Take the worth to a boil, then cool between 20 and 45 Celcius. Transfer worth into a topped kettle, add probiotic capsules.
To reduce risk of infection, cover with plastic wrap, do not aerate (lactobacillus plantarum works fine without oxygen). Keep temperature below 45 to allow growth, but not too low to risk infection. The fastest temperature appears to be around 30C.
Add 1 billion cells per liter for a 36-hour souring, or 0.5 billion cells per liter for a 72-hour souring. For this 20L recipe, that's 20 billion cells, or 4 capsules, for a 36-hour souring. Half for the 72-hour souring. Expect good results at 30 Celcius for 36 hours.
The proceed as usual: boil, hops, chill and transfer to fermenter with the yeast.
Ferment 10 days, then add raspberries. Bottle or keg 7 days later.
The desired probiotic contains Lactobacillus plantarum. The suggestion below contains 5 billion cells per capsule.
