Dear Bruce,
What colour snow to eat depends on your taste.
White snows:
Fluffy and white - Cool and refreshing with no taste except for oaky peaches I reccommend Ruapehu Estates "June 09" very drinkable today.
Dirty white - a gritty drop with moraine dust undertones and blackberries. Garden of Eden easter is a chewy drinker in this price range.
Pretty blue - hard deep winter ice, under pressure with smoky strawberry undertones. Nice to look at but difficult to drink 45m up a free standing pillar at Wye Creek.
Sickly green - hard ice. Aoraki summit 09 is a nice drinker with a slight hint of unwashed armpit over apricot sulfates.
Yellow Snows:
Light yellow - well hydrated lunch piss is a reasonable drinker which isn't too different from fluffy and white.
Medium yellow - tangy. More like a morning vintage outside a hut. Goes well with red meat and porcupines.
Dark Yellow - a rich drop, "I didn't drink all day cos my feet were cold" is one of my faves of this vintage. Well priced! Impress her!
Kinda orrange - Only the most robust of pallettes can handle this. "24hrs out without a drink bottle" is a well priced edition.
Red snow:
Glacier algae - kinda freaky this drop, leave it for your teenage kids or spouse if you're in the Rolling Stones.
Bit the ice-axe while falling - this is a salty drop with undercurrents of moluccan spices. Nice! But don't confuse with...
Carrol Hut toilet 04 - not a great drop.
