Nice solution to prevent star san to be sucked backwards during cold crash. Stop by at @arlans_bryggeri and click follow! 😎 . Reposting @arlans_bryggeri:⠀ …⠀ ”I made this thing to prevent suck back of oxygen when cold-crashing. Star san is pushed from one jar to the other by the co2 developed during fermentation, creating an oxygen free vessel. So, when cold-crashing, the only thing (hopefully) being sucked back will be co2. ⠀ I’ve seen a lot of fancy versions online. My version might not be fancy, but it works (and it is really cheap to make!). #coldcrash #diybeer #diy #craftbeer #homebrew #homebrewing #homebrewingonly” . #Homebrewing #craftbeer #beer #allgrain #allgrainbrewing #beerporn #beergeek #brewporn #diy #skellefteå #electricbrewery #beerstagram #brewstagram #brewhardware #beerlover #beersofinstagram #brewing #homebrew #craftbeerporn Use hashtag #hillbillybrewing for a chance of repost —
