i haven't heard of pea milk before and haven't tried goat's milk but i'd be down to try both. i'm always interested in trying different milk alternatives. i grew up drinking cow milk but it's like neutral to me now that i've gotten to try other milks. i prefer almond/soy milk to be flavored like vanilla flavored cause otherwise they can be a little too bland imo. these days, i really like oat milk so that's what i've been adding to my coffee.
