I've decided to brew my very first Lager, after some good results on my Ales. I did a proper research on methods to try a refined process, specially when it comes to fermentation schedules and temperatures. I chose a simple Vienna Lager recipe as my first attempt, and it's now finishing the first week on primary (controlled temperature at 12ºC). Since I'm new with this yeasts, I wanted to take a sample to ensure everything it's working fine. It should be, since there's still yeast activity visible on my fermenter. Some egg-like smell was perceptible during the first five days, as it was described on various forums. But I want to make sure I'm not compromising a fermenter for 3 weeks with useless wort.
Is it safe after one week on primary?
Should I sanitize the faucet before taking the sample?
