Wow, for a 2nd brew, there are plenty of gadgets, gizmos and processes here, too many for me.
The most complicated bit of kit I have is a fridge, heater controlled with an Inkbird controller.
I have a few buckets, a pot that just fits on the cooker top, a couple of mesh bags for grain and hops, few lengths of tubing and a syphon plus kitchen sink for cooling the wort in the pot and that is it.
The FV goes in the fridge for 10 days at 19 degrees, whether there is any airlock activity or not. It has a further 4 days at around 4 degrees.
It is then transferred from the FV to a bottling bucket where a solution of Dex Sugar is added to carbonate... Amount depends on whether being bottled or bagged for the handpull.
That is it pretty much, no cooling or warming coils, no tubing around buckets, no Co2 flushing, no gadgets or gizmos, a plastic jug to rinse grain through though is necessary for me .... Nearly 50 brews (AG and Partial Mash) giving fantastic results.
Everyone has their own views, ways and most think their way is better than anyone elses. That's the way it is but it is each to their own and my way is least complicated, least fuss and least gadgets give me what I want.
