That all looks delicious!
I find the BBQ discussion interesting. It indeed shows what Zardnaar said about different cultures having different styles of barbecue. Where I'm from, we'd call this a cookout (and a pretty good one at that), which applies to any time you grill food outdoors. Barbecue implies having a barbecue sauce, which is usually tomato-based (although I hear they do it differently down in Alabama). Even the direct/indirect heat difference Oerdin mentioned isn't quite how we see it here; one of my friends cooks meat on a smoker every year that isn't 2020, and it's delicious, but we don't call it a barbecue because there's no barbecue sauce. Instead, we call it the annual smokeout.
Is Russian beer common in New Zealand? I can't recall having seen any in America, although I have seen Russian (and Ukrainian) kvass, and Russian (and Polish) vodka.
