Parti Gyle!
The first 5.5 gallons is drained into the kettle for Big Pig and the mash is refilled and circulated before being drained into a second kettle for Little Pig. The second mash is capped with 1/2# of chocolate malt to add some color to Little Pig. Big pig is pretty big IPA with heavy late hop additions. Little pig is a darker and weaker English beer... dark mild/brown.
Using a 60%/40% ratio for the 2x5 gallon split.
