Currently raising this to the boil, I had a load of bits and pieces leftover from previous brews including 3kg extra light DME from my partial extract days. So ordered some williamette and centennial from CML on Thursday and paid the princely extra sum of 25p to upgrade to 1st class so they arrived Friday

Couple of issues, I mashed-in in 10litres of liquor and set it away recirculating but it was pretty clear after 5 minutes that the grain was blocked, so I recovered the top plate (ouch!) and gave it a good stir to loosen it up, I'm guessing the wheat content at 20% of the grist caused this, I didn't give it enough time to absorb enough liquor before I recirculated but it got going again fine.
Second issue and I'm kicking myself, I forgot to treat the mash liquor to reduce my alkalinity from 196 to around 0-20 which is a bit of a pisser because this is a pale and hoppy brew and the resulting mash ph was 6.1 doh. I'm taking a little solace from the fact that I remembered for the 21litre sparge, and 2kg of extract added to the boil is well over 60% of the sugars so I'm hoping it'll recover the situation a bit.
90 minute boil to add some colour, time for a coffee and a sandwich now :)
