A fun extract wit I did was this, but might be a little too summery. Then again, it might help you to forget that it's winter!
0.5 lb carapils
6 lb wheat LME
3 lb amber LME
.5 oz. Hallertauer (60 min)
.25 oz. Cascade (20 min)
.25 oz. Hallertauer (20 min)
.25 oz. Cascade (aroma)
WLP400 Belgian Wit Ale Yeast
1/4 tsp crushed coriander (5 min)
2 cans crushed pineapple in juice, no sugar added
Steep grain 30 mins @ 150-160. At 200 degrees, add amber LME. Begin boil. Boil bittering hops for 60 mins. Add remaining LME with 15 mins remaining. Add coriander with 5 mins remaining. Add pineapple just prior to flame out. Add aroma hops just prior to pitching.
Bottle after 3 weeks. Use 5 oz dextrose to prime.
The pineapple flavor is not as evident if you bottle right after fermentation, it grows over a couple weeks, which is why I suggest the 3 week lag. If you're willing to let the bottles sit a while, then you can bottle right after fermentation is complete.
Hope you like it!
