This is specifically for craft: alchemy, and with use of the feats signature skill and master alchemist so you need to be at least level 7.
Lets say a Gnome with a +4 int mod and skill focus on craft alchemy, and all 7 levels he puts a point into said craft. Decides he wants to make some Dwarven Stout. The DC for this would be 15 (High quality item, and since alcohol is a drug it is an alchemical item) And he decides to accelerate the craft making the DC a nice 25. With a +21 on the check and a full alchemists lab the Gnome decides to take 10, making his craft check a nice 33.
This is where it gets silly.
With the first tier of Signature skill; Craft the skill-check is doubled before being multiplied by the DC. Making it a whopping 66, meaning this gnomes weekly progress is 1650. and with master alchemist any alchemical items you make are progressed by their gold values instead of their silver values.
Dwarven Stout is 1/2 a pound, meaning two servings (8cp) is a pint. You can fit 600 pints in a regular barrel (75 gallons). Translated; Dwarven Stout is worth 3gp a barrel.
Using the crafting rules by RAW and doing a single days worth of progress; you can make more then 78 barrels of Dwarven Stout in a 8 hour period. That is 5850 gallons of tasty dwarven tradition in a 8 hour period, or 731.25 gallons a hour, or 12.1875 gallons a minute.
It's not glamorous, and it's not gonna slay any dragons (unless you plan to molotov it to death) But by the entire pantheon you and every village, town, hamlet, city, and random encounter within a 600 mile radius of you will be so hammered they can't do a thing for a week.
