Indentifying a wild yeast infection
Posted: Thu Sep 02, 2010 4:50 pm
My Ordinary Bitter that I brewed in late July and bottled Mid-August has been infected by something, and I'm not sure its all bad. I drain poured the first couple bottles I opened, but decided to hang on before dumping the batch.
5.5kg 2 Row Canadian Pale malt
0.5kg Carafoam
19g Pride of Ringwood 60min
9g Pride of Ringwood 30min
19g Kent Golding 15min
9g Kent Golding 5min
Pitched rehydrated SA-04. Cooling this beer (18L post boil) took almost twice as long as anticipated (immersion chiller) and I think this is when it picked up the infecting agent. I racked it on Aug 1, bottled on Aug 15.
It finished far lower than intended (1.004 vs. 1.012) making it a 5.8% ABV brew. I'm getting some quite herbal (thyme, basil, sorrel) and musty notes while flavours are both sour lemon and pear like with a bit of a metallic finish.
This was my first time attempting a lighter beer, and first time using the PoR hops, and first time with an infection, so I'm not exactly sure what can be attributed to the infecting agent versus the Hops although I'm pretty sure the mustyness is from the infection.
Anyone who has experience with wild yeasts/infections I'd appreciate some feedback as to whether its worth keeping this beer or not.
