Since you have depreciation in your assumptions, I assume you have figured in the applicable tax rates. Keep in mind that your social security, retirement, interest income, and minimum IRA distributions will be fully taxable, so use the tax rate for the NEXT dollar that comes in (e.g. the highest tax bracket you expect to attain in retirement). You can write off some other stuff, too. Office supplies (you're already using paper, toner, files, etc), bank fees (all those bounced checks from customers), mileage (to sell the honey), etc.
I think the bottles and anything used up right away (sugar?) will not be depreciated, by the way. They should be expensed in the year purchased. Technically, they would be expensed in the year you sell the honey but don't worry about that in your modeling.
Where did you come up with 6 year depreciable life? Is that an IRS determination? Is that MACRs? Usually, you'll want to use MACRs depreciation. fyi--developing depreciation tables in Excel is always a pain if you have many levels of depreciation (different depreciable lives and new depreciable assets every year).
Caveat--I'm not a tax accountant, and this should not be construed as or used for tax or accounting advice.
But I have done hundreds of pro formas (income statement projections for imaginary businesses). I find that keeping it simple is the best approach. If you pay an Investment Banker $1,000,000, they will take 5 pages of financials and turn it into 500 pages of gobbledy-gook and try to make you feel stupid under their superior stares. Hey, they have to prove their worth somehow, right?
Rule of thumb is that you almost never earn the returns that you project...so project high! :-D
