Sorry Lucha! I just committed a 110 pesos mistake! Was just at Walmart to buy some tea (they usually have Earl Grey, nada hoy) and thought I'd give some other coffee a try since our Starbucks grains are now running about 360pesos a kilo! The Cabrales they had was ALL torrado, yuck, so decided to go for the 500gr bag of 5 Hispanos tostado natural en granos "especial para maquinas express" -- well, that was a BIG mistake, lol. Maybe it is another kind you use? All the others en grano they had were torrado as well though. But just got home and ground the beans at the setting we usually use, made a single espresso and it's got that horrid burnt flavour that you get so often here. Since I don't like to waste, I'll probably just be mixing it in a little at a time with our regular beans.
So still on the search for a cheaper option than Starbucks beans without sacrificing flavour -- how much are the prices at Estacion del Cafe (or Bolsa de Cafe?) -- the one on Pueyrredon? I never am down there but may have to make a special trip of it.
