I make beer as well as wine. Both are made in my basement brewery/wine
cellar with a lot of the same equipment. Regardless of the beverage all
equipment is washed immediately after it's use. This goes for bottles and
kegs also. For wine I let the equipment and bottles drip dry and take no
further action. For beer I clean as above but before I use carboys, pumps,
tubing or bottles I treat with Iodophor. I add some citric acid to the
Iodophor solution to lower the pH. I understand Iodophor is more effective
in an acid pH. I keep some pre boiled water handy to run through my pumps
and tubing after Iodophor treatment because some solution pools in those
items. Carboys are drained and inverted, then covered with aluminum foil
until they are filled. Bottles are emptied, allowed to drip and are
immediately filled with primed beer. I don't let the Iodophor dry in
containers. In the past I noticed a film that formed on the inside of beer
bottles when they were treated with Iodophor and allowed to dry before
filling.

Since I make beer and wine in the same place, and since beer and wine yeasts
are floating around in the air, I have to be especially careful with beer
wort. I've had some batches of beer ferment much lower in final gravity
than I expected and think they may have been contaminated with wine yeast.
So, for me I'm pretty lax when sanitizing for wine but over cautious when
sanitizing for beer.
