Been thinking about capturing the beasties at a mates farm. Rather than doing a full batch and leaving it out overnight I'd probably start small with a few bottles of DME scattered around the place. Though that hasn't stopped me looking at solutions for a coolship for my size batches (10 litre / 2.5 gallons). Something like the 12 litre version of this looks very cost effective https://www.nisbets.com.au/vogue-stainless-steel-half-size-gastronorm-tray-200mm/dn712 So getting back to the topic, it also occurred to me that I might be able to use it to scratch another stupid idea I've been considering - open fermentations of standard sacch batches. So before I get carried away I was wondering if anyone else has been trying open fermentations. What's been working, what hasn't, what type of vessels are you using? Or any other advice on when to use it or not use it?
