Ironically, the only place I've found Ukrainian kvass is in small supermarkets run by middle easterners.
I explained why middle easterners are often better integrated: they've often been here for longer, and they're usually here to stay. EE right wingers overestimate how much they have in common with us, and have the usual hang-ups about Islam.
Easy. I've bought it in Kiwi in Hemsedal (Ulsåk) several times, for example. All Eco Market shops in Oslo as well (run by Ukrainians/Poles btw).
Immigrant shops are your best bet, it's true.
The immigrant store 150m from where I am right now stocks several brands of kvass.
Most likely these workers are working as remote contractors as people still 'based' in Ukraine. (ukraine bank accounts, etc.)
It is much easier to wire money to a ukranian bank account than one in Syria, due to sanctions and other reasons.
By quick google, Norway now established 8000 places for Ukrainian refugees. They in fact took in Syrian refugees too looking at google results - finally ending up with 30000 additional people over that.
And third, the bad situation of Syrian refugees is also because surrounding countries do close refugees to camps with no future for them. No one ever seem to blame them.
It is a little disingenuous to blame Russians for Syrian refugees, given that we already had tens of millions of people that left Syria before Russia joined the party started by IS and other Islamists and escalated by the US/NATO.
Most of the Syrian refugees came to Europe during the summer of 2015, before Russia even joined.

If we were to be nitpicky, we can even say the number of refugees from Syria in Europe decreased after Russian intervention.
