It is especially refreshing drinking it real cold on a hot day. Also first thing in the morning after a hard night of drinking Whiskey when your mouth is so dry your lips are practically cemented shut.
Arrowhead has a bad after-taste as do many other brands. I go to the Ralph's with my 5 gallon refillable bottle and refill it with Glacier. Great water, crisp, clean-tasting, with no aftertaste. Refilling a 5 gallon bottle is only $1.75.
As far as bottled water goes I like Aquafina. I went to the store trying to get one but they were out so I thought I would splurge and get a Fiji Water. That Fiji Water did taste like Arrowhead aftertaste and all. I'll drink out of a toilet before ever buying Fiji Water again.
