To go on a slight tangent, in designing your recipe, did you take into account the efficiency drop you will see with a beer that big?
For example, if you’re using a tool like Beersmith for recipe design, and you’ve got it dialed in to work well with your setup to provide accurate OG predictions for 1.060ish beers, then you'll probably be quite surprised/disappointed with your OG on a barley wine if you don't adjust the software settings for the big beer.
Ways around this problem include:
- Design recipes that assume a lower efficiency (which means more grain will be needed to hit target OG)
- Sparge enough to get a pre-boil volume MUCH larger than you think you need, then boil for 2-3 hours to get your target volume into the fermentor
- Offset the efficiency loss with DME in the boil (not my preferred solution, personally)
