Hi folks. Made my first ever Pilsner Urquell clone yesterday (1st lager actually) and my 21L batch is a litre or two short but is 1048OG as opposed to my target 1044 OG. The fermentation is going excellently ( was left overnight at 20C, yeast is Wyeast 2278). I was thinking of added RO water to bump up the volume by a litre or so but am not sure if this is wise... advise? Also what temperature would you advise continuing fermentation ( I was thinking of 12C and finishing at end of fermenting at 20C to reduce sulphurous aromas)? Thanks in anticipation.
