Salut ! A few comments regarding your comments : - Obviously I could have bought a home-brewing kit either in a brewer's shop or online as they are pretty affordable and widely available. But that is not the point of this video. It's here to introduce all of us to a world I did not even know existed and to entertain you along the way. Beer world is fascinating. - The initial plan with yeast was to use and grow bottled conditioned beer leftovers as our own yeast strain. It obviously would have been better than using bread yeast. But after finding some, which was a big pain already that thing isn't widely available, real hard, we couldn't get any reliable success growing it. - There is indeed no enzymatic action in our mash, but our malt extract is already fermentable and we don't need the sugars from the wheat and oats - just the starch for body, plus the flavour and proteins for head retention. - (I'll update this comment if needed)

Milton for sterilising (in the baby aisle... tablets or liquid)... use it for my brewing. For yeast, buy one bottle of traditional “bottle conditioned” beer... There are loads now in supermarkets... drink it, but leave an inch in the bottom... add sugar and water and leave in a warm place to grow... creating a “yeast starter” of professional quality brewers yeast ready to pitch into your wort. Great video as ever, Alex. :-)

The cashier after seeing what they bought: ”Oh my, they’re going to throughoutly clean their home and then bake something delicious to their sweethearts! What a shame my sweetheart only thinks about beer...” •sigh•

After this please make proper beer brewing series with home made equipment. Please

10:37 Alex: Do you think it can work? You can literally read the other guy's thoughts... _I have no idea what you just said, but I'll go with it._ "YES".

The part where you explain the cups being stacked to prevent air getting in was gold 😂😂😂

I enjoy the ad progress bar at the bottom of the video.

Dude: Nobody is doing grapefruit in beer Schöfferhofer: Hold my Weizen.

So happy I’m not the only one geeking out over his Kaweco sport fountain pen.

Nobody: Alex: "I'm just checking if this (bleach) have any flavor agent"

I can't help but consider "A frenchmen goes to England to brew beer" to be the beginning of a joke. Note: You're not supposed to cut beer with a knife.

My grandfather homebrewed, my Dad homebrewed, both my brother and I homebrewed … great vid and a nice change from the 'normal' cooking vidoes. Cheers, chappie!

"There's no way you can find these ingredients in your supermarket" *laughs in Oregon*

Today's episode: Alex in British accent mode

You could “harvest” yeast from a bottle conditioned beer you pickup at the grocery store. Then you could actually have beer yeast still.

Ok I'm super excited about this and spreading it like bitter!

Craft brewer here. So the main thing that caused the infection was adding unsanitary liquid to the wort after your boil to bring down the temperature. That water though it came from a bottle was not sterile in the brewers sense. Use isopropyl alchahol and use it everywhere. Pasturize your utensils hold at 180F for about at least 5 minutes. Also blooming the yeast isnt necessary just toss it in. Its sanitary. You have to keep it 100% sterile until the yeast can take hold. As a brewer. Yes you get a nice gentle kick to the nutz even on a big system haha.

you can find fresh yeast in the uk by the butter...😂

So you're making prison hooch?

I'm so glad that the boys from the Craft Beer Channel look sceptical, they have their work cut out keeping you in line. I've been dreading this series since you first suggested making beer, it was never going to be normal. It's now like a road crash I want to look away but I can't and I can't unsee any of this.

3:19 Was not expecting to see castle lager included in 1 of your videos 😀.

I don't know if video length is 13 37 on purpose but the bleach thumbnail is a masterpiece

I don't know where you get the alcohol Torrance from bakers yeast. It is commonly used for sugar washes to distill, I often get 14% abv,

10:23 his face is priceless!!

10:24. Ahh, Mechanical Engineering. His expression isn’t confusion, it’s awe. Well done, Alex.

In Finland you can buy beer brewing kits from supermarkets and wine kits too !

If your cup-based airlock contraption doesn't work, you can simplify by using a balloon. Just stretch the the mouth of the balloon over the top of the jug and put a little pin hole in the top of the balloon. As the wort ferments, the gas will inflate the balloon a bit, but can escape... and the balloon will flop back down and prevent air from getting in. (And if the balloon isn't big enough to stretch over the top of the jug, then there are other, similar latex-based product that will work, and that are often sold at supermarkets. Just be sure to wash off any lube before using one...)

As a brewer, I'm both mortified and super curious about the results! Looking forward to the next video Alex!

In America we sell beer making kits in super markets. Even the raw ingredients to make them. Yes yeast and hops to.

"Do you thing it can work?" 10:38 When your face says "yes" but your brain is shouting: "Absolutely fucking not".

The reinheitsgebot is cringing at this video. Love brewing beer at home. This is very clever, great video.

I simply _cannot_ wait for the next episode. So exited!!!!

