Bugeaud
I added 1kg at first and then another 0.7kg (1.7kg total)
this comes to 3.74lbs (@2.2lbs/kg).
I think you may have missed the extra 0.7kg as it was in the text rather than the original list of ingredients
It actually tastes like there is too much alcohol

No idea if it is just because its young or fusels or something else.
Thanks for your comment though
