Brewing

Brewing is part of the Cooking skill that allows players to create alcoholic drinks, specifically ales and cider by fermenting ingredients. They all provide temporary skill boosts for varying skills as well as lowering some combination of Attack, Strength, and Defence. Every ale and cider has a mature form which increases both the negative and positive boosts.

There are three fermenting vats in Gielinor. One is located in eastern Keldagrim, on the 1^st floor^[UK]2^nd floor^[US] of the Laughing Miner Pub. The other vats are located in Port Phasmatys underneath the The Green Ghost pub and in the the Moonrise Brewery and Winery on Aldarin island in Varlamore.

Brewing was released on 11 July 2005 alongside the Farming skill as part of the Farming update.

Brewing process

Ales

The main ingredients for ales are: 2 bucket of water, 2 barley malt, 1 ale yeast, and optionally: 1 the stuff

Steps
1. Use 2 bucket of water on the fermenting vat
2. Use 2 barley malt on the fermenting vat
3. Optional: Use 1 the stuff on the fermenting vat, increasing the chance to mature the ale from ~4.7% to 64% (the stuff will be consumed)
4. Use the ingredients specific to the brew type you want to make
5. Use 1 ale yeast on the fermenting vat
6. Wait for 3 x 640 minute cycles (with the stuff added, between 3 x 640 and 16 x 640 minutes)
7. Use the valve to drain the completed ale into the barrel
8. Use 8 beer glasses or 2 calquat kegs on the barrel full of the completed ale

Cider

The main ingredients for cider are: 4 buckets of apple mush, 1 ale yeast

Steps
1. Use 4 buckets of apple mush on the fermenting vat
2. Use 1 ale yeast on the fermenting vat
3. Wait for 3 x 640 minute cycles
4. Use the valve to drain the completed ale into the barrel
5. Use 8 beer glasses or 2 calquat kegs on the barrel full of the completed cider

Ingredient notes

• Barley malt can be made by using barley on a range.
• Ale yeast can be purchased from either Blandebir or Lucrezia for 25 coins or Metarialus for 5 ectotokens. You must have an empty pot in your inventory for them to give you ale yeast.
• The stuff can only be purchased from Honest Jimmy with 50 pieces of eight from playing the Trouble Brewing minigame.
• Apple mush is made with an apple press, there is one next to each fermenting vat. Four cooking apples and a bucket are required.

Brewing mechanics

Fermentation time

Brewing relies on the same farming cycles as hardwood trees, redwood trees, and anima. There are three stages that each brew must go through in order to complete, advancing to the next stage at the next growth tick. Brewing ticks only occur every 640 minutes. However, there is an offset for farming ticks that is different for each player and persists through logins. To determine this offset, note the time when a hardwood, redwood, or anima patch grows one stage, or when a brew completes and compare with the closest time on the table below. Apply the time difference to every time in the table. For example, if a brew completes at 10:18 AM on Day 1, subtract 22 minutes from each time listed.

Cycle length	Main crops	Base growth times(GMT)
640 minutes	Hardwood, Redwood, Anima, Brews	Day 1: 12:00 AM, 10:40 AM, 9:20 PM Day 2: 8:00 AM, 6:40 PM Day 3: 5:20 AM, 4:00 PM Day 4: 2:40 AM, 1:20 PM

In the table above, Friday 31 January 2025 is Day 4. (Note: This is usually today, but does not always update immediately when the date changes. Refresh the page to force it to update.) The next stage will occur in approximately 0 hours and 47 minutes (refresh). When (after refreshing) this timer indicates 10 hours and 40 minutes, this signifies a Farming tick just occurred (due to the farming tick varying between accounts, it is recommended to wait another 15 minutes).

The first stage begins immediately after adding ale yeast. The second stage will occur on the next growth tick where it is possible for the still fermenting brew to become mature. The final stage has three possible outcomes: a completed normal ale, a mature ale, or a bad ale. Bad ales are green and useless, and must be drained from the vat and then the barrel.

Standard times to complete when not using the stuff, is at minimum 1,281 minutes, about 21 hours and 20 minutes, or 1 minute past 3 growth ticks. At maximum it will be 1,920 minutes or 32 hours, which is the full 3 growth cycles. This depends on when you start the fermentation process during the current cycle. When using the stuff, the standard times to complete is at minimum 1,281 minutes, about 21 hours and 20 minutes, or 1 minute past 3 growth ticks. At maximum it is 10,240 minutes or 1 week.

Brewing outcomes

There are three possible outcomes when brewing a batch of ale: the mixture can either go bad, ferment into a regular batch of ale, or ferment into a batch of matured ale. The chances of a vat of ale maturing are dependent on whether players add in "the stuff" or not; the chances of ale maturing naturally is 5%, whilst adding "the stuff" increases this chance to 64%. The odds of the ale going bad will always be 12.5%, regardless of whether "the stuff" has been added or not. Lastly, the player's Cooking level does not influence the outcome of the brewing process in any way.

Mature ales provide stronger effects and heal more, and using "the stuff" is highly recommended if attempting to brew mature ales. It must be added right after the barley malt is added, as it is not possible to put it in afterwards. In addition, "the stuff" cannot be added to a vat of cider, and so matured cider must always be brewed naturally.

When a batch of ale is complete, using "turn valve" will automatically transfer the finished ale to the barrel. The examine text will say "The vat is filled with [beer name]" when the brewing process is complete. If you attempt to turn the valve before the brewing is complete the contents of the vat will be emptied and lost.

Without "the stuff"

When no "stuff" is added to the mixture, players can expect the following rates:

Outcome		Chance
	Mature ale	6/128
	Regular ale	106/128
	Bad ale	16/128

With "the stuff"

When "the stuff" is added to the mixture, the odds are adjusted to the following:

Outcome		Chance
	Mature ale	82/128
	Regular ale	30/128
	Bad ale	16/128

Types of ale

All brews must be collected from the barrel with 8 beer glasses or 2 calquat kegs.
