Default Boozy, phenolic taste

The last three brews I made have a distinctly boozy and phenolic taste and I cannot explain why this happened. The only thing I did differently was the use of Maris otter malt. I mashed correctly and hit the appropriate finishing gravity. Can anyone explain this to me?

I'll also add that the fermentation temperature was steady at about 62-64 degrees and I believe that my yeast pitch rate was enough for the starting gravity

With the limited info here about style and recipe. I would think you underpitched your yeast (did you make a starter?)

The first bee I noticed it in was a recipe I created, an English India brown ale, the second was a nut brown ale recipe from this site that I secondaried on some toasted coconut. I used a rehydrated pack of Nottingham dry yeast which should contain enough to get the job done correctly. I recently started using plastic buckets as primary fermenters, so maybe it is that?

It was the reading of the stick on thermometer on the side of the bucket... I actually increased the temp in the room to that temperature because it was around 58-60 before and I was worries the yeast would go dormant

I think cold can stress a yeast just like heat. You also might need a little nutrient blend, maybe the nitrogen in that particular batch of malt is lower than normal.

I always use yeast nutrient at the end of the boil. I wasn't aware that a ferment temperature being too cool could cause off flavors. If that is true, that could have been the problem

What temp did you pitch? I have found (I know different strain of yeast) that if I pitch belgian ale yeast when the wort is between 70-80F, I get hot solventy flavors, even if I control the fermentation temp in my freezer chest at 64F for the rest of the fermentation. Now with all my beers I chill to at or bellow my target fermentation temperature before pitching.

Did you use special roast malt?

Alpha Klaus porter and a darker beer I made had a similar flavor. Maybe it's just the way the dark malts are interacting with other malts.
