hope you're doing will, is it possible to have 20% alcohol beer!!!. I just batched my first homemade beer. I used a 7Ib barely syrup with 1Ib malt barley in 20L wort and final volume was 17L. by using a refractometer, the reading was 14 brix. After a 5 days using safale us-05 , the bubbles in the airlock slow down so I took another readying which was 8 brix according to calculations I should have a 5% alcholo beer however I used another refractometer for measuring alcohol V/V and the readying was 20% alcohol, is this possible or I have done something wrong .is it still good to consume it?.
