Has anyone struck problems with Cascade kits? The yeast seems as slow as a wet hen & works when it wants to {was tempted to stick a laxette in just to make it work} The first kit I used was choc. mahogony porter which took 21 days the next a lager. Had no intention of using their kits again but tried the porter last week & it tasted pretty good. It's been down @5 1/2 months. On the strength of that last Thurs I put down a lager. It's doing nothing. Temp steady @ 23 degrees O.G. 136.-----------------???????
