Notes

The Elusive Orval Clone....like the Holy Grail...to get it right. Opus Orval #1 was pretty close except I didn't do one thing to the secondary...so I had a beautiful perfect beer that was missing that special something....hmmmmm....what is it?? The Brettonomyces is the answer so in this one, I will do that by adding Brett via Omega Yeast "All the Bretts" and let the secondary go for 2 weeks after a 1 week primary. Then I will bottle in my 500 ml sturdy belgian bottles and age for at least 3 months before I start in.....(I hope I can exhibit some modicum of control over myself).
