I don't have mine on a thermometer either... Just figure the glasses are in the mid 60's and the brew is in the mid/upper 30's (fridge temps)... Most of the year, I should be able to keep the glasses to under the mid 80's, even in the middle of the summer time. So even with a 50F difference, the brew should still be in the 40-55F range...
I will say that it changes the character of the brew... I didn't really like one batch when put in a frosted glass. Put that same brew into a room temp glass and it's great. Go figure...
BTW, I believe the Brit's also do this method... So it's pretty common in the 'old world'... Just most Americans seem to think that you need to freeze the glasses in order to get a great brew...
Didn't say we do it better...
I'm brewing styles from the British Isles right now, so serving them in a frosted glass is beyond wrong...
Even when I was buying my beer, I wouldn't spend money on BMC... In college, I almost never drank beer because I couldn't really find anything that I liked. Now, at least there's some decent beer available either at the better stores, or places you go out to. I do cringe when someone either orders a BMC, or walks up with one in their hand (sucking on the bottle)... Probably the same kind of person that thinks McDonalds makes the best burgers in the world...
+1. Most beers tend to really open up in flavor and aroma ~10 below room temp.
The reason BMC wants you to drink their beer ice cold is because it tastes like doo-doo.
Most of my brews would probably lay you out if you did that, on an empty stomach...
Let's see. Room temp in say July in an un-air conditioned house 80-85, beer 10 below - 70*. Not gonna drink that for sure.
Should have been more specific. Not Hawaii room-temp. Portland room temp
I understand, most of the homes on the "mainland" are heated and air conditioned. To save money heating is kept in the 60's at night which is great for brewing and perhaps 70's during the days.
My home has open windows to catch the mountain or sea breeze most of the time, but when we lock up, man it can get hot inside. Think I need a cool one.
Actually, up where I am, most houses are heated, but not many have central air... Most of us are stuck with window AC units to fight the heat during the summer. Luckily, we don't get a lot of HOT days each year... Maybe 2-4 weeks total, on average. Still, it's nice to have your place below 80F when you get home in the summer. It also helps when you can sleep in a bit cooler temps (I like it under 70-75F for sleeping)...
So, not counting during the summer, when it can get hot/nasty, glasses are around/under ~70-75F up here... So, from ~35F to 75F is a 40F shift... Even if the brew gets warmed 20F by the glass (could be stretching it) it would still be in the 55F area...
When summer hits, if I'm still where I am not (I do so hope that I'm not) I'll have to test with a room temp glass, and maybe another put into the freezer for a very short amount of time. I'm talking about maybe 10-15 minutes to start... I'll probably try in the fridge too, just to see how it compares... Of course, it will be even easier when I get a keezer... Then, I can just set it's temp, and store the glasses right there too.
Even in the summer, if there is a night time mauka (from the mts) breeze sleeping temps are in the mid 70's. Winter nights it can go down to low 60's which means for us thin blooded people pulling up the quilts. :0)
We have a name for people like you where I am...
Hope it's not WIMP!
Maybe you call us lucky for living in paradise.
I hike every Wed and Sun. Done K1-K2 great hike. PM me if you want to continue to talk bout hiking.
