I really like Marks & Spencer's Adnams Mosaic single-hop pale ale, and its keg cousin Jack Brand Mosaic pale. I know that, using extract, it can be hard to get a brew properly pale. I'm guessing that by using pale extract, pale malt, lager malt and possibly crapils as well as a pilsner yeast, and Mosaic hops at the aroma, bittering and dry hop stages, I'll get somewhere near the mark. But does anyone have any ideas on quantities or possible tweaks?
