I have been brewing for 6 years and have developed some great recipes that have been well received at competitions. My equipment used to be an all-grain setup using a standard 10 gal kettle and 10 gal cooler mash tun. Fermentation has always been in buckets in a temp controlled chamber.
However I recently "upgraded" to a 3-keggle setup using all stainless fittings and connections so as to brew larger volumes. Ever since that time, my beer has been lifeless. Even recipes that I have been brewing for a long time seem to lack that usual punch and drinkability. No pop and all fizz. :(
I believe my system is "dialed in" using Beersmith and I am hitting volumes and gravities as I should. I am just not getting the same flavors that I am used to.
