This wand kits are an easy way to use the stone (a porous stainless steel outlet for microbubbles of oxygen to be infused in your wort). The wand kit includes the 60cm stainless steel 8mm OD wand and the aeration stone screws into the end using an MFL thread so it can easily be removed for autoclave or dip in an acid solution. The kit also includes a stainless clamp and 2 meters of vinyl tubing.
-650mm total wand length (which makes it ideal for large batches)
Attach it to an aquarium pump or oxygen tank for the best results. You can also attach a HEPA filter to prevent contamination and choking. Professional brewery connects the wand to medical-grade oxygen tanks to achieve 7-10ppm of dissolved oxygen. You can sanitize or autoclave the stone after use.
Lager yeast (unlike the typical brewer’s yeast) is bottom-fermenting. So lower is the dissolved oxygen level, the less healthy will be the yeast colony and chances of a stuck fermentation.
If you are a kombucha brewer who wants to reduce residual alcohol %, then this is ideal for you.
