Ok so my first attempt at a partial mash was going awesome.. I started with 150g of Choc malt cracked and fuggles hops, boiled for 6mins then steeped for 14mins. Added an amber ale extract and extra liquid malt to the fermenter. Topped with the strained and sparged mash. Then topped with cold water up until the 23ltr mark.. Missed something!! The dextrose!! ****!! So I added it before pitching my yeast.. Made sure it was well stirred in then pitched at the 23 deg mark. It's bubbling away atm but I am weary.. Has anyone made this mistake? Is it a mistake??.. If the dextrose wasn't fully dissolved, Will the yeast still ferment the undissolved sugars? Any help will be great.
