First of all. Im new. My first batch turned out great. Now I might be getting ambitious trying to brew a lager. I boiled a quart of water with 6 oz. of liquid malt for about 10 minutes. I then cooled it to 70 degrees like the yeast pack said and then added the yeast to the starter wort. It is now 48 hours later and Ive got some very light bubbling but no real activity. There is also a pile of yeast at the bottom of the starter about a 1/2 inch thick. I thought starters were supposed to get going fast. My first attempt at a lager failed miserably and Im starting to get frustrated. Is this starter ever going to start?
