I've been a lurking while I brewed my first beer in several years. I decided my first beer would be a Wheat beer as it's my drink of choice these days. I haven't ended up with the beer that I was expecting, but it's drinkable and pretty strong (about 5.3%)...I guess I wanted something a bit lighter like the wheat beers you'd find on the supermarket shelf. If anyone has any tips, or pointers where I went wrong, please let me know. I am a noob to this, the last time I brewed it was from a Boots kit!
I brewed the Bavarian Weissbier as per the packet instructions, with Brupak Premium Grade Malt Extract, with a starting gravity of about 1052. After about 3 days the fermentation seemed to have stopped, I tried rousing the yeast from the bottom and added Yeast Vit but fermentation didn’t re-start and gravity never dropped bellow 1018. At 5 days I transferred to a secondary fermentor with airlock.

At day 7 the gravity was still 1018 so I thought 'sod it' and siphoned it into primed bottles.
Tonight...day 11, a little early to be supping I guess, I've poured myself a pint. As you can see it's quite dark for a wheat beer, nice and cloudy. The gravity now seems to be 1011. It’s pleasant and drinkable, but is too strong for my taste, though having finished it I’ve had to venture back under the stairs to find another bottle to throw in the freezer for 10 minutes

Would I have been better off using 1Kg Spray-Dried Malt Extract instead of the 1.5 Kg Brupak Premium Grade Malt Extract?

(The glass is no indication of what I was expecting

Would like to make a lighter, more refreshing wheat beer next if anyone has any tips - I've searched the forums but not found too much about wheat beer...
Cheers
