We used to catch pidgeons with bird seed soaked in vodka. They can not fly then. BUT, The vodka would do absolutly nothing to keep the goose from beating you with its wings. Catch a goose from behind and hug them with their wings closed and have some one else remove the string.
Second note. If the geese get too much vodka they could get achohol poisoning or drown. We never had water to deal with when catching pidgeons.
You could use a throw net used for catching minnows for fishing, if you could get close enough. But again, geese have hollow bones so they can be light enough to fly. Too rough and you'll bust a wing and then have to put them down.
