On a new farm, coffee in spring year 1 will set you up for really early success financially. It has a higher gpd than pale ale, requires no kegs to be profitable, has no overhead aside from the initial purchase, it grows through the end of summer, and does not need a seed maker to proliferate. If you can get a single coffee bean in week 1 from the gypsy, you won't need to worry about growing much else.
Eh, the thing with the coffee strategy is that it just takes so much watering if you want to get a large enough field to get any decent money. Takes up all your time and energy early game, when both those resources are precious.
Plus, you're not taking into account the strategy of using jars (which you can get much faster and somewhat easier than kegs) to make more money.
That initial coffee bean costs, what, 2500? Instead of buying it from the gypsy on Friday Spring 5, lets say you buy 30 potato seeds instead, which costs significantly less (only 1500). They sell for 30*80 = 2400 on Spring 11. Then you use that money to buy 24 strawberry seeds at the egg festival, which give you two harvests over the rest of the season, producing 24*2*120 = 5760g.
Let's assume you don't have sprinklers yet by the end of spring, so you still want a fairly small field. So you buy 50 melon seeds (costing 4000), leaving you with an extra 1760g to do whatever you want with. You can plant them 25 at a time, so you're still only watering 25 spots.
If you can get even 5 floors in a day, getting to iron levels of the mines by the end of spring should be quite doable. With the coal from dust sprites plus whatever you have from the minecarts/breaking rocks, 24 coal should be nothing. 150 wood is only about 7 trees, and 120 stone shouldn't be hard either, from that mining. So make at least 3 jars, and you'll get 1050 per melon jelly, or 3150 every three days for almost two months, or 50*1050 = 52500 total. I'd be very surprised if coffee could rival that, and certainly you'd have to water more than 24-30 spots a day to rival that with coffee.
Side note, if you don't enjoy mining and don't have the coal for jars or the money to buy coal from Clint, replace the melons with blueberries. It's not as much money but it can definitely still rival coffee, especially if you consider that most of the coffee beans won't be planted until the 15th of spring or later and so will only give 15 or less harvests, for a total of 15*4*15 = 900 gold each. If you get one potato + one strawberry + one blueberry in the same spot, you get 80+2*120+16*50 = 1120 gold, minus the seed price of 50+100+100 = 250, for profit of 870. So the coffee is slightly more, but only if you plant on the 16th of spring or earlier. If your source of coffee beans is the travelling cart, then the earliest you can get one is the 5th of spring, and it'll produce for the first time on the 15th, so at most you can plant 5 coffee plants before the 16th. That extra 30 gold per plant, times 5 plants, doesn't even make up for the 2500 you spent on the initial coffee bean.
Of course, if you enjoy making coffee, go ahead! Not trying to knock anyone's play style, heck I plant some myself in casual games, just saying that coffee isn't the moneymaker many people think it is.
TL;DR skip the coffee year 1, go for high-value crops like potatoes, kale, strawberries, blueberries, or melons instead, get a few jars when you can and process the melons for $$$.
