Your top three styles

English BW
Imp Stout
Saisons

DIPAs and imperial stouts are easily one and two, respectively. After that its mood based.. Right now, in cold weather, it's Baltic porters. During the summer it was Hell or high watermelon. Mmm golf...

It changes pretty frequently, but right now I'll say, in no particular order, my favorites are ESB, porter, and dubbel.

IPA
Old Ale
Dark English Mild
with Quad following very close behind

I
P
A

IPA/DIPA
German pilsner
Saison

Easy number 1 for me is IPA. Stouts would come in second. The third might vary depending on season or mood but I would go with Porters most of the time.

IPA
Stout
Barleywine

Imperial Stout
Barleywine
Old Ale

1. On tap
2. in a can
3. in a bottle

but seriously style wise: Experimental, milk stouts, and just about anything that promises to taste good.

Sours/wild ales/gueuze/lambic
Gose
Flemish Oude Bruin
Berlinerweisse

#3: IPA
#2: DIPA
#1: TIPA
[When they figure out how to make a Quad IPA, I'll adjust this list accordingly...]

Farmhouse/Saison

Barleywine

Imperial Stout

I appreciate and enjoy all beer styles except for light lager, lager and pilsner.

Helles lager
IPA/DIPA
Stouts of all kind

Saisons are a close runner up.

Ipa's, stouts and porters..

Flanders Red
American Wild Ales
English Barleywine

You get another go. Stouts and Porters are the same style.
Mild, bitter, stout/porter

IPA
DIPA
Lambic

1. Lambic/sour
2. Imperial Stout
3. English Barleywine

If I had to pick 3 they would be porters (most varieties), stouts (same..most varieties), and belgian quad ales.... a close 4th would be farmhouse ales.

I would have to say:

1. American amber ale
2. IPA
3. ESB

English Pale Ale

American Pale Ale

India Pale Ale

1) Stouts/Porters (too similar to count as 2)
2) Saisons
3) Brown Ales

1 Barleywine
2 Stout
3 Old Ale

As far as those I would drink on a regular basis:

Lambic
Saison
Weizen

Maybe a different list if the choice is among styles with the biggest flavor.

Belgian Strong Dark Ale
Dopplebock
Baltic Porter

Tripel
Hefeweizen
Witbier

Old ales
Imperial Stouts
Tripels

1. Porters and Stouts, esp. Oatmeal and Cream Stouts
2. Scottish Ale/Wee Heavy
3. Anything in the Bock family

Honorable Mention for Bohemian Pilsners

Saison
American wild ale (read brett fermentations)

I really expected to see IRS up there. Wow. Learn something new every day I guess.

IPA
Stout
Belgian Quads

stouts
porters
RIS

All forms IPA/DIPA,BIPA, English,West Coast, you name it

RIS , especially barrel aged varietals

Anything with Rye in it

IPA - it's my go to style, if I'm buying a six pack of something it's more than likely this

Stout - another go to style, big stouts always make me smile, and barrel aged stuff is even better

Saisons - love the distinct flavor of a saison and have been lucky to have great ones by Fantome and Hill Farmstead

1. Belgian Strong Dark Ales
2. Imperial Stouts
3. Hefeweizens

(1, 2, and 3 subject to change without notice.)

This changes with the seasons for me, but I would have to say:

Stout
IPA
Pils

Lambic (gueuze specifically)
American sour/wild style
Flanders red

Though sometimes barley wine or stout edges in to the #3 spot... usually in the winter when I'm craving those styles

Imperial Stouts
