Absolutely!
In Sydney, I believe the primary reason is asset protection. Exactly like you say... you want the "up time" of the machine to be as high as possible. Replacing the water filter (~$100) every 6-12 months is cheap insurance to keep trouble away. Taste may be an auxiliary benefit. We probably have 10 cafes that exist to punch out a morning and lunchtime workload for every boutique cafe that has put serious thought into their taste profile. It is clear who is thinking about what (not meaning to cast judgement either way - both are useful business models).
I might consider filtering if my coffee machine was >$10K. Since Sydney has soft water, descaling is not a massive concern. Though I will admit... I am a little uneasy about my boiler having brass end caps
Pour over being the theme of this thread!
I remain interested in the recommendations. We purchased a v60 kit at the beginning of the year but are using it less than expected. But that is my fault. I really dislike using our grinder for
both espresso and pour-over. Changing it back and forth is really irritating once the espresso is dialed in.
I am close to commiting to the Fellow Ode but am having a difficult time justifying the cost (in addition to our other grinder). The next step for me mostly depends on how dissatisfied my partner is about my lack of action on this purchase
