Need some feedback on tobacco taste/enjoyment:

I'm looking for feedback from primarily the more experienced, everyday pipe smoker but I'm not limiting it to just those types as I welcome ALL the answers that I can get.
I'm curious if others ever experience what I've gone through over the last several days as it relates to tobacco taste. We are dealing with the same 3 open tins of English/Balkan blends and they are being smoked in a rotation of both high to mid grade briar as well as a couple cobs thrown in for good measure. The blends in question are Dunhills EMP, Ashton's Artisan and Bill Baileys Balkan Blend. I generally start my mornings with coffee and a bowl of EMP, the rest of the day and evening depending on what life throws at me will usually allow for another pipeful or 2 of one or both of the remaining blends.

Everything was going along swimmingly up until this past weekend when suddenly, without warning, I stopped tasting the tobacco!! What I mean is that the usual sweet and nutty bursts of flavor just weren't happening for me. It was as if all my tobacco had gone through the washing machine or something got sprayed on it, I don't know what it was. I became mindful of my packing ritual, my cadence, breathing, etc. and before you ask, yes, all my pipes were clean as they always are. All this was going on for like 4 days and then this morning rolls around and I load a LaRocca billiard of mine up with EMP, grab my coffee and go out on the porch to enjoy the morning and BAM! It's like I hit the pipe smoking lottery! All the tastes and nuances that make us think and talk and write about pipes and smoking are coming through in high definition, it's almost dream like. Determined to make sure this was not some kind of anomoly, after finishing my first pipe of the day and running some errands, I load up my Radice billiard with some Artisans blend and WOW! It was like I was tasting this delicious tobacco for the first time again ( it is a wonderful blend) and so it went for the rest of the day. I'm enjoying the same blend in a cob right now and will consider another, it's been that kind of a day.
My question to all of you is this, has this ever happened to you and if so, what's your explanation? I just can't pin down why my taste or perception of taste for my pipe tobacco just dried up on me and this has happened before but not for a while. I'm not getting a cold or any other illness (that I'm aware of) and food and drink tasted normal while this all going on as well. I'm interested in hearing what others have to say about this kind of phenomenon.

Glad to see that it's not just me. One thing that I'm thinking may have contributed to the flatness or lackluster performance of my favorite tobaccos is over smoking. I may have been putting in too much time puffing now that the weather is ever so slowly starting to break and behave like Spring. A little tongue rest may have been the ticket.

Some great feedback and to rmbittners advice to expand the selection, I like the concept. I do occasionally dip into my stash of well aged VaPer (Haddo's) and it does shake things up as far as taste goes. Another weird thing I've noticed over time is that when I smoke a newer or different blend for a while and then revert back to an old standby that I have jarred, it often tastes much different. Sometime it's a welcome, refreshing change and other times not so much. I get that this all part of the pipe smoking life and it's all good as far as that goes and I enjoy hearing other peoples take on it.

At the risk of hijacking my own thread I'd like to ask how many of you actually "taste" your briar? I've only recently become aware of what I was tasting only because I started smoking cobs quite regularly. I can say honestly that I now have a tremendous amount of respect for those inexpensive MM brand instruments and I'm also convinced that the act of smoking them has heightened my enjoyment of my briar pipes. With the cob I can taste just the tobacco. With a well made, cared for briar, I can amplify the subtle flavor changes brought out in the blend. I also think that just discussing things along the lines of the OP helps me with my perception of the blend I'm smoking. Keep it coming!

I'm real glad a thread like this popped up because I am going through that "taste disappearance" thing right now.
A few weeks back, I was enjoying all my blends in rotation. Then one day last week, it felt like my tongue had gone bland. I couldn't taste any of the tobaccos I smoked - absolutely nothing. Not the aromatics I liked, not the englishes. It was strange. To this day, I had a bowl of northwoods last night, and I still couldn't taste anything.
Interesting, I'll be curious how long it takes you to get back to your baseline. I don't know if it turned things around for me or not but what I did after my last un-fulfilling smoke was to just back off a bit. I gave every one of my pipes a thorough scrubbing/cleaning and let them all rest for a whole day before loading the next bowl that was due in my rotation. I also made it a point to slow down on everything in my process, from drying, packing, charring light to true light and stayed focused on my smoking cadence as to not push things and smoke too hot. So far, so good. I wish you luck as well.
