This is an area that I have been experimenting with recently. I followed this recipe here:
60L batch
6.3kg Pilsner (Weyermann)
3.6kg Jasmine rice from Aldi
60min - Sorachi Ace 30grams
10min - Sorachi Ace 20grams
0min - Sorachi Ace 50grams
I had a large pot and used some of the pilsner malt and all of the rice and converted these separately overnight in the
BZ 100L with the pump re-circulating for the whole night as I just wanted to be sure it would convert.
When I boiled I had a huge amount of hot break. I pumped the whole lot into the fermenter and then fermented with Novalager yeast and then cleared this using the
Biofine A3. (NOTE: i forgot to add the whirlfloc tablet too.)
It was fun to use the rice but in retrospect I think I lost about 15L of beer due to the huge hot break sludge that was left behind. I generally do not get this when using flaked rice and maybe converting overnight released more fine rice material than it should have. I probably would not use rice again as the cost of the losses and my time were much greater than the savings not using the
flaked rice. With that said it was fun to use the raw jasmine rice as I have not done this for a long time so it was interesting to give it a go.
I totally would recommend the
Novalager for this batch as even small amounts of sulfur are noticeable in this beer style. I previously used to use the Diamond yeast for this beer style but the novalager is cleaner and saves time.
If you are feeling a bit lazy I have also done this
pilsner fresh wort kit which is made from 20% rice so you will get similar results however I think in comparison my recipe with the jasmine rice was slightly lighter in colour and slightly lighter in flavour but very much comparable.
