This pdf is 12 pages long, 1 page front cover, 2 pages SRD, leaving us with 9 pages of content, so let's take a look!
Concept-wise, this is the first of a collection of pdfs focused on tight subjects - this time, framed by short narratives, we are introduced to dwarven fire ale and elven absinthe - and boiy, they are cool: Fireale e.g. affects you with rage for a couple of rounds and thereafter nets you a cold resistance for its consumption. And beyond its effect, these liquors also feature a drawback for their consumption and a short line on their actual taste - neat! Beyond these, we also get racial/national liquors - catfolk nihp nets you a 10% chance per minute to get access of a detect-spell, but at the cost of 1d2 dex and darkvision: Interesting, but it fails to specify whether there's a level-cap for the detect-spell or not.
Fetchling rainbrew may be actually rather hazardous - you can accidentally breathe color sprays when ingesting it. Ratfolk-drink, healing Tengu Baju, an Urisk-brew that temporarily nets access to a limited form of bardic performance. There also is an Erkunae-drink as well as some that are local specialties that net you some cool insights into the world of Porphyra - e.g. 3 magical whiskeys of the lands of the Fenian Triarchy.
We also get information on diluted spirits and creating magically-infused liquors.
Editing and formatting are very good, I didn't notice any significant glitches. Layout adheres to a printer-friendly one-column standard - which means that you can probably fit up to 4 pages on a given page if you print it out - I would have preferred a more standard layout. The pdf comes fully bookmarked.
I really love the idea of these liquors and their execution and fluff per se is nice indeed - but what's not so great is that the pdf fails to specify, when applicable, the caster-level of the spell-like effects the respective liquors entail. That being said, this pdf is "Pay What You Want" - you can pay as much as you'd like for these liquors and they indeed are worth a look. While not perfect, it is a nice offering and thus worth 4 stars.
