Buy RS3 Ale yeast
Ale yeast is a key brewing ingredient in RuneScape 3. It comes in a pot and is used with the Cooking skill. It is the last ingredient you add to a fermenting vat. Adding it starts the fermenting process, which can take two to four days.
Ale yeast is needed to brew many ales and drinks. These include Asgarnian ale, Dwarven stout, Greenman's ale, Wizard's mind bomb, Dragon bitter, Chef's delight, Slayer's respite, Axeman's folly, Moonlight mead, Pigswill, Cider, and more. Many of these drinks boost skills like Mining, Smithing, Herblore, Magic, Cooking, and Slayer. That makes ale yeast useful for players who want to train faster or reach skill goals.
In the game, ale yeast can be bought from brewing assistants like Blandebir in Keldagrim, Malt in Wendlewick, or Metarialus in Port Phasmatys. You need an empty pot in your backpack to hold the yeast.
Ale yeast is tradeable and noteable, so it is easy to stock up for big brewing sessions. It weighs 2.834 kg and can also be disassembled. If you plan to brew ales in RS3, ale yeast is an item you cannot skip.
