Permanent Brew is the Alchemist's path 1 tier 5 upgrade in Bloons TD 6. It upgrades the Alchemist's buffs - both Acidic Mixture Dip and Stronger Stimulant - to become permanent instead of lasting only a limited time. Only newly thrown AMDs and brews are permanent, and brews cannot affect targets that already have a brew of any kind. If Permanent Brew is sold or sacrificed, all towers lose the buffs it had applied.

Permanent Brew is a very potent T5 for permanent Stronger Stimulant and Acidic Mixture Dip buffs to large amounts of towers surrounding this Alchemist; each tower essentially gains +2 damage to Ceramics and MOAB-class with extra pierce, attack speed, and range, in addition to lead-popping. It's quite an expensive T5, but with an effective mid-game saveup, this can be afforded in CHIMPS in time for the mid-80's on most maps. It stands out the most on Least Cash Bosses, which demand an army of cheap highly buffable towers against all Boss stages, and extreme Freeplay, which demand maximum buffs on every tower on screen.
Despite its low range and the restriction of not selling or sacrificing to retain its buff, there are multiple ways to counter this. The simplest is Support Chinook; it allows the Permanent Brew to be moved without towers losing its buff. Dark Knight and above can also be moved around the map to keep adding new targets later on. A few maps do have movable platforms that can allow Permanent Brew to keep finding new targets, with a notable example being Geared's smaller gear.
Crosspathing with Permanent Brew largely doesn't matter, as its brews are permanent anyway. However, in a time-sensitive situation such as Boss Events, Faster Throwing is the optimal crosspath, so it can brew all nearby towers faster.

Permanent Brew is strong in the right use, but just to let it live up to more of its potential without requiring a chinook we are improving its range. — Update notes
Alchemist 220 stands out a little too effectively in the crosspath efficiency of Acidic Mixture Dip uptime combined with the reduced forced downtime at 320 and so is being reduced. — Update notes
Permabrew itself granting a range increase was annoying to prepare for and also somewhat hurt what was a very strong synergy for Chinook, so we’re taking away this bonus range but giving enough of a cash difference so that it can pair up with synergies like the Support Chinook more easily. — Update notes
All buffing potions: Should no longer fall on other towers that aren't the intended target (bug fix)
Note: Patches an exploit regarding quickly buying a Permanent Brew and landing brew on towers not normally able to accept brew (e.g. Etienne, Beast Handlers, non-5xx Villages)
Acidic Mixture Dip: No longer targets Nature's Ward Totems (bug fix)
Acidic Mixture Dip: Can now target 5-X-X Monkey Villages (bug fix)
Brew: no longer applies the range buff twice (bug fix)