Dude, can you read my mind? I'be been wanting to make my own beer for the last week now!😍

Gotta love how this french man in england is trying to find a way that ANYONE can make beer from the grocery store, only to get a bunch or americans saying "just buy unpasteurised beer from the grocery store as your yeast source", not realising that they are one of the few countries that sell their alcohol next to their baby formula XD... also with the airlock you just need a few bendy straws, join them together to make a long one, stick one end through a hole in the lid and the other end in a glass or water (or vodka)

Also London water is actually good for brewing once you correct for oh, according to that book I mentions on water. The cheap way to make a airlock is a balloon with a pin hole in it placed on thw bottles nossle. Be careful for the fermentation to expand during process. Leave some space in the bottle or put it in a container to catch it.

Makes me proud to see Castle lager represent

Next video, Alex makes diy cocaine with supermarket ingredients in Columbia.

The head nod killed me. 🤣🤣🤣🤣

The only thing missing is gelatin to reduce cloudiness

Also insider tip - if you wanted Fresh Yeast - if you go to a larger store that makes its bread from scratch if you ask nicely at the counter they can provide you with a small amount of their yeast for free ;) Dunno if it does any thing different or better/worse in this scenario compared to dried but its something

Some bloody proper banter in this video.

Fermenting valves suck. I once made an impromptu replacement with stretch foil and rubber bands and then I never went back. As long as the vessel has a lip for the rubber bands to hold onto and they are put on tight, they keep the fruitflies out and the oxygen as well, since there's a slight overpressure from the fermentation. Plus, there is no sealing liquid that can dry out or contaminate your ferment :)

The yeast that is used for bread is only slightly different from the one for beer. Its actually Saccharomyces cerevisiae. The name cerevisiae comes from "beer". And one more thing. The malt is used for flavour and for the enzymes. But as you may know is that the yeast can produce its own encymes if you let it ferment long enough. Also you could may get some whole grains from the store and make your own malt. It's really easy to do. You have to water the grains and let them sprout for some days and then you can stop the sprouting by drying them in an ofen. For more Flavour you can even roast some of the malt.

Here's how to make a suitable yeast for brewing. Get some really acidic apples. Bramleys in the UK. Turn them into juice. Put it in your fermenting vessel with an airlock and leave them to ferment. It may take 2 or 3 weeks to get started. When the fermentation has finished use a little of the sediment to make your yeast starter. The acidity and alcohol will have killed all the non-sachromyces and alcohol intolerant strains.

02:04 He hums “Little Green Bag” by the Dutch 60’s band “George Baker Selection” Little green bags of hop? Let’s go to the Hop!

This seems like heavy weather, in Australia you can buy beer making kits in the supermarket.

Solving the yeast problem: Buy a beer and culture the remaining yeast in the bottle to get the quantity needed for your beer. Simple ... and they do sell beer in the supermarket.

That’s fantastic you guys just made Gruit beer 👍🏻love it nice video

I am liking this! I have done similar things. Of course this is already done and we are being treated to the edited video, but two things I would suggest is to add raisins to the mix if you cannot find malt. Fresh bread will supply the yeast. There are live yeasts in some beers that you could cultivate as well. The airlock could be replaced with a plastic tube from a slingshot or replaced altogether by a heavy tapered stopper that settles back into place after the CO2 escapes. My mother used really large ballons snapped over the mouth of the jug.

Me:walks out my usual supermarket with a box of wheat cereal Cashier: what you got there? Me:I’m just brewing some beer Cashier:stares at me judgingly*

I would love the recipe for this!!!

You can make up to 14-15 percent alcohol with normal bakers yeast, I have made very good and dry “wines” with that. 3 percent is just plain wrong. Even without adding anything the wild yeast on air or a grapes skin can make decent alcoholic wines

Looks fun! Can’t wait for next episode!

Super cool. This is like a mega fancy (beer) version of slapping champagne yeast into a big jug of apple cider and letting it sit for a moth.

these guys are hilarious, you guys bounce ideas off each other and the chemistry is so good, I would love more collabs in the future

Watching him trying to explain how to build an air lock, and the scrappy homebrewers are all thinking.... "a balloon or condom with a pinhole in it would work fine."

The simplest way to make an air lock is to submerge a flexible plastic tube into a large container of water. Also you could have used Malt-O-Meal as a source of malted barley. I'm not sure if they have that in the UK but it's in every store in the US.

I am a food nerd in culinary school and I absolutely love this channel. Thank you for providing such quality videos Alex! 👌🤙

J'ai toujours admiré cette décontraction dans l'accentuation française forcée de la langue anglaise.

10:38 that's the face you make when you have no idea what was just said but you don't want to hear the explanation again.

Did you know that Sainsbury's you went into is the first supermarket in the UK to become listed. That means it's considered a historic building and we're no longer allowed to tear that monstrosity down. Pour one out for architecture.

I'm loving this series! A topic so close to my heart. Can't wait to see how it turns out. Good luck!

you can harvest and multiply brewer's yeast from a craft beer that's not pasteurized- Sierra Nevada pale ale is ok, and black's butte is another.

instead of a complicated yeast-lock with cups and straws, just use a rubber balloon with a tiny hole covering the bottle neck :) Thank you for making such cool, creative and inspiring videos! One af my alltime favorite youtube-channels :)

Great series idea

Sooo hyped to see how this beer will come out! Though for the containers I think most supermarkets sell the huge tanks for the water dispensers like in an office.

