<p>I use Maxwell House instant coffee.  It is freeze dried, which adds nothing to the coffee. I have an acute sense of smell, yet, I've never noticed an odd smell from the Maxwell House, only, a lack of smell. Then upon further examination,  discovered the jar was near it's expiration date. My theory is, that since your group opened it and all noted the "soy" smell...but, then, the taste was normal. That something in your environment was contribbing to the scent, and the coffee in a different environment would have smelled normal.</p>

<p>My office just got a case of Maxwell House instant coffee. As noted by my co-worker, the aroma of the coffee powder smells more like <em>soy sauce</em> than coffee, which most of the instant coffees we had. </p>

<p>The actual coffee tasted fine, the initial aroma was just offsetting. Is there any specific reason (maybe in the method of processing) for why the aroma of Maxwell House instant coffee powder smells this way? </p>

# Maxwell house instant coffee powder aroma

(Asked by: username_0 on 2017-08-21)

My office just got a case of Maxwell House instant coffee. As noted by my co-worker, the aroma of the coffee powder smells more like *soy sauce* than coffee, which most of the instant coffees we had.

The actual coffee tasted fine, the initial aroma was just offsetting. Is there any specific reason (maybe in the method of processing) for why the aroma of Maxwell House instant coffee powder smells this way?
