So I bought my equipment kit and a extract kit today from a local homebrew store, however it seems that their kit is low on instructions. I would call the store, but the guy was kind seemed pretty disinterested, so if I can avoid calling there I would prefer to.
It came with 2 cans of malt extract, and on the back of the can it says "Mix can (4 lbs) with 5 gallons of water"
However my concern is that I have 2 cans of the malt extract, should I mix BOTH cans with 5 gallons of water? Plus I was under the impression you didn't boil that much water for the wort.
What should I be doing here? I would hate to brew this up, and then in 2 weeks find my beer tastes like pee.
First off, John Palmer's How to Brew is the place to look for full instructions. That said, here's a checklist I used doing a simple extract partial boil:
Part 1: Preparing the yeast starter
1. 3 days before brew day, mix 200g of DME with 2 liters of water in a sanitized jug (1 gallon or so is fine). Add the yeast to this. Cover the lid loosely with sanitized aluminum foil. Let it sit at 70F (or slightly warmer; below 80 is fine). Swirl it around gently whenever you happen to walk by it (a couple times a day or so)
2. The night before brewing, move this jug into the refrigerator and let it sit undisturbed. By morning, the yeast should have settled out on the bottom of the jug.
3. Gently pour off all but 1/2 inch or so of the liquid on top of the yeast.
Part 2: Brew day
1. Put 3 gallons of water in a pot; bring to boil.
2. While that's going, put 2 gallons of clean water (either boiled or distilled water straight out of the jugs) into your sanitized primary fermentor. Cover it up (sanitize the cover!) Shake it up a lot to aerate it. Leave covered
3. Once you're at boiling, turn off the burner. Add 1 can of malt extract. Mix it
thoroughly. Unmixed extract can settle on the bottom of the pot, burning or creating off flavors.
4. Bring back to a boil and wait for the hot break.
5. Start your 60 minute timer now. Add the hops on the schedule they were given to you (if some are added at 60 minutes, they go now).
6. At 15 minutes, turn off the burner and mix in the rest of the extract. Turn back on and count down the last 15 minutes (add any hops at 15 minutes or later after you turn the burner back on).
7. With 5 minutes to go, prepare an ice water bath for cooling.
8. When time's up, put the pot in the ice water and cool to 75F.
9. Pour vigorously into the fermentor (you're trying to mix air in with the wort) while keeping out as much break/hops as possible. You need 5 gallons at this point, and there could have been some boil off. Use sanitary water (boiled or distilled water straight from a jug) to top it up to 5 gallons.
10. Put the sanitized top back on the fermentor, and shake it for 10 minutes to aerate
11. Using a sanitized hydrometer, take a gravity reading.
12. Add the yeast (swirl the liquid in the starter jug around to mix up with the yeast and pour it all in)
13. Put the top on and shake again to blend the yeast
14. Put the airlock on and put it somewhere that's about 5F below the right temperature for your yeast (the fermentation will generate some heat to bring that temperature up).
