Hi all,
I brewed a 53L lager (all grains) on Tuesday 27th May. It was a simple Pilsner recipe with moderate OG of 1046. I use a refractometer to measure the gravity, and this checks fine on water.
I used 2 x bohemian wyeast smack packs (the dates on the yeast were approximately 6 weeks old) and I made starters with both of them (using a stir plate) - 1 litre each.
The fermentation seemed ok to start with and it ramped down to 1022 by Friday 30 May. However since this date, its remained the same.
The FV SP was set at 12.2C with and looking at my trend data this didn't budge by any more than 0.1C.
I tried to shake the FV to get the yeast moving again but no joy on Thursday 5 June.
In a desperate measure on Saturday 7 June I rehydrated some Saflager S-23 yeast to see if the issues were with the yeast. Again this made no impact to the fermentation so on Sunday 8 June I ended up aerating the wort/beer mix again for 5 minutes using a pump and stone.
Anyway, Ive checked yesterday and today and theres no movement at all.
I have no idea what to try/do now. i realise that its probably only good for the drain now but would love to know what went wrong so that I can correct before the next brew.
I have made a few great ales but I realise these give less issues than lagers.
Can anyone advise.
I made a Coopers European in Feb this year and this also stopped fermentation at the dreaded 1020. I just put this down to a kit and probably poor yeast but i would have thought that this AG beer would've fermented in no time.
Can anyone please advise. Would love any ideas.
Regards
Tim
