Vodka

"Vodka is a clear distilled beverage most often made from fermented potatoes. Thousands of flavors exist, but they all serve one main purpose: to get the imbiber completely shitfaced drunk." Vodka is a new type of alcohol added by the Bottling and Booze expansion. It shares the lowest addictiveness of the distilled alcohols at 3%, but provides the second lowest recreation at 18%, only above Moonshine. Vodka is also used to distill the more valuable Rectified Spirits.

Acquisition
Vodka can either be bought from Alcohol Traders or distilled from Potato Mash in batches of 3 per 35 Mash (at a ratio of 1 potato:1 Mash), which is created by fermenting potatoes for 15 days in the Vodka Fermenting Barrel. Because the Barrels are directly filled with potatoes, caution is advised as haulers can deplete your entire supply of potatoes if enough Barrels are present.

Crops per Barrel
Below are the minimum minimum numbers of potato plants that must be planted (under varying conditions) to assure enough potatoes are always present when ready to brew a new batch of Vodka.

Other
For other soil fertility values, this value can be calculated with the following equations:

35 / 11 / 5.8 / ((1 + ((F-1) * .4)) / (32,500 / 60,000)) / 6

General Formula: Amount per batch / (harvest yield / (growing time / (1 + ((fertility - 1) * fertility sensitivity)))) / days per batch
