Yes - Sweet Marias is awesome. Their sampler packs are an easy to get started. I usually peruse their latest arrivals and pick a pound or two of several different varieties, based on their cupping notes to get an idea of the expected flavor profile. E.g.
>> There's a maltiness in darker roasts, that is like sugar in the raw. The cup is smooth, sweet, and with a touch of malic tartness in the acidity. There is a lactic quality too that reminds me of fresh cream caramel, which plays off flavors of apple juice nicely. At Full City roasts have a juiciness to them with a slight tart note, like cranberry grape juice. The mouthfeel is silky and with a finishing flavor of sweet cocoa. City+ to Full City+.