The filming style in the supermarket was well done and interesting. Loved the intro edits too. This 'beer' sounds interesting, looking forward to seeing how it turns out.

Well for the yeast, your better option would be to get some beers that is carbonated with live yeast on the bottle, with just a few beers and time it will start multiplying itself. Also for a waterlock, just some tubing from the fermenting bottle into a glass of water would work great.

This would be easy in the US: Whole Foods supermarkets generally carry all the brewing equipment from pots to coolers, ingredients and bottles.

Been brewing since I was 18. This is exciting :)

Using baking yeast should be fine as it is used in Sahti brewing (can also use wild yeast). Sahti is the traditional finnish style of beer. You should try making it sometime!

Alex, nice series.... excellent to revisit during lockdown! Please can you share the “recipe” or ratios.

Alex, I _really,_ _r e a l l y_ appreciate the progress bar for the ad read. Not quite as much as I app-reci-ate the unique cadence you francophones have when pronouncing certain words - but still, _a lot._ Thankyou.

I wonder what ink is in Alex' fountain pen. Logic dictates it's got to be a Noodler's, but he's French, so it might be something from Herbin or Waterman, too...

Pero is a coffee substitute drink made from malted barley, barley, chicory and rye. I wonder if you could use that in this recipe? It is found in the coffee section in many supermarkets.

Sure you can. I once brewed ginger beer with only ginger, sugar, water, and yeast. I boiled a random amount of ginger, added a random amount of sugar, poured it into an old 2L soda bottle, added some yeast i found at the back of my pantry, and let it ferment for like a week, opening it once every day to let the co2 escape. It tasted a bit harsh but I didn’t even get an upset stomach. People have been fermenting whatever they could find for thousands of years. It’s hard to mess it up. Life finds a way, bro. ☺️

Where are you going to get enzymes to digest starch from the cereals to ferentable sugars? Enzymes are the reason why brewers use malt instead of plain grain.

Fuck yeah I was craving for another episode based series like this!!! I just hope we don't have to wait too much to see the next episodes. :)

2:05 That's incredible! I was singing that song at that precise moment!

What if your local supermarket sells home brew kits?

Were you just humming, "Little Green Bag?"

Raisins! Raisins contain lots of alcohol reisistent yeasts, so that could have been the starter for yeast. Make a starter out of raisins in water and after a day or so you'll have a wild ferment for higher alcohol yeasts.

Just an FYI but I've picked up 7-8% from bread yeast with a hard cider. Sure, it won't reliably make that ABV since it's not designed for it but you can go much higher than the 3%. You can also go the route of harvesting yeast from unpasteurized beer already there in the store if you don't trust bread yeast or enjoy the flavors you get from it.

Sanstar and kombucha bottles because you can reuse them and if you over charge it you can laid off some of the pressure and then retighten the cap

This looks like fun!

3 of my favourites on YT making my favourite beverage - I press like!

Parlsey Alex. It has antiseptic bitter compounds just like hops. You can "train" your yeast. It will mutate and adapt to its environment. Bakers yeast will evolve into brewing yeast. Also, You could get a craft microbrew with sediment which contains cultures of brewers yeast.

Barley and the hops TV made the same project, and used sprouts to convert the starches.

I'm so keen to see how this pans out I really want to make my own beer to save money and hopefully to use healthier ingredients.

That seems like an incredibly complicated airlock. 4 layers of cling film and a rubber band will make a perfectly good seal. You can also put a straw between the cling film and the bottle neck to make venting gas easier. Alternatively, burp it when it starts to bulge. I've never had a brew go off when using this method. Some people use a balloon with a pin prick hole in the top, too. Never tried it myself, though.

You could’ve just used a balloon with a little hole poked in it for the airlock. If you wanted to you could’ve bought whole grain & malted it. And you could’ve basically made a sourdough starter for the yeast.

Right after the portion where you were explaining how you plan to make the valve, I got a commercial for Sprint cellular that opened with the line “isn’t it nice when you can keep things simple”?

So excited for this series!

"Doability" aka feasibility 😆Looking forward to the brewing process though.

You can also just run a hose or tube from the top of the fermenting vessel to a bowl of water.

"They have no idea what we're doing - buying bleach and porridge" Meanwhile in America, you're now on a government watchlist. XD Can't wait to see how this turns out.

for times when you don't have bubbly stuff (or you can't keep up with checking out if the water is still there): insert a tube (hose?) into the hole where the bubbly stuff should be, insert the other end of tube (hose?) into a bucket with water (make sure this end is always below water level).

cant wait for episode 2

Ask the bakery department in your local supermarket for fresh yeast.

Alex, wouldn’t it be less expensive to buy a pint of Guinness at a local pub?
