Hello all you hop heads, I am a relative newbie and have a few queries I hope you all can answer for me. I got the bug from Mr. Beer last Christmas and moved to NB 5 gallon batches in May, so I’m not brand new but still pretty damn green. Living in Virginia during the summer without a basement hasn’t been the best environment (in terms of temps), but hey.
PBW. How much do you all use to clean a 6.5 gallon carboy, and how much do you use to clean a 5 gallon brew kettle? I’m a bit confused because the posts I have seen do not differentiate between amount by Volume or by Weight. I am about to order a gang of PBW so I’d like to know before I execute the transaction.
Temperature. It’s been a hot summer. I have a second bathroom that I use only for my carboy, and I have a digital thermometer to gauge the ambient temperature in there. I also have the thermometer from NB pasted on the side of my primary carboy. Does said thermometer account for the extra degrees generated by the activity of the yeast? I have an improvised swamp cooler and get the ambient temperature down to about 68 degrees or less for primary fermentation, but I want to avoid the esters as much as possible. Can I trust the thermometer sticker to give me true data on the temperature of the wort during primary fermentation?
Wort Chiller. I now have a copper wort chiller from NB and used it for the first time recently. I am wondering, how cooled down do I need the wort before pouring it into the carboy? The “instructions” that come with the extract recipes are vague at best, something about not warm to the touch. Given that I put 2 gallons of very cold water into the carboy before the wort goes in, do I need the wort temp to be below 80? Or just below 100? And, as a tag-on query, what is a good thermometer–I have an instant read digital but it has a 1.5 inch draft at best and gets finicky when wet for a long period of time. I also have the old mercury type that came with the NB starter kit but it seems sub-par.
Aeration. I am currently doing the rock and roll method for this but apparently that can only get you to 8 or so PPM, as opposed to the 15 PPM from an aeration stone, is that right? If so I will order one.
Many thanks in advance you hop heads
