Short answer
Umami is an alchemy brew whose runes total exactly 4 green and 4 blue. The formula comes from the Advanced Alchemy technology and needs Laboratory II — a working mix is Night flower + Honey + Honey. At the Kitchen Table, 1 silver item + 1 Umami becomes gold quality: Wine, Grape Juice, Vegetable salad and Bowl of sauerkraut. The Alchemist also sells it from level 3.

The rune formula
Target: 4 green, 4 blue, no red. There is no two-ingredient mix, so you need Laboratory II.
Honey is the easy base: Night flower + Honey + Honey, Minced Meat + Honey + Honey and Hops + Night flower + Honey all work.
Honey comes from beehives — see our beehive guide. Each brew also uses 1 Alchemy Flask.
What it upgrades
Umami works at the Kitchen Table, one item at a time: 1 silver-quality item + 1 Umami gives the gold-quality version.
The four items are Wine, Grape Juice, Vegetable salad and Bowl of sauerkraut.
For wine, the craft takes 8 ticks and needs the Advanced Alchemy technology.

Why gold wine is the big one
Two quests ask for gold Wine: Inflation wants 3 and The Lord's Vintage wants 2.
After Inflation, the mercenaries are paid in wine — 3 gold Wine per hire — so a steady Umami supply keeps hired fighters affordable.
Our gold wine guide compares this shortcut with brewing gold wine directly.
Spices: the step before
Umami only upgrades silver to gold. Bronze Wine becomes silver at the Kitchen Table with 1 Spices instead, after Transmutation I.
Spices is another alchemy formula, 2 green and 2 blue.
Buying it
The Alchemist stocks 10 Umami from trader level 3 at a base 15 silver, and buys it back for about 11 silver 25 bronze.
Studying one pays +50 green and +10 blue tech points for 10 Science.
