Ohhhh....I love those local micro brews. You can always expect to get a unique flavor/carbonation combo.
Now, imagine a self-serve beer station where you can pay with you mobile + any popular crypto! I'm sure someone out there is already working on one.
You can discover some hidden gens almost every time when you are trying micro breweries while travelling. As you said, not even 2 are the same with all the unique flavours and carbonations.
