65L isn't available in Canada. I also haven't ventured into large grain bills yet, so the 65L really wouldn't be of any use to me. I also have no need to brew more than 5gal batches. I may be making it sound like I'm having issues with my unit, but I'm really not. I'm just trying to optimize it and get the most out of it as I can. I'm going to incorporate a few extra steps into my brew day to improve things.From all your posts, it sounds like you really need one of the 65L units. I'm normally doing 12lb or so grain bills, and the 35L unit handles it fine. I did do the Russian Imperial Stout recently, and that was 20lbs. Won't do that often.
