You must be psychic because I literally just brewed a tripel 2 days ago and pitched WY 3864. Similar recipe, too. I used Styrian Golding, and also added honey and 1 tsp fresh orange zest at flameout. I can't wait to taste the results! Smells fantastic already. Yeast took off in less than 6 hours at 65 F and is one of the most vigorous fermentations I have witnessed in all my days.
