looks like efficiencies were at 65% for this high gravity beer ( my first and only my second all grain beer to date
I was aiming for 6 points higher. In hindsight if I had boiled for a little longer and lost 600ml I would have arrived at my target.
I started out on the kitchen hob but moved outside to the gas ring which was better able to keep a rolling boil. Maybe next time it would be closer using the gas ring for the whole boil?
I gave sparging a go at 75 degC too. I originally intended to use 5 litres but ended up using 2 litres in the kettle to maintain mash temp(90 min mash)
Despite wrapping in two duvets it did drop about 5 degrees. A quick top up with 1 litre at 30 mins and an hour helped. I found rocking the plastic bucket helped to stabilise temps too.
Anyone have any suggestions on how I could improve this brew in future?
Still learning and very grateful for the experience of the members on this forum
As it's your second attempt I don't think you've done a bad job at all!
All set ups are different and produce different efficiency...you can change things to try and improve but consistency is the first thing you should aim for.
