I almost exclusively use White Labs Yeast, I have used some Red Star dry yeast such as Montrachet, and Champagne for Apfelwein.
White Labs Ale Yeasts used to date:
WLP001 California Ale Yeast
This yeast is famous for its clean flavors, balance and ability to be used in almost any style ale. It accentuates the hop flavors and is extremely versatile.
Attenuation: 73-80%
Flocculation: Medium
Optimum Fermentation Temperature: 68-73°F (20-23°C)
Alcohol Tolerance: High
WLP002 English Ale Yeast
A classic ESB strain from one of England's largest independent breweries. This yeast is best suited for English style ales including milds, bitters, porters, and English style stouts. This yeast will leave a beer very clear, and will leave some residual sweetness.
Attenuation: 63-70%
Flocculation: Very High
Optimum Fermentation Temperature: 65-68°F (18-20°C)
Alcohol Tolerance: Medium
WLP004 Irish Ale Yeast
This is the yeast from one of the oldest stout producing breweries in the world. It produces a slight hint of diacetyl, balanced by a light fruitiness and slight dry crispness. Great for Irish ales, stouts, porters, browns, reds and a very interesting pale ale.
Attenuation: 69-74%
Flocculation: Medium to High
Optimum Fermentation Temperature: 65-68°F (18-20°C)
Alcohol Tolerance: Medium-High
WLP007 Dry English Ale Yeast
Clean, highly flocculent, and highly attenuative yeast. This yeast is similar to WLP002 in flavor profile, but is 10% more attenuative. This eliminates the residual sweetness, and makes the yeast well suited for high gravity ales. It is also reaches terminal gravity quickly. 80% attenuation will be reached even with 10% ABV beers.
Attenuation: 70-80%
Flocculation: Medium to High
Optimum Fermentation Temperature: 65-70°F (18-21°C)
Alcohol Tolerance: Medium-High
WLP013 London Ale Yeast
Dry, malty ale yeast. Provides a complex, oakey ester character to your beer. Hop bitterness comes through well. This yeast is well suited for classic British pale ales, bitters, and stouts. Does not flocculate as much as WLP002 and WLP005.
Attenuation: 67-75%
Flocculation: Medium
Optimum Fermentation Temperature: 66-71°F (19-22°C)
Alcohol Tolerance: Medium
WLP400 Belgian Wit Ale Yeast
Slightly phenolic and tart, this is the original yeast used to produce Wit in Belgium.
Attenuation: 74-78%
Flocculation: Low to Medium
Optimum Fermentation Temperature: 67-74°F (19-23°C)
Alcohol Tolerance: Medium
* WLP540 Abbey IV Ale Yeast
An authentic Trappist style yeast. Use for Belgian style ales, dubbels, trippels, and specialty beers. Fruit character is medium, in between WLP500 (high) and WLP530 (low).
Attenuation: 74-82%
Flocculation: Medium
Optimum Fermentation Temperature: 66-72°F (19-22°C)
Alcohol Tolerance: High
WLP550 Belgian Ale Yeast
Saisons, Belgian Ales, Belgian Reds, Belgian Browns, and White beers are just a few of the classic Belgian beer styles that can be created with this yeast strain. Phenolic and spicy flavors dominate the profile, with less fruitiness then WLP500.
Attenuation: 78-85%
Flocculation: Medium
Optimum Fermentation Temperature: 68-78°F (20-26°C)
Alcohol Tolerance: Medium-High
