I have been brewing for 10 years. During that time I have been an extract brewer, a partial mash brewer and finally an AG brewer. I went from a 3 gallon pot and the kitchen stove to a 3 teir gravity system using 3 converted kegs. I decided to build a HERMS system and upgrade to 20 gallons (yes, it is obsessive) and have spent the last 8 months designing and accumulating the parts; pump, heat exchanger, 28 gallon pots. I even purchased a 3' x 10' copper sheet to jacket my mash tun. Assembled and tested with 20 gallons of water it worked perfectly (although I think I am going to re design my heat exchanger). The Rub: Planning to brew my first batch last saturday I milled my grains on thursday. Friday I went to work and promptly got laid off. Now that brewery is packed up and in storage while I get my house ready to go on the market. sooooooo close to my dream system and sooooo far away from using it.
