Quality retention upgrade

🌟 **Make Stardew Valley’s processing machines smarter! **

Module introduction

I've long wanted a game that would allow you to retain the quality of the product, but not be too overpowering and require a certain amount of effort to get each improvement, which is why I made this mod.

🛠️ Features

This mod adds an upgrade system to the original machine, including:

  • 🍷 Brewing barrel
  • 🫙 Pickle Jar
  • 🌞 Dehydrator
  • 🐟 Fish smoker

⚙️ Upgrade system

Each machine has four upgrades (except the fish smoker, which only has two):

Iron upgrade

  • Product quality is one level lower than the inserted item
  • Iridium quality fruits → Gold quality products
  • Processing time is not affected

Gold Upgrade

  • Copy the quality of inserted items
  • Small chance of getting additional products
  • Processing time ×1.2

Iridium upgrade

  • Probability to improve product quality by 1 level
  • 50% chance to get additional products
  • Processing time ×1.35

Radioactive Upgrade

  • Always double product
  • Low probability of getting additional products
  • Higher probability of improving quality
  • Iridium quality items have an extra chance of getting more products
  • Processing time ×1.5

🍯 Special adjustments

To keep the game balanced, some machines have special adjustments:

  • The price of mead in brewing barrels will increase based on flavored honey
  • Adjusted production times to avoid imbalance

🔗 Compatibility

✅ Fully compatible with the original game

✅ Specially compatible with the following modules:

  • Visit Mount Vapius
  • Ancient Crops
  • Vanilla Plus Professions
  • Stardew Valley Expanded (SVE)

For SVE, the mod adds a new product inspired by Artisanal Honey Mead - a mead variant made using honey jars that isn't terribly expensive but has some interesting benefits.

Install & use Install: SMAPI mod (Stardew Valley standard)

  1. Install SMAPI first (Stardew Valley's mod loader): download it from smapi.io, run 'install on Windows.bat' and pick your game folder.
  2. Unzip the archive from playbuff and find the folder that contains manifest.json — that folder is the mod.
  3. Copy that whole folder into Stardew Valley/Mods/.
  4. Launch the game through SMAPI (run StardewModdingAPI.exe or set it as the launch option). The console before the title screen lists each mod's load result.

Cheat-style tools may not need SMAPI — unzip and run them as the readme describes. Back up your save before editing it; SMAPI lists failed mods in its console.
