If you've ever looked at a jug of apple juice and wondered how hard it would be to turn it into hard cider, the answer is: not very. Juice already has the sugar. You add yeast, give the gas somewhere to go, and wait. That's it.
My no equipment cider video got way more attention than I expected, so here's the full version. Same idea, with a few extra steps that make your cider cleaner and more consistent.
What Is Hard Cider?
Hard cider is fermented apple juice. Yeast eat the sugar in the juice and turn it into alcohol and CO2.
For reference, federal tax law defines hard cider as a wine made mostly from apples or pears with less than 8.5% alcohol by volume (26 U.S.C. § 5041). Plain apple juice on its own ferments to about 5%, so you're well inside that.

What Equipment Do You Need?
Honestly, not much. In the video I fermented right in the juice bottle, and some people just use a balloon or a loose cap. It works.
If you want more control, here's the basic setup for a one gallon batch: a fermenter with an airlock and stopper (the airlock lets CO2 out without letting air in), a hydrometer to measure sugar and alcohol, a siphon for moving the cider off the sediment, and a no rinse sanitizer. You can put this together from any homebrew shop. If you'd rather have it all in one box, my Glass Mead Making Starter Kit has the gear plus the included essential ingredients (yeast, nutrient, and stabilizers). It's there if you want the convenience. You don't need it to make good cider.
The Ingredients
You need about a gallon of apple juice and yeast. The juice is the part people get wrong. Check the label: it should be juice that's pasteurized (heat treated), with no preservatives like potassium sorbate or sodium benzoate. Those are there to stop yeast from growing, which is exactly what you don't want (NDSU Extension). Added vitamin C (ascorbic acid) is fine.
For yeast, I use K1-V1116, the same yeast in my kits. Lallemand lists it for cider and it handles tough conditions well (Lallemand). That said, any brewing yeast will work. What I'd skip is bread yeast. It ferments, but the results are a lot worse.
I also add a yeast nutrient like Fermaid O. Happy yeast means fewer weird smells.
Want a Stronger Cider? Make a Cyser
Here's where cider meets mead. A cyser is apple juice fermented with honey. More sugar going in means more alcohol coming out, and the honey adds a floral note that plain cider doesn't have. Technically a cyser counts as a mead, but unless you're entering a competition, don't get too hung up on the name.
Stir the honey into some of the juice until it dissolves before it goes in the fermenter, and don't heat it. Heat drives off the aromas you're paying for. How much honey is up to you, and your hydrometer will tell you how strong it's headed. Any good raw honey works. My go to is wildflower, and I sell a raw unfiltered wildflower honey if you want the one I use.

Step 1: Sanitize Everything
Poor sanitation is the number one reason batches go bad. Mix your sanitizer, wipe down your workspace and hands, and fully submerge anything that touches the cider. Expect it to foam. Yes, it's really that simple.
Step 2: Fill Your Fermenter
Pour the juice into your fermenter and leave some headspace at the top so foam doesn't push into the airlock.
Step 3: Take a Gravity Reading
Before the yeast goes in, take a reading with your hydrometer. This is your starting gravity, basically a measure of how much sugar is in the juice. You'll need it later to figure out your alcohol. If you've never used one, I walk through it in How to Use a Hydrometer.
Step 4: Pitch Your Yeast and Nutrient
"Pitching" just means adding the yeast. I like to rehydrate first: 25 mL of water at 95 to 98.6°F, stir in the yeast, and let it sit for 20 minutes. Small bubbles and a bready smell mean it's alive. Add it to the juice along with your nutrient, give it a good stir (yeast like a little oxygen at the start), then put the stopper and airlock on.
Step 5: Let It Ferment
Keep it at room temperature and out of direct sunlight. How long it takes depends on your starting gravity, meaning how much sugar the yeast have to work through. Fermentation can finish in as little as a week. A cyser with extra honey has more sugar to get through and will usually take longer.
Don't trust the airlock to tell you it's done. I take a reading about once a week, and when the gravity is unchanged for two consecutive readings, fermentation is finished. Once you have your final number, here's the math: ABV equals starting gravity minus final gravity, times 131.25.
Step 6: Stabilize Before You Sweeten
Cider usually ferments bone dry. If you like it that way, skip ahead. If you want it sweeter, you have to stabilize first, or the new sugar will restart fermentation inside sealed bottles. That's how bottles explode.
For one gallon, add one crushed campden tablet (about 0.5 grams), wait 24 hours, then add 1/2 tsp of potassium sorbate (about 1.5 grams). Wait another 24 hours and you're ready to sweeten with honey, sugar, or more juice, a little at a time, tasting as you go. The full reasoning is in How to Stabilize Mead, and it works the same for cider. Both stabilizers come in my kits, and you can also find them at any homebrew store.
Step 7: Bottle It
Siphon the cider off the sediment into sanitized bottles, keeping the siphon above the gunk at the bottom and avoiding splashing. Leave an inch or two of headspace and cap them right away. Only bottle once fermentation is finished.
People Also Ask...
Can I make hard cider without yeast? Technically, wild yeast on fresh pressed cider can ferment it, but it's unpredictable. Pasteurized juice has had most of that wild yeast killed off, so add your own.
Can I use apple cider from the store instead of juice? Yes, as long as it has no preservatives.
Is it legal to make hard cider at home? Yes. In the US, adults can make wine (hard cider included) at home for personal and family use under 26 U.S.C. § 5042, but you can't sell it. States can add their own rules, so check yours.
Final Thoughts
Once a plain gallon makes sense, play with it: try a cyser, or add a cinnamon stick after fermentation for a fall version. Use whatever gear you have, and if you'd rather grab everything in one place, my kits are there for that. Let people know how strong it is when you share it, and enjoy it responsibly if you're of legal drinking age. Cheers!
