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 only two places where brewing can be done, fermenting vats, one in eastern Keldagrim on the 1^st floor^[UK]2^nd floor^[US] of the Laughing Miner Pub and the other in Port Phasmatys underneath the The Green Ghost pub.

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 5% to 36% (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 Blandebir 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.

Fermentation

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, Tuesday 16 August 2022 is Day 1. (Note: This is usually today, but does not always update immediately when the date changes. Refresh the page to force it to update.)

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, it must be drained from the vat then from the barrel. There is roughly a 20% chance for an ale to go bad.

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 is 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.

Mature brews

With normal brewing, a player can randomly make a full vat of matured ale, however a majority of the time it will complete as a non-matured ale. The chances of ale maturing naturally is 5%, but adding the stuff increases this chance to 36%. Cider is the only brew that the stuff is not used for, it must always become mature naturally. Mature ales provide stronger boosts, heal more, and provide larger deboosts. The stuff is purchasable from Honest Jimmy for 50 pieces of eight, a reward from the Trouble Brewing minigame. If attempting to make mature ales, it is highly recommended using the stuff. It must be added right after the barley malt is added, it is not possible to put it in afterwards.

Note: "The Stuff" is not required to make a mature ale, it simply increases the chances that it does mature.

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 is 10,240 minutes or 1 week. This will depend on when you start the fermentation process during the current cycle.

Types of brews

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