Oxygenation of wort is essential to proper yeast growth and overall health. And healthy yeast has the largest impact over final beer flavor than about any other variable. Acheiving 8-10 ppm (parte per million) of dissolved oxygen (DO) in your wort prior to fermentation is vital to acheive your best tasting beer. Too little and yeast growth is stunted and off flavors can be created. Lag times increase and final gravity may not be reached. Too much and and you can end up with excessive fusel alcohols in your finished beer. While dissolved oxygen levels are vital, the equipment to measure DO isn't cheap. Inexpensive hand-held models are upwards of $300. And lab grade models are well over $1,000. However,we've done extensive testing to allow you to acheive proper DO levels with wand type and in-line type oxygenation systems so you can be confident you're acheiving your DO levels. Knowing the FLOW is important - other regulators simply regulate pressure and depending on your downstream restriction the actual flow can vary widely!

Oxygenation Stone Selection
Oxygenation stone selection is fairly simple but there are a couple considerations. First is the micron rating. The smaller the micron rating, the finer the bubbles that are created. The smaller and more numerous bubbles have more surface area and dossolve in the wort more readily. However, there are drawbacks for fine micron ratings (below about 2 micron). And that is the inability of sanitizers to readily penetrate into the stone to kill bacteria. Therefore they must be boiled to be properly sanitized. While the porosity of a 0.5 micron stone is smaller than most bacteria, they must be handled with gloves or the oil from your skin will plug the small pores. Through extensive testing, we've selected a coarser 10 micron stone for our oxygenation system that is a perfect balance of durability and performance. Simply put, it's smart engineering. Easily penetrated by sanitizers, durable enough to be handled with bare fingers, and performance approaching the more fragile ultra-fine stones. We feel that the small amount of additional oxygen is well worth the convenience of easy sanitizing and normal handling.
