Notes

This is version 2
Original had 300gm of Munich, changed this to 300gm of Shepherds delight for more mid level flavour.

Mash temp at 65 for 20 mins then raised to 69 degrees worked well for mouthfeel.

Try a late addition of the dark malts this time so the Mash Ph doesn't drop to far. Get in seperate bags. This may also impact the flavour of the beer.
