I recently made some changes/upgrades to my brewing equipment and, on my first batch with the new equipment, have noticed a HUGE increase in efficiency. I upgraded from a hydrometer to a refractometer, built a sparge out of PVC to continually sparge in lieu of batch sparging and purchased an oxygenation kit to introduce pure oxygen to my wort. My results and recipe are listed below. Any feedback on the cause, or false readings for that matter, would be appreciated. This is the second time I’ve brewed this beer and both results are listed below. Keep in mind my first batch was using a hydrometer with batch sparging and the second was a refractometer with continuous sparge and pure oxygen.
