(2) We’ll need about 10 bottles of wine, I think.
What is the difference between them?
Does (1) sound less certain than (2)?

In reality there is no difference in meaning between "I think" and "I would think" but I retain there can be a nuance between the two forms.
I would think refers to knowledge based on the information that is available at that time.
For instance, the speaker knows there are 12 guests coming to a dinner party, none of whom are teetotallers but maybe one or two are heavy drinkers, so the speaker surmises that ten bottles will be more than enough.
Personal preference, not a rule as such, but I'd place "I think" at the beginning of the sentence
I think we'll need about 10 bottles of wine
when you express an opinion that is connected to the future, it's quite common to say "I think" followed by a clause (subject + verb).
Saying "We'll need ..., I think" means you are totally guessing.
Saying "We'll need ..., I would think" means you are making an educated guess based on your prior knowledge.
Neither implies hesitancy in the response.
