Actual Wyeast 1056 as first fermentation, do a yeast starter with the high gravity yeast and add after 1-2 days when fermentation from 1056 is at its best. Add 2.5 dl ground cold brewed coffee (vietnamese) and x3 vanilla to primary after fermentation is done (~ 4 weeks) let it set for 1 week. Add lactos (~250g) in keg.
