Christmas in August. Santa Scott (one of four other Scotts I brew with) brought a homemade wort chiller down my chimney. Other than its assigned quarters – the shed – Coolio is on the fast track to BFF status. Copper tubing, three clamps, a hose adapter + tools = voila: no more ice needed to cool your wort. No more long wait for the big chill. Move up the start time for your billion buddies of yeast to get busy.
We inserted Coolio into the brew pot last weekend, after the boil. Hooked it up to the garden hose, now keep in mind it’s 90+ degrees outside. Hose gets the water into the tubing in the pot, then comes out the other side. Proving ground results: the wort cooled from 200 to 100 degrees in 8:33 – again, in 90+ degree heat. Imagine how quickly the wort temperature will plummet in fall and winter weather! Talk about catching a cold.
Looking online, immersion wort chillers run from mid $40s to almost $90, that’s before tax and shipping. You can buy materials for probably around $20-$30 while putting another notch in your DIY belt. Check YouTube, Google, etc. for instructions. Also, don’t forget to sanitize before sending it down to the depths of your pot to mingle with your latest concoction.
