Sweet, heavy taste

[rhino18]

Hello,

I'm fairly new to beer making. I used extract a couple of times and those came out well. But the last few (different recipes: primarily two-row, but I've changed yeast a couple of times for the sake of experimenting/learning, fermentation temps and times have been about 70 degrees and 2 weeks) have acquired a heavy, sweeter taste. Some bottles I have had for about 6 weeks have not gained or lost any of the "weight."

They taste fine and look great, but as someone still learning, what are some possible causes for that sort of outcome? Thanks!

You mention "primarily two-row" so are you brewing all-grain or extract? Quite a few things could cause a sweet heavy taste. Mash temps help determine amounts of fermentables vs unfermentables, so maybe too high of mash temp, or you might be using too much specialty grain (eg. CaraPils) that don't produce many fermentables, or yeast that doesn't attenuate well, or yeast that produce flavors that give it a heavy sweet taste fermenting at 70F, or extract that just isn't going to reach a FG of less than around 1.020. If you could post your recipes/mash temps/yeast types that'd be good.
