coffee sampler

Many items use simple labels like "Caffeinated" or "Non-Caffeinated" (decaf). Some instant or functional offerings list exact caffeine per serving — examples in the results show about 45 mg for a milder roast and about 90 mg for a medium roast.

Pour-over single-serve packs are prepared by tearing, hanging, and pouring hot water through the grounds. Instant packets are mixed into hot or cold water; some listings note a quick prep time (about 30 seconds).
