I used to drink straight from the bottle (I don't know if plastic container of 2 liters is still considered a bottle), but now I better like it poured into some sort of glass. mainly it's so that the bubbles in beer wouldn't disappear while you are shaking and drinking these 2 liters. It's tastier to keep the big container closed. It's nice to read about these improvements that the glass gives for your beer though I'm skeptic, but if you say that it tastes better and that's not placebo, then ok.
