Wikipedia tells me Kvass is basically an improvised fermented beverage made from stale bread. Something like applejack, but typically made from scraps of old rye bread instead of apple scraps. This sounds like your brown, thin, and sour drink. Looks like this one: http://www.npr.org/sections/thesalt/2013/08/14/204859046/america-are-you-tough-enough-to-drink-real-russian-kvas

Wikipedia doesnt go into a lot of detail but recipe sites seem to offer possible clarification. There's a wide variety of Kvass types, some are heavily flavored with berries etc and the color can range from brown towards the pinkish with those. There's also something called 'beet kvass' that is very pink and not at all brown.

So I am thinking at the Myu Myu you had a very upscale foo-foo sort of kvass either heavily flavored with something pink, or possibly even made from something pink like beets and/or berries with little or no bread at all, while at the market you got 4 liters of cheap brown kvass.

Some more pink-hued versions:

What you got at the bar might have even been a mixed drink of some sort that merely used kvass as an ingredient as well.

You have me curious and I am still hoping to hear a genuine Russian or at least eastern european response.

I Googled 'pink kvass' and the first link that came up was this blog post.

My life is now a recursive nightmare.

Thanks a lot, pal.

Or you could move on to the second link and avoid the recursion.

Google does tailor results to person, perhaps it knows you only care about CN?

When I google pink kvass I get pictures of cubed beetroot, and link after link to recipes involving beets.

Hm, well, ll the recipes for beet kvass that I see indicate that it will be an acidic/salty taste. Looks like I'm going to have to go to Moscow again.
