it?
They’re convenient if you want added energy or functional nutrients without extra supplements. Customer experiences vary: many report sustained energy and appetite control, while others say the effects are subtle. Consider taste, price, and your dietary needs before choosing.
