Notes

BREW NOTES
First brewed 30/08/2015. Want to try push mash temp up and see whether improves mash efficiency.

MASH NOTES.
Only getting around 60-63% efficiency. Have tried all manner of things to bump up. Looked through old notes and remembered that even with a pre Tun heat up, I still need an extra 2 deg C on top of brewers friend calcs. Last 3 brews all around 64-65 deg C mash temp on purpose.(wanted drier beers then but efficiency suffered) This time have bumped up mash temp extra 2 deg aiming for 67-68 deg C over 90 mins. Extra 2 deg C last thing to test before changing to smaller esky cooler Tun.
Ambient temp 18 deg C (end of winter) 30/08/2015
I have tun insulated with cardboard and wrapped in blanket.
Single Infusion.
Grain temp 13 deg C
2.5 L/1kg grain
Strike (brewers Friend) 21L @ 77deg C.
Actual Strike 79.5 Deg C. Adjust for your equipment.
After 30 mins sitting on 67-68 Deg C. Stirred
After 60 mins sitting on 66 Deg C. Added 2L boiling water. No noticeable temp changed.
After 90 mins finished at

Nottingham yeast (Danstar) re-hydration 1.064 slightly high for 1 packet. I re-hydrated only.
Original Gravity 1.076 way higher but 22L
Final Gravity
ABV %

After BREW Notes
Mash temp rise to 68deg C haven't worked. Hit 1.076 but 22L. This is 63% which is my standard efficiency. I added 2L of fresh water to bring it down to 1.070 may add another 1L to make 1.067. Brewer's Friend calcs at 63% efficiency. Had my usual 34 liter to start boil. Left a bit more in pot so not as much trube went in, but still 6L off. Not sure why the extra boil off today.
The extra 2L of water isn't something I like to do, but ABV would be too high for 1 packet of dry yeast. Extra water will bring with some oxygen to aid yeast. Should it attenuate as per all my other brews 80%+ 1.010 i'll end up with an imperial-ish 7.8% 1.012 finish 7.6% down side is I wanted a hoppy plain-ish IPA lucky the extra IBU's are in it as it will still be a balanced beer with a 1.012+ finish.

FG 1.016 added extra water.ABV 6.69%
