I put a brew down yesterday. Mangrove Jack American Pale ale 1 kg LME 250 g Caramunich Crystal Malt Amarillo Hops Safale US-05 yeast I used the US-05 yeast as I have been reading the Its not good to use the yeast proved in the kits? I pitched the yeast at 22 deg 15 hours ago and there is still no bubbling in the air lock. Should I be worried? Can I add yeast provided? Or should I wait? Advice please??
