Buy RS3 Calquat keg
The Calquat keg is a handy item for brewing in RuneScape 3. It is made by using a knife on a calquat fruit. The fruit is sliced and hollowed out to form the keg. Calquat fruit can be grown by players with level 72 Farming.
This keg is used to collect full batches of ale. Each keg holds the same amount as 4 beer glasses of ale or cider, which is 4 doses. Players can fill up to 2 kegs from one batch of ale by using them on the barrel attached to the fermenting vat. Ale that is already in beer glasses cannot go into a keg. Pouring from a keg into glasses is possible, but it may cause a loss, so it is not a good idea.
The keg is light at only 0.028 kg. It is tradeable and noteable, and it stacks when noted. It can also be disassembled. Doing so gives mostly Simple parts, with a small chance of Variable components. Bob Barter can combine 3-dose, 2-dose, and 1-dose portions from your inventory into full 4-dose Calquat kegs.
