OK, cool. So like I said in another thread, I have taken the electric blanket out from under my fermenters and put it under my bottled brew to lift them up from 15 to 24 degrees. My fermenters should now run at about 15.. is this good and how long do I leave in the fermenters at 15? The "can" says 1 week but some say 2 weeks is better. What do I do?
WTF, 15c on the goldcoast? You lucky bastard. I'm struggling to get 16c average in mid winter in my sydney garage.
Back to the point. You'll be using an ale yeast in those Tooheys kits. Ale yeasts slow down under 18c, and are pretty slow at the 16c mark.
The extra week can't hurt it. That usually gives the yeast a chance to flocculate (laymans terms - "grab all the cloudy bits and drop them to the bottom, leaving a clear beer").
You mentioned earlier (or in another thread) you don't know how to use the Hydrometer. I'm not sure if there's anything up in the articles link at the top of this site, but I'll give it a go.
1. Make your beer.
2. Put your hydrometer into the test tube it came with
3. Pour some through the tap into it until the hydrometer floats.
4. Wait until the bubbles settle... give it a spin.
5. Take the reading. Going off your Standard knk recipe, it'll be around 1040. (1000 is the reading for normal water)
6. DRINK SAMPLE (honestly, are you gonna chuck beery goodness down the sink?! that's crazy talk)
7. Let beer ferment, take as many readings as you like over time. DRINK SAMPLES.
8. Your hydrometer will slow down round 1008 (give or take a few points).
9. When it's stable for a few days and hasn't changed, it's ready to bottle.
This is a lot more accurate than an airlock. Use it, but don't pay any attention to it.
On Supermarket kits - you've got an okay range to try. I prefer the Coopers over the Tooheys, but theyre all fun experimenting with.
For some more beginner tips, www.Countrybrewer.com.au (no affiliation) have some clone recipe sheets, tips and stuff, and a hydrometer alcohol chart for you to work out the rough percentage of your kits.
Hope this info helps.
