OxyWand Oxygenation Kit

Frequently cited benefits of proper wort aeration are avoiding these fermentation problems: 1. Long lag time from yeast pitch to start of fermentation, 2. Stuck or incomplete fermentation, or 3. Excessive ester production affecting flavor. What can be overlooked in these explanations is that not all fermentations are created equal. The more “challenging” your fermentation, the more prone to these problems you’ll be. Fermentations for yeast are more challenging if you’re fermenting cold, if you’re using re-pitched versus fresh yeast, the age of your yeast is on the older side, or you have a higher gravity wort. In these cases, adding oxygen can make a difference.

To evaluate this, I brewed a few different batches of beer to test for the presence of these potential issues while evaluating three different aeration techniques. The first technique was a simple process I’ve used for years. While transferring the wort from kettle to fermentor, I let it pass through a strainer and splash down into the fermentor. It’s passive and easy, which is why this is my standard process.

Hands on Review: MoreBeer’s Fermentap Magnetic Stir Plate

MoreBeer’s Fermentap Stir Plate along with a 3,000 mL Erlenmeyer Flask

This review is by Homebrew Finds Contributor Brad Probert.  Brad is an engineer, expert homebrewer and experienced reviewer.  Grab a link to Brad’s website at the end of this review.

About Stir Plates and Erlenmeyer Flasks

Stir plates are pretty simple machines. There’s a small electric motor in a housing with a flat surface for you to set your vessel on that has wort needing to be stirred. When the motor spins, a magnetic field is created as a by-product of the electric motor. This is used together with a small plastic-coated magnet that looks like a small capsule, called a stir bar. If your flask is filled with wort, the stir bar spins around at the speed of the electric motor in the stir plate and creates turbulence in your wort. It creates a vortex like an underwater tornado as the spinning motion pulls wort down towards it and then flings it away when it contacts the stir bar.

This underwater tornado is the key to the stir plate’s success in preparing starters. This stir plate motion has two functions: 1) Keeping the yeast constantly in suspense and not letting them settle out, 2) The constant circulation of wort helps expose all of the wort to the surface where it can interact with incoming oxygen and purge CO2 developed by the yeast’s fermentation processes. There have been experiments done that show you can more than double the amount of yeast cell growth in a starter made with a stir plate versus a starter that doesn’t.

The vessel of choice for starters made on a stir plate is the Erlenmeyer flask (named after a German chemist who invented it in 1860). Its wide, flat base make it stable to sit on your brew table or on the stir plate without concerns of it getting bumped and tipping over. And very importantly, its flat bottom allows your stir bar to rest in the center and spin. A glass growler with its domed-in bottom, will not keep the magnet centered and then won’t work to stir the wort.

When looking for Erlenmeyer flasks, you want to make sure you get one made with Borosilicate glass. It is less sensitive to growth/shrinkage with temperature extremes, meaning it can go through thermal shock with less risk of breaking. But there’s an important caution here. Borosilicate is not recommended for direct heating. I heard from a Customer Service Manager at a homebrew shop about the horrific pictures he got from someone that was carrying their boiling starter wort from stove to sink when the glass bottom broke and showered his [sandaled] foot with glass and 200 degree wort. So boil in a separate vessel before pouring into your flask, or let it sit and cool a bit before you move to the cooling stage.

FOUR x Sanitary Air Filters [Oxygenation, Aeration, Siphon Starting] – $8.27, $2.07 each w/coupon

Sanitary Air Filter,Ferroday 4Pcs Water Fittings for Beer Brew Keg and Homebrew (4pcs of Pack)

Sanitary Air Filter,Ferroday 4Pcs Water Fittings for Beer Brew Keg and Homebrew (4pcs of Pack)


From the product description, check product page for current description, price and availability:

  • 5/16″ barbed connections
  • Filters down to 0.023 micron at 99.99% efficiency
  • The large square filter has greater surface area than other filters
  • Perfect for aeration or oxygenation systems to Filter out any contaminants.

Note from HBF: These type of filters are sometimes used as part of oxygenation or aeration setups.  I’ve also used a similar filter to help start a siphon.  See MoreBeer’s Sterile Siphon Starter for more info on that process.  The basic idea is you use a compatible carboy hood and racking cane and blow into a compatible filter to start the flow of liquid.  The filter used in MoreBeer’s setup looks similar to this one, although I’m not certain it’s identical.

Oxygen Flow Meter [Assist with Wort Oxygenation]

CNBTR LZQ-3 Acylic Flowmeter Gas Acrylic Metal Fitting Oxygen Flow Meter 0-5 LPM

CNBTR LZQ-3 Acylic Flowmeter Gas Acrylic Metal Fitting Oxygen Flow Meter 0-5 LPM


From the product description, check product page for current description, price and availability:

  • Center distance: 65.5mm
  • Flow range: 0-5LPM
  • Working pressure: ≤0.6Mpa
  • Widely used for measuring and controlling the flow of oxygen
  • Product function: to measure gas single-phase non-pulsating flow

Most regulators that homebrewers use for oxygenating wort are simple setups – Example – via William’s Brewing.  They attach to disposable oxygen tanks (typically sourced from a local hardware store) and are little more than on and off valves.  No gauges, no pressure control (other than the degree to which you open and close the valve) and no flow control.

Time and rate give you an idea of how much oxygen you’re really adding to your wort.  Time is easy to track.  Rate, not so much, at least with typical homebrew O2 regulators.  If you want more or less oxygen for your next batch, it’s mostly a guessing game.

Enter a flow meter.  This particular model has a range of 0 to 5 LPM.  This model also appears to have an knob that allows you to adjust the flow rate.  Note: .6 MPa is about 87 PSI.

With both time and flow rate you can establish a more reliable baseline to work off of.  This information should also help you to get better repeatability between brews.

Note that these are typically used for medical applications.  I’m not sure what the barb size is.  You will need to figure out tubing and connections to a compatible regulator and aeration/oxygenation stone.
