Just read this article and it speaks volumes to why at BLAH and Tiger!Tiger! we have short lines (direct draw) & clean them in between every beer change, we use only stainless steel draught parts, taste every keg before serving, return bad kegs before they reach your glass, rinse glassware with filtered water, serve honest pours, and encourage our staff to constantly educate themselves on beer styles and flavors. It's also why we gladly serve tasters. All these things allow us to serve beer the way the brewer intended. Cheers.
