For those interested, none of the major health food shops carry "fresh" almond milk in Hong Kong (at least none of the 10 or so that I've looked in). You can get powdered almond milk at some stores. The fresh non-soya alternatives are rice milk & oat milk (made by Pure Harvest or So Natural).
Rice Milk - at Wellcome super-stores (So Natural brand)
Oat Milk - at Gourmet + Sogo + some health stores (Pure Harvest brand)
Powdered Almond milk - below shop has it...
