2-3 years ago many grocery stores added other milk alternatives. While I think almond milk is the best, oat milk is the second place but much cheaper.
Generally, milk is heavily subsidized in Germany and alternatives are 2-4 times more expensive, so I don't know if this a little hype or the start of a lasting change. Milk costs like 0,60€ a liter, oat milk costs 1,50€ and organic almond milk can cost up to 4€ a liter.
