I am planning on brewing a Lambic tomorrow. I am going to ferment in a 5 gallon glass carboy using Wyeast 3278. This is my first time using this yeast. I’m wondering how aggressive the early fermentation will be. How much headspace should I leave? Do I need a blowoff tube? I am planning on pitching and leaving in my basement at around 60-65 F for 12 months or so.
7lb Pilsner malt
3lb raw wheat
turbid mash
