Well I brewed this on the weekend it was based on this old-styled oaked WCIPA.

I just sprinkled a half pack on top of the 32oC wort around 11pm on Saturday and when I checked in the morning it was chugging along.
I actually forgot to add the oak chips on brew day so threw them in the next day and since I had the fermenter opened I took a sample.
It had gone down from 1.073 to 1.052 in under 12 hours so looks like it will be finished in 3 or 4 days.
I'll check it again tomorrow.
I also brewed an American barley wine with an OG of 1.112 but used Voss instead of Hornindal.
I will check that tomorrow too.
