Greetings Brewers, I brewed a partial mash IPA this weekend and I have a question on batch sparging. I use a picnic cooler Mash Tun and do a strike and a single sparge. For this brew I took samples of the first and second runnings to measure the gravity of each - just to see myself how much I am getting in that single sparge. Here's the recipe: 5 kg Weyermann Pale Ale 0.5 kg Stamag Melanoidin 0.2 kg Crisp Malting Maris Otter 0.25 Light DME 20 g Magnum for 60 min 20 g Mandarina Bavaria for 30 min 10 g Saaz for 3 min 30 g Lemondrop for 7 days I struck with 18.6L at 67C for 45 minutes, then sparged with 12.5 L at 67C for 10 min. For the first runnings I recovered ~12.5 L and the gravity measured 1.066 (temp. corrected = 1.068). For the second runnings I recovered ~10 L and the gravity measured 1.026 (temp corrected = 1.028). I think I have convinced myself that a second sparge would not yield much. Anybody have a different view? Thanks and Cheers!
