Congrats on ordering the brewing worksheet! Use it for just one brew and I promise it will become an indispensable piece of brewing gear.
I'm preparing your shipment, but in the meantime I recommend you pick up some wet erase markers to use with your worksheet. I've tested a few and my favorites are the Expo Vis-a-Vis fine point markers. You can buy them at Amazon from the link below. Your local office supply store may carry them as well.
Enjoy the worksheet!
