BloomBerry wine: Master Vintage score, yeast and aging

Put two small BloomBerries and yeast into a Wine Bottle, fill it with 750 ml of Basewater or High-Quality Water, and press Start Fermenting. That combination scores Master Vintage (175 credits before aging, +75%). Finished BloomBerry Wine gains 3 credits of value for every day it ages, and Reserve and Master Vintage bottles also count as Luxury Items.

Getting started

Retired Winemaker from Wild’s Network costs 200 credits and gives 3 Wine Bottles, 3 Yeast, 2 BloomBerries (one good, one underripe), a Water Ration, a Magnifying Glass and the fermenting guide. He visits weekly with 4 bottles, 4 yeast (each of two has a 25% chance to be Super Yeast), 2 water rations, 1–8 BloomBerries and, 5% of the time, a Yeast Bioreactor. Dr. Jackson starts stocking the AgeWell.

Quality score

Factor	Points
Each berry	Small +2, Normal +1, Underripe 0, Moldy −1
Using two berries	+1
Using yeast	+1
Water	Depends on its grade

Score	Grade	Value before aging
6 or more	Master Vintage	175 (+75%)
5	Reserve	150 (+50%)
3–4	Production Wine	125 (+25%)
2	Homebrew	100
1	Bucket Brew	85 (−15%)
0 or less	Undrinkable	Worthless

Two small berries (+4), two berries (+1) and yeast (+1) make 6 before water. The fermenting guide says to use High-Quality Water or Basewater: Pure Water lacks the minerals fermentation needs, and lower grades greatly reduce quality. Check every berry with the Magnifying Glass; feed moldy ones to animals.

Yeast and fermentation time

Yeast	Nights	Notes
None	4	Wild yeast from the air gives inconsistent results.
Yeast	2	Used up.
Super Yeast	1	Used up.
Yeast Bioreactor	2	Returned when fermentation starts; reusable.
Synthetic Yeast	2	Makes GloomBerry Wine.

You need at least one berry (or Synthetic Yeast) and a full bottle.

Aging

Each night a bottle of BloomBerry Wine ages one day and gains 3 credits of base value. An AgeWell (350 credits, 24 energy a night) ages every bottle inside by extra days; each 125% Quality from modules adds one more day per night. A Fridge does not help wine.

Example. A Master Vintage bottle kept 20 days is worth 175 + 60 = 235 before your markup.

GloomBerry Wine

Synthetic Yeast and water alone make GloomBerry Wine, worth 44 credits. It does not age, it is Mid-Level contraband, and selling it counts as Consumer Endangerment on your Security Record.

Growing your own berries

A Hydroponic System yields 6 BloomBerries every 2 nights after the first 3-night crop, and the bush regrows by itself. Cleaner water gives better berries: at 86–100% plant health, 40% of berries are +1 and 60% +2 condition. See the hydroponics guide.
