First of all, this is an awesome site for someone just starting out in homebrewing. Didn't take me long to figure out that I needed to join here. Got a kit from Northern Brewer last month and currently have Block Party Amber Ale (extract w/ steeping grains) in the primary as of Feb. 13. Has been fermenting at about 65 deg. since then. Took a gravity reading today and it was 1.018. OG listed in the recipe is 1.042, didn't have hydrometer on brew day. Beer smelled good but had a green apple taste. Assuming that the beer is still "green", so I moved it to the garage freezer with my newly assembled stc 1000 temp controller. Set it to 67 deg and plan on leaving it for another week or so before i take another reading. Am I right in thinking that it still needs more time fermenting?
