Homebrew Syrupy aftertaste

[Beerbom]

Hi All and Cheers,
I consider myself well and truely a novice brewer. I have been home brewing 3 years now, I run 2 fermenters and have 2 kegs on the go in my beer fridge, one drinking and one carbonating and chilling.

I brew the morgans wort tins generally with 1 kg brew enhancer plus around 300grams of dextrose plus premium ale yeast supplied by my brew shop plus seeped hops 12grams, included after yeast.
I like my lagers normally. I control temperature ferment in a fridge usually 2 to 3 weeks and then cold crash at 5° for another week, then keg.

I make a heavy beer usually around 4.8 to 5.0 % I like my brews, although at times I think they have a syrupie after taste.

My mates also comment that they taste strong.

My question is... has anyone else noticed a syrupy after taste in their brews... my thoughts are it could be from the wort tins.. ?
Any of your thoughts or comment will be appreciated.
Cheers.

I'm sure someone on here will be able to help you. I haven't brewed with a can for about 17 years, so can't really comment with any useful insights. Couple of questions, what's in the brew enhancer, and which yeast and how much do you use?

Could be a stalled fermentation, what are your starting and final gravities?

I stopped using liquid malt (which I presume your Morgans is) because of the off flavours which I would describe as the smell of hessian sacks translated into a flavour. I changed to quality dried malt and the flavour of my brews improved immensely using the partial mash technique. Your question about a syrup flavour sounds like incomplete (stalled) fermentation.
