This one's easy, Underberg is getting more prolific in the US, often in pharmacies and many German stores. All over the internet too,
has them for a pretty good price. You can also do yourself a favor and pick up a bottle of Chartreuse and use that ;)
We do sell simple syrup on our store but you can also make some yourself, it's simple!
