I recently bought a Nespresso vertuo machine, it's a BNV220, which I think was the original machine model (unsure?). anyways the machine was $20 and I've cleaned it, and tested it with some pods from Walmart. it was good but looking for pod recommendations, what are the best taste, most cost effective, and best overall pods to make iced lattes with? should I only buy double espresso pods?
