W1, I may not have been very descriptive but that's what I did. I put the alpha in and mixed it about for 10 mins at about 68 deg, alpha is best in the 65-70 deg temp range. The mash was like play dough nearly impossible to mix, within 20 seconds of putting the alpha in it was back to liquid. I put the barley in about 66 deg, the pot holds the heat too well and takes ages to cool. I didn't measure the SG until the next morning, was aiming for 1.06 but as I put an extra 5l of chilled water in to get temp down to pitch the alpha, the SG was 1.059. I can't complain, am happy I didn't need to put any extra sugar in.
If this works out well for me and I decide to do a regular batches I'll build a press to strain the liquid out of the grain. I plan on using a grain bag for this run but think a mechanical process would be far better.
