I have just done 2 brews with SM40 as only malt. Did 90min mash on both. 1st brew the colour looks the same as their pic. As someone mentioned earlier it does have a sweetness to it that I wasn’t expecting. 2nd brew will be ready to drink in about a week. I was impressed with the smell and taste...
I have done the same as rude, using the 19l. I have done 6kg but it was a very tight fit. I use a little brown pump for recirculating, it plugs straight into my laptop charger.
I wish that I stumbled across this thread a few weeks ago. Made the 1st batch of sausages: lamb, feta, rosemary. Was a great learning experience and cannot wait to do it again!
