Buy OSRS Apple mush
Apple mush is a members item in Old School RuneScape used for brewing cider. It comes in a bucket and is made by crushing four cooking apples in an apple press. Making it needs level 14 Cooking.
Apple mush is the main ingredient for cider and mature cider. To brew a batch, put four apple mush and one ale yeast into a fermenting vat. This makes eight beer glasses of cider or fills two calquat kegs. Each brew gives 182 Cooking XP. A full brew needs 16 cooking apples in total, so buying apple mush saves you the work of picking and crushing apples yourself.
Apple presses can be found in eastern Keldagrim, Port Phasmatys, the apple orchard outside the Tree Gnome Stronghold, the Moonrise Brewery on Aldarin, and the Burgh de Rott Myreque Hideout after the Blood moon rises quest.
Apple mush is tradeable and noteable, but it does not stack. It weighs 1.1 kg per bucket. If you want to train Cooking through brewing or just need cider, apple mush is the item to have.
