Parti-Gyle #2

2009 has been a wonderful year of trying out various low alcohol session beers, or what I like to call "table" beer. The Wayward IIPA provided the opportunity to run a true parti-gyle technique. The Small Beer from that was so clean, mild and perfectly brewed. It was so good, I brewed a huge 13 gallon batch, most of which got drunk in record time at a good friend's wedding.

Thirteen more gallons of small beer were planned until a special request was made. My nextdoor neighbor, after tasting the Scottish Imperial Stout, wanted to brew some for himself. A perfect compromise, and another chance to brew a true parti-gyle again.

After the wort for an Imperial Stout is drawn, another batch of low gravity wort will be drawn for a small beer. This time, the color will be much darker, but I imagine the taste will be as smooth as can be.

Much like the first parti-gyle, a couple specialty malts are added as the second sparge ensues. Some crystal & chocolate malt will build up a little more color and add a touch more malt flavor.
