Anyone know the attenuation of this yeast?

I've gone to bottle my first AG today and the FG is sitting at 1.016-1.018ish. I was hoping for closer to 1.010. According to Brewers Friend it's giving an attenuation of 64.8%. If it's 60-70% it'll be fine I just need to earn to use a better yeast. If not I think u know what might have gone wrong but will condition completely in the shed to avoid bottle bombs in the house!

I know I had a slight issue with my mashing temp so might have some non-ferment able sugars. If still gives me a 3.9% beer so I won't complain too much. It's also very bitter (I messed up my hop and chill timings) so the sweetness probably helps there.

Could you give it another few days or is today your only bottling day option?

Was it just the one 5g pack in a 20litres batch?

Today's my only day. Back to work tomorrow and busy the next 2 weekends. It's been in the FV for 17 days already.

Yeah just one pack, although my batch came in at about 16.5L (I was aiming for 15)

You could try re-pitching from the trub in the FV. I just take one of my sanatised bottles and fill it a third full with trub and put a lid on it and put it aside. When you've got your new wort ready top the bottle up with your new wort, give it a gentle shake and tip the lot into your FV. Apart from that, the next time you're near a Wilkinsons you can get their Gervin S33 yeast for £1.75 for 11g, it's worth keeping a couple of packs in the fridge, just in case.

To make thinks simple for yourself just carb the bottles lower. As worst you just get beer fountains when you open a bottle and If you chill the beer for 24hrs min before you wont even get that

If its not dry hopped I would be tempted to leave it a couple of weeks ... give it a good shake and just wait... patience is the home brewers most powerful weapon.

Really you need to take sg reading a day ot 2 apart , if they are the same then fermenting may be over. Or stuck. . What was the starting sg?

It was 1.046. I know some cheap ale yeasts have an attenuation of 60-70% and this came out at 64.9% according to Brewers Friend. I also messed up my mash temp for the first 15mins and it ended up way too hot so there's be some unfermentabke sugars in there, so it's likely it has finished.

This is what I've done. Used about a third of a teaspoon per bottle instead of my usual 3/4s.

Hope it behaves for you.

I was happy that my first AG brew was drinkable (it only got.down to 1.028 after mashing at 70c....) it has become a very drinkable and enjoyable (by now me and 3 testers) pint. So much so I'm considering do a larger batch, despite the high speciality malt bill, and planning to mash at the correct temperature.
