Belgian Double - trouble

Okay I brewed a Belgian double and it looks and smells great. Tastes pretty good after a week or so in the bottle but it goes down warm, kind of like brandy. The OG was 1.072 and the FG was 1.008. I was shooting for something like a Grimbergen Double but this is off. Here is the recipe:

12# Pale Ale
12 oz Caramunich
8 oz Victory
4 oz Aromatic
4 oz Special B
2 oz Chocolate
1# Dark Belgian sugar

1 oz Fuggles @ 60 min
.5 oz Saaz @ 10 min

WLP 550 Fermented at 74F for almost 3 weeks.

Any ideas how to get closer to a Grimbergen or why the alcohol is so noticeably warm?

Thanks

It will be much better in a month or 3. Bigger beers take more time to come together. Don't rush this one, and your patience will be rewarded.

Time. That's all it's going to need. One week isn't long enough to judge any beer, let alone one up in the 1.07+ range. A lot of bigger beers will need at least a month or two of conditioning before hitting their prime. In some cases you might even be shooting for closer to 6 months.

Put these bottles in a dark corner and don't check any more for at least another month. In the meantime, you should get another brew going
