Do canned beers taste different from bottled beers?

It's very individual. If you use more, it speeds up the fermentation process but also alters the taste. I would recommend somewhere between 15-30 balls. But you should check what the directions say (yeast balls should come with some instructions on the back). Because if it's a different make to the one I'm used to, it might be completely different quantities.

A good wort should take like a warm, flat beer. It doesn't sound like anything is wrong with your beer but you won't know for sure until you taste it. If it tastes bad it might be a sign of infection.

I wouldn't brew beer with distilled water. It doesn't contain all the minerals you need for a good taste in beer. You could always use bottled water.

Yes! If you want your beer to taste good and not have 'beer swill' which tastes horrible - you should clean and sanitize your equipment really carefully after each brewing session.

Pairing beer and chocolate can be a very fun and tasty treat. Depending on the type of chocolate, there are several beers that could compliment the taste. Below is a site I found that goes through various chocolates and their best beer pairings.

Beer does not spoil in the same ways as other drinks. When a beer spoils, the taste characteristics change, not so much the texture. Most beers retain their quality for about 6 months. If stored properly, it should still taste good for an additional 4-6 months.

In order to be considered a trappist beer they must fulfill two requirements - the beer must be brewed onsite at a trappist abbey and they must be brewed for non-profit purposes. There are currently 6 remaining brewing abbeys in the world - five in Belgium and one in the Netherlands. The most recognized trappist beer is Chimay.

There is a check valve inside the coupler of the danby kegs that cause this problem. The valve is mainly there to prevent beer from back-flowing when changing the keg. Next time you change your keg check for a little black plastic retainer and also a small white plastic ball inside the coupler. Remove those (or just smell it) and you should notice that this is the taste/smell your beer has. I removed mine after this discovery, and there isn't any issues with the taste/smell since. I've heard this is a common issue with the Danby D coupler systems. Also, you won't have any issues with beer backflow when you change the keg, provided the line going to the tap is empty (which usually is if keg is kicked).

Draught (or Draft) beer is almost always un-pasteurized and therefore is more fragile. It should be consumed after being "tapped", and is generally truer to the flavors of the ingredients as pasteurization exposes the beer to heat and changes the flavor profile. Always use brewery approved beer line if you want to have foam free fresh tasting beer. Serving it through a plastic tube from the hardware or discount store or the plain vinyl tubing in your beer tap system you will wind up with a foamy, off tasting beer. Real draught beer is not pasteurized. It must be kept refrigerated between 35F. and 44F. A beer will become wild, turn sour and cloudy in a day or two. Below 44F. a keg of draught beer should last 20-30 days before it loses it's fresh brewery taste and aroma. Craft beers (micro brews) tend to have a shorter shelf life and you should contact the brewery for their recommendations. Why does my beer foam up? The 3 most often causes of beer foaming up are: The temperature of the beer keg The balance of the draught beer system pressures The cleanliness of the draught beer system I would suggest that you clean or replace the beer transport tube...
