alright guys, on the back of the packet it says tempreture range is between 9oc to 22oc, ideally between 12oc to 15oc. has anyone used this yeast strain at 18oc to 22oc? it must work at those temps im just wondering how well and if my lager will still be crisp at that temp or if its better to wait till the cooler months to get brewing lager again. cheers guys
