Back experimenting... Brewed up 11l of a kits and bits DIPL tonight. Hopefully it is strong, well-attenuated and bitter with a big hit of delicious Centennial. A bit over 1.070 OG and 100+ IBU pre-fermentation.
1.7kg Coopers Mexican Cerveza kit
150g Light Crystal Malt steeped
25g Centennial @15mins
50g Centennial @5mins
75g Centennial @flameout
75g Centennial dry hop to come
Fermented with Coopers kit Ale/lager yeast blend (slurry). It is currently getting very cold in my Cool Brewing Bag with a big ice block in the wort and another few ice bricks around the fermenter. See what temp it is in the morning, then I'll let it come up to where I want it to ferment at.
Somehow I'm sure it's also common in commercial breweries... I have a feeling PB2 knows something that might not be common knowledge.
I've been using the kit ale / lager yeast blend for the past 4 batches (and just pitched it into a 5th about an hour ago). There might be a bit of Wyeast Gambrinus lager yeast in there too, but it didn't seem to be doing anything after 72 hours, hence the original kit yeast pitch. I've been using it at lager temps, 11 or 12C, so the ale portion isn't doing much. It has attenuated quickly and fermented cleanly, then dropped nice and clear.
So I can vouch for the lager portion... Wouldn't mind giving it a run a few degrees higher so that the ale portion can contribute, but it's just not going to get that warm here in Canberra anytime soon.
I've been successfully using PET bottles for about 6 brews now.
There doesn't seem to be anything wrong with the screw on bottle tops but I do see them on sale.
So I'm wondering when does one replace the tops?
Are there signs to look out for or will it be fairly obvious when they are no longer serviceable?
Hopefully a short one. So I've given my fermenter a clean with water and a clean cloth. Then I've filled it up with warm water and added sodium percarbonate. Soaked for 24 hours.
Drained the water through the tap then rinsed with clean water. Disassembled the tap.
The silicone part of the tap retains a very beery odour. Not bad, just strong.
It smell doesn't bother me but am I at risk of harbouring some bacteria in the tap or something if I don't do something additional to clean the tap? In the past of soaked the disassembled tap in its own special bath of perc but the odour doesn't go away.
Anything I should be doing.
