yeah the sierra nevada and courage imperial russian are rated really highly so i think i'm definitely going to grab those two. i think the coffee one might have been the most expensive of the four (nz$15 for a bottle compared to $8-11 for the others). yeah i hear you about the coffee flavour too, but man i am really big on coffee so any enhancement to the coffee flavour is something i am probably keen to at least try. could just get two of the courage instead. :p
also i really need some good beer glassware, no shops around here tend to have glassware beyond wine / flute / cocktail glasses. :/
