I've used it a number of times, with different results. I've currently got 2 different batches of it. The first batch is pretty funky, the second more subdued (I did pop a little lacto in it after about 6 weeks). I put cherrys in the first batch and split the second batch and did mango and strawberrys in the second (separately).
The yeast will go sour but I had one batch that didn't last year.
The last batch of it I did I mashed at 72C and tried to get it to ferment between in 25-27C. Mashing at the higher temp produces longer chain sugars that normal ale yeast can't eat but funky bugs can.
A few points I've found with using this yeast:
- It can vary from brew to brew in both funkyness and how sour it will go
- It can be sour within 6 weeks but not always
- It can ferment pretty quickly, make sure you have a lot of head room in your fermenter and a blow off tube
- On it's own I got bored with it reasonably quickly but it goes well with fruit
