I suspect the reason your last beer only attenuated to 1021 was due to a problem with fermentation. When you do the math, you reached ~65% attenuation, which, while distressingly low, is still something one experiences, especially with the little packets of yeast one gets with kits.
Kindly detail your fermentation for us from your last batch: type of yeast, how much yeast pitched, average temperature during fermentation, type of fermenter.
Managing fermentation is arguably the single most important skill brewers must master. You might wish to select another yeast (I remember you wrote elsewhere that yeast selection in NZ is poor) or do something else to provide more managability of your fermentations.
P.S. Ponga rā! Kapa o Pango, aue hī!
Thanks for that post. Yes yeast selection very poor in NZ. We have most of the safale/saflager types however. OK maybe won't add sugar... hopefully still strong enough alc with good fermentation.
With the other batch, here is a brief summary...
Plastic Coopers fermentater. In semi dark room out of sun etc. Safale Yeast 04.
OG 1062, FG 1022.
After 5 days it was 1030.
After 12 days it was 1024.
Pitched @ 16*C. Fermented @ 16-18*C for 3 weeks, then 18-19*C another 10 days. Re-hydrated the yeast in water before pitching. Steady fermentation for a week. Slow after that. Shook the bucket twice in the last week but only dropped 1 point.
Have since bottled, adding priming sugar so its only 1.9 carbonation. Hope its ok.

Oh I got Safale 05 instead of 04 for my next batch. Is there much difference? It said it ferments out better on the packet.
