I am very new to the whole brewing experience and have my first beer fermenting in the primary. The kit said to let the beer ferment for 5-7 days in the primary or until the airlock bubbles once per every 10 minutes. I am at that point and do not have a secondary fermenter to rack it to. I was wondering what is the best way to check the SG of the brew without contaminating it at all? Or in the least amount possible. I am hoping to rack it within the week and bottle so I can start my next brew. The kit I used is an Irish Red Ale Kit from a local brewery shop with a OG of 1.056 and I obtained a reading of 1.055 when I brewed it. I know this is probably answered on other threads but I couldn't find them. I also know that I could potentially leave the brew go for another week or so, but I am getting impatient (its my first brew ). Any suggestions would be much appreciated.
