Aeration System

OK, in my ever growing goal to slowly add things here and there and expand my brewing experience and quality, I am now ready to dive into the world of making sure I am providing plenty of aeration.

To date I am doing the whole forceful pours, topping off with as much splashing etc as I can get, at times even transferring wort back and forth from kettle to fermenter a few times. BUT now I want to instead get a pump and do it with a pump and air stone

I think I know the answer to this, but is it as easy as getting a fish tank pump and proper tubing and an air stone from somewhere? I see NB sells a kit, but I also saw comments that for about $10 I could of put the same thing together myself.

I think the answer is YES - but is it really just that simple? any things I need to think about, like how big exactly of a pump? any things about the stone? certain types?

follow up question - is the aquarium pump good enough, or of I am going to do this, should I be stepping up to an oxygen kit (which I think means you get actual canisters of oxygen and hook it up to something like this?)

http://www.northernbrewer.com/shop/brew ... n-kit.html

is the oxygen kit that much better? especially if I got a larger aquarium pump? I don’t want to spend money I don’t need to, but I am also ok with bying what I need if I am goig to buy anything at all.

I forget where, but I saw a study that demonstrated that an air pump is no more effective than vigorously shaking a carboy. The maximum achievable level of dissolved oxygen is the same for both methods (best case: ~8 ppm), because you’re using “air” which is ~21% oxygen. I believe 8-10ppm is the recommended range depending on the wort. The disadvantages of a pump are that you have to run it for a long time and it introduces yet another opportunity for contaminating your wort (two factors: sanitation of the equipment and you’re pumping air from the room, which is full of wild yeast and other potential contaminants), but a pump is obviously easier on your back.

With a simple oxygen system and a tank from Home Depot, you can get a five gallon batch into the recommended range with a 60 second application of pure oxygen. Worth the investment IMO. Shop around to find the best deal.

ya I was wondering about the whole 20 + minutes of open fermenter and it seemed like one more chance for something to float over or into the beer.

Like I said, unless it is outragously expensive, if I am going to bother with it I would want to do it right.

I will look at the home depot/lowes route. ball park, anyone know what that would run? $20? $40? more?

I’m in a similar boat. I’d spend the extra few bucks and upgrade to pure O2 with a regulator and stone. Max 60 seconds with pure O2 for most ales. I’ve been buying 02 cylinders recently and using my neighbors regulator and stone. Prior to this, I was shaking, which research proves isn’t really that effective.

spend the 50 bucks and get an oxygen kit, you won’t be dissapointed

Sorry, my post was slightly unclear with regard to what you can get from Home Depot. You can get the O2 canisters, but I don’t believe they carry the other components.

I highly recommend this route: http://www.williamsbrewing.com/WILLIAMS … 9C106.aspx

NB’s O2 kit is fine too, but the rigid wand is a lot easier to use than a hose IMO. A lot.

The hose is just as easy to use, Storage, cleaning, and sanitizing is the main thing to think about between the hose and stainless IMO

this is perfect, thanks. $50 or so on this and what looks like $10/canister at home depot for the oxygen looks like the route, both with ease and effectiveness.

and… someone (me that is) has both a birthday and fathers day coming up and a whole batch of people looking for ideas for me.

I will say as much as my wife doesn’t like howmuch time this hobby takes up, she does like the fact it always provides her some idea for a gift she can give me or tell my family. ever expanding hobby

seriously, as always thanks for all of this. helps tons

I disagree. In my experience the hose would tend to curl up in the carboy and it was a challenge to get it to the bottom. Basically the same price for a kit with a rigid stainless wand is a no-brainer IMO. :wink:

Now you need to find a style of beer that she really likes, or maybe a wine, and keep that on hand for her to enjoy. :wink:

I have never had that issue, its a hose you just push it to the bottom. I’ve used both and they both have up and downs. I really hate how you cant take the stone off the wand.

the disposable tank are 6 or 7 bucks

Yes I did a very fast search on Lowes and it was $9.99, but that was online and in stores may be a bit cheaper or a few bucks lower at home depot. still not that much.

So sounds like I need to:

  1. decide on the hose type option from NB or the SS Wand from williams brewing
  2. buy a tank from home depot/lowes

I am liking this route much more than the aquarium pump route.

It’s a great upgrade. You will see a difference in fermentation on your first use.
When you go to Lowes or Ace or Homedepot they are sometimes hard to find, never a ton in stock and tucked away usually by welding supplies

ok, maybe one more completely stupid question.

once I use up the whole tank, do i return it to them for a fill up? dispose somewhere special? just toss in the trash (I am thinking NO to that last one).

they do not fill, they are disposable tanks.
SOme throw them away, some bring to recycling places that take them, etc…

Why do you need to take the stone off the wand? It should not need to be replaced.

just for that reason to replace it if something happens to it. I also like to boil mine before and after use so it doesn’t clog. That’s a pain with the big wand

Something happening to it sounds like user error to me. :stuck_out_tongue:

Easy to boil. I put it in a 2l flask.
