This bloke reckons that there's zero discernable difference in the final product when changing between 64C and 72C mashes
........
but I'm still not convinced that 70C would [on its own] cause 1020 FG.
Like "this bloke" my taste-buds can see zero discernible difference between all kinds of changes to my brews.

Ok there's a gazillion variables that will affect it and you could probably choose the right ingredients, water quality, and yeast strain and show the opposite to be true, but I'm still not convinced that 70C would [on its own] cause 1020 FG.
I've only done one AG so far, a pale ale from the have a go at AG "how to" on here. I didnt know a high mash temp caused unfermentable sugars and mashed at 70ð. I fermented it and it wouldnt go below a FG of 1020 so I chucked it. I would recommend you decide whether to keep it at the end of fermenting depending on your FG.
